How To Write A Research Paper

Step-By-Step Tutorial With Examples + FREE Template

By: Derek Jansen (MBA) | Expert Reviewer: Dr Eunice Rautenbach | March 2024

For many students, crafting a strong research paper from scratch can feel like a daunting task – and rightly so! In this post, we’ll unpack what a research paper is, what it needs to do , and how to write one – in three easy steps. 🙂 

Overview: Writing A Research Paper

What (exactly) is a research paper.

• How to write a research paper
• Stage 1 : Topic & literature search
• Stage 2 : Structure & outline
• Stage 3 : Iterative writing
• Key takeaways

Let’s start by asking the most important question, “ What is a research paper? ”.

Simply put, a research paper is a scholarly written work where the writer (that’s you!) answers a specific question (this is called a research question ) through evidence-based arguments . Evidence-based is the keyword here. In other words, a research paper is different from an essay or other writing assignments that draw from the writer’s personal opinions or experiences. With a research paper, it’s all about building your arguments based on evidence (we’ll talk more about that evidence a little later).

Now, it’s worth noting that there are many different types of research papers , including analytical papers (the type I just described), argumentative papers, and interpretative papers. Here, we’ll focus on analytical papers , as these are some of the most common – but if you’re keen to learn about other types of research papers, be sure to check out the rest of the blog .

With that basic foundation laid, let’s get down to business and look at how to write a research paper .

Overview: The 3-Stage Process

While there are, of course, many potential approaches you can take to write a research paper, there are typically three stages to the writing process. So, in this tutorial, we’ll present a straightforward three-step process that we use when working with students at Grad Coach.

These three steps are:

• Finding a research topic and reviewing the existing literature
• Developing a provisional structure and outline for your paper, and
• Writing up your initial draft and then refining it iteratively

Let’s dig into each of these.

Need a helping hand?

Step 1: Find a topic and review the literature

As we mentioned earlier, in a research paper, you, as the researcher, will try to answer a question . More specifically, that’s called a research question , and it sets the direction of your entire paper. What’s important to understand though is that you’ll need to answer that research question with the help of high-quality sources – for example, journal articles, government reports, case studies, and so on. We’ll circle back to this in a minute.

The first stage of the research process is deciding on what your research question will be and then reviewing the existing literature (in other words, past studies and papers) to see what they say about that specific research question. In some cases, your professor may provide you with a predetermined research question (or set of questions). However, in many cases, you’ll need to find your own research question within a certain topic area.

Finding a strong research question hinges on identifying a meaningful research gap – in other words, an area that’s lacking in existing research. There’s a lot to unpack here, so if you wanna learn more, check out the plain-language explainer video below.

Once you’ve figured out which question (or questions) you’ll attempt to answer in your research paper, you’ll need to do a deep dive into the existing literature – this is called a “ literature search ”. Again, there are many ways to go about this, but your most likely starting point will be Google Scholar .

If you’re new to Google Scholar, think of it as Google for the academic world. You can start by simply entering a few different keywords that are relevant to your research question and it will then present a host of articles for you to review. What you want to pay close attention to here is the number of citations for each paper – the more citations a paper has, the more credible it is (generally speaking – there are some exceptions, of course).

Ideally, what you’re looking for are well-cited papers that are highly relevant to your topic. That said, keep in mind that citations are a cumulative metric , so older papers will often have more citations than newer papers – just because they’ve been around for longer. So, don’t fixate on this metric in isolation – relevance and recency are also very important.

Beyond Google Scholar, you’ll also definitely want to check out academic databases and aggregators such as Science Direct, PubMed, JStor and so on. These will often overlap with the results that you find in Google Scholar, but they can also reveal some hidden gems – so, be sure to check them out.

Once you’ve worked your way through all the literature, you’ll want to catalogue all this information in some sort of spreadsheet so that you can easily recall who said what, when and within what context. If you’d like, we’ve got a free literature spreadsheet that helps you do exactly that.

Step 2: Develop a structure and outline

With your research question pinned down and your literature digested and catalogued, it’s time to move on to planning your actual research paper .

It might sound obvious, but it’s really important to have some sort of rough outline in place before you start writing your paper. So often, we see students eagerly rushing into the writing phase, only to land up with a disjointed research paper that rambles on in multiple

Now, the secret here is to not get caught up in the fine details . Realistically, all you need at this stage is a bullet-point list that describes (in broad strokes) what you’ll discuss and in what order. It’s also useful to remember that you’re not glued to this outline – in all likelihood, you’ll chop and change some sections once you start writing, and that’s perfectly okay. What’s important is that you have some sort of roadmap in place from the start.

At this stage you might be wondering, “ But how should I structure my research paper? ”. Well, there’s no one-size-fits-all solution here, but in general, a research paper will consist of a few relatively standardised components:

• Introduction
• Literature review
• Methodology

Let’s take a look at each of these.

First up is the introduction section . As the name suggests, the purpose of the introduction is to set the scene for your research paper. There are usually (at least) four ingredients that go into this section – these are the background to the topic, the research problem and resultant research question , and the justification or rationale. If you’re interested, the video below unpacks the introduction section in more detail. 

The next section of your research paper will typically be your literature review . Remember all that literature you worked through earlier? Well, this is where you’ll present your interpretation of all that content . You’ll do this by writing about recent trends, developments, and arguments within the literature – but more specifically, those that are relevant to your research question . The literature review can oftentimes seem a little daunting, even to seasoned researchers, so be sure to check out our extensive collection of literature review content here .

With the introduction and lit review out of the way, the next section of your paper is the research methodology . In a nutshell, the methodology section should describe to your reader what you did (beyond just reviewing the existing literature) to answer your research question. For example, what data did you collect, how did you collect that data, how did you analyse that data and so on? For each choice, you’ll also need to justify why you chose to do it that way, and what the strengths and weaknesses of your approach were.

Now, it’s worth mentioning that for some research papers, this aspect of the project may be a lot simpler . For example, you may only need to draw on secondary sources (in other words, existing data sets). In some cases, you may just be asked to draw your conclusions from the literature search itself (in other words, there may be no data analysis at all). But, if you are required to collect and analyse data, you’ll need to pay a lot of attention to the methodology section. The video below provides an example of what the methodology section might look like.

By this stage of your paper, you will have explained what your research question is, what the existing literature has to say about that question, and how you analysed additional data to try to answer your question. So, the natural next step is to present your analysis of that data . This section is usually called the “results” or “analysis” section and this is where you’ll showcase your findings.

Depending on your school’s requirements, you may need to present and interpret the data in one section – or you might split the presentation and the interpretation into two sections. In the latter case, your “results” section will just describe the data, and the “discussion” is where you’ll interpret that data and explicitly link your analysis back to your research question. If you’re not sure which approach to take, check in with your professor or take a look at past papers to see what the norms are for your programme.

Alright – once you’ve presented and discussed your results, it’s time to wrap it up . This usually takes the form of the “ conclusion ” section. In the conclusion, you’ll need to highlight the key takeaways from your study and close the loop by explicitly answering your research question. Again, the exact requirements here will vary depending on your programme (and you may not even need a conclusion section at all) – so be sure to check with your professor if you’re unsure.

Step 3: Write and refine

Finally, it’s time to get writing. All too often though, students hit a brick wall right about here… So, how do you avoid this happening to you?

Well, there’s a lot to be said when it comes to writing a research paper (or any sort of academic piece), but we’ll share three practical tips to help you get started.

First and foremost , it’s essential to approach your writing as an iterative process. In other words, you need to start with a really messy first draft and then polish it over multiple rounds of editing. Don’t waste your time trying to write a perfect research paper in one go. Instead, take the pressure off yourself by adopting an iterative approach.

Secondly , it’s important to always lean towards critical writing , rather than descriptive writing. What does this mean? Well, at the simplest level, descriptive writing focuses on the “ what ”, while critical writing digs into the “ so what ” – in other words, the implications. If you’re not familiar with these two types of writing, don’t worry! You can find a plain-language explanation here.

Last but not least, you’ll need to get your referencing right. Specifically, you’ll need to provide credible, correctly formatted citations for the statements you make. We see students making referencing mistakes all the time and it costs them dearly. The good news is that you can easily avoid this by using a simple reference manager . If you don’t have one, check out our video about Mendeley, an easy (and free) reference management tool that you can start using today.

Recap: Key Takeaways

We’ve covered a lot of ground here. To recap, the three steps to writing a high-quality research paper are:

• To choose a research question and review the literature
• To plan your paper structure and draft an outline
• To take an iterative approach to writing, focusing on critical writing and strong referencing

Research Paper – Structure, Examples and Writing Guide

Table of Contents

Research Paper

Definition:

Research Paper is a written document that presents the author’s original research, analysis, and interpretation of a specific topic or issue.

It is typically based on Empirical Evidence, and may involve qualitative or quantitative research methods, or a combination of both. The purpose of a research paper is to contribute new knowledge or insights to a particular field of study, and to demonstrate the author’s understanding of the existing literature and theories related to the topic.

Structure of Research Paper

The structure of a research paper typically follows a standard format, consisting of several sections that convey specific information about the research study. The following is a detailed explanation of the structure of a research paper:

The title page contains the title of the paper, the name(s) of the author(s), and the affiliation(s) of the author(s). It also includes the date of submission and possibly, the name of the journal or conference where the paper is to be published.

The abstract is a brief summary of the research paper, typically ranging from 100 to 250 words. It should include the research question, the methods used, the key findings, and the implications of the results. The abstract should be written in a concise and clear manner to allow readers to quickly grasp the essence of the research.

Introduction

The introduction section of a research paper provides background information about the research problem, the research question, and the research objectives. It also outlines the significance of the research, the research gap that it aims to fill, and the approach taken to address the research question. Finally, the introduction section ends with a clear statement of the research hypothesis or research question.

Literature Review

The literature review section of a research paper provides an overview of the existing literature on the topic of study. It includes a critical analysis and synthesis of the literature, highlighting the key concepts, themes, and debates. The literature review should also demonstrate the research gap and how the current study seeks to address it.

The methods section of a research paper describes the research design, the sample selection, the data collection and analysis procedures, and the statistical methods used to analyze the data. This section should provide sufficient detail for other researchers to replicate the study.

The results section presents the findings of the research, using tables, graphs, and figures to illustrate the data. The findings should be presented in a clear and concise manner, with reference to the research question and hypothesis.

The discussion section of a research paper interprets the findings and discusses their implications for the research question, the literature review, and the field of study. It should also address the limitations of the study and suggest future research directions.

The conclusion section summarizes the main findings of the study, restates the research question and hypothesis, and provides a final reflection on the significance of the research.

The references section provides a list of all the sources cited in the paper, following a specific citation style such as APA, MLA or Chicago.

How to Write Research Paper

You can write Research Paper by the following guide:

• Choose a Topic: The first step is to select a topic that interests you and is relevant to your field of study. Brainstorm ideas and narrow down to a research question that is specific and researchable.
• Conduct a Literature Review: The literature review helps you identify the gap in the existing research and provides a basis for your research question. It also helps you to develop a theoretical framework and research hypothesis.
• Develop a Thesis Statement : The thesis statement is the main argument of your research paper. It should be clear, concise and specific to your research question.
• Plan your Research: Develop a research plan that outlines the methods, data sources, and data analysis procedures. This will help you to collect and analyze data effectively.
• Collect and Analyze Data: Collect data using various methods such as surveys, interviews, observations, or experiments. Analyze data using statistical tools or other qualitative methods.
• Organize your Paper : Organize your paper into sections such as Introduction, Literature Review, Methods, Results, Discussion, and Conclusion. Ensure that each section is coherent and follows a logical flow.
• Write your Paper : Start by writing the introduction, followed by the literature review, methods, results, discussion, and conclusion. Ensure that your writing is clear, concise, and follows the required formatting and citation styles.
• Edit and Proofread your Paper: Review your paper for grammar and spelling errors, and ensure that it is well-structured and easy to read. Ask someone else to review your paper to get feedback and suggestions for improvement.
• Cite your Sources: Ensure that you properly cite all sources used in your research paper. This is essential for giving credit to the original authors and avoiding plagiarism.

Title: The Impact of Social Media on Mental Health among Young Adults

Abstract: This study aims to investigate the impact of social media use on the mental health of young adults. A literature review was conducted to examine the existing research on the topic. A survey was then administered to 200 university students to collect data on their social media use, mental health status, and perceived impact of social media on their mental health. The results showed that social media use is positively associated with depression, anxiety, and stress. The study also found that social comparison, cyberbullying, and FOMO (Fear of Missing Out) are significant predictors of mental health problems among young adults.

Introduction: Social media has become an integral part of modern life, particularly among young adults. While social media has many benefits, including increased communication and social connectivity, it has also been associated with negative outcomes, such as addiction, cyberbullying, and mental health problems. This study aims to investigate the impact of social media use on the mental health of young adults.

Literature Review: The literature review highlights the existing research on the impact of social media use on mental health. The review shows that social media use is associated with depression, anxiety, stress, and other mental health problems. The review also identifies the factors that contribute to the negative impact of social media, including social comparison, cyberbullying, and FOMO.

Methods : A survey was administered to 200 university students to collect data on their social media use, mental health status, and perceived impact of social media on their mental health. The survey included questions on social media use, mental health status (measured using the DASS-21), and perceived impact of social media on their mental health. Data were analyzed using descriptive statistics and regression analysis.

Results : The results showed that social media use is positively associated with depression, anxiety, and stress. The study also found that social comparison, cyberbullying, and FOMO are significant predictors of mental health problems among young adults.

Discussion : The study’s findings suggest that social media use has a negative impact on the mental health of young adults. The study highlights the need for interventions that address the factors contributing to the negative impact of social media, such as social comparison, cyberbullying, and FOMO.

Conclusion : In conclusion, social media use has a significant impact on the mental health of young adults. The study’s findings underscore the need for interventions that promote healthy social media use and address the negative outcomes associated with social media use. Future research can explore the effectiveness of interventions aimed at reducing the negative impact of social media on mental health. Additionally, longitudinal studies can investigate the long-term effects of social media use on mental health.

Limitations : The study has some limitations, including the use of self-report measures and a cross-sectional design. The use of self-report measures may result in biased responses, and a cross-sectional design limits the ability to establish causality.

Implications: The study’s findings have implications for mental health professionals, educators, and policymakers. Mental health professionals can use the findings to develop interventions that address the negative impact of social media use on mental health. Educators can incorporate social media literacy into their curriculum to promote healthy social media use among young adults. Policymakers can use the findings to develop policies that protect young adults from the negative outcomes associated with social media use.

• How to write a research paper

Last updated

11 January 2024

Reviewed by

With proper planning, knowledge, and framework, completing a research paper can be a fulfilling and exciting experience. 

Though it might initially sound slightly intimidating, this guide will help you embrace the challenge. 

By documenting your findings, you can inspire others and make a difference in your field. Here's how you can make your research paper unique and comprehensive.

• What is a research paper?

Research papers allow you to demonstrate your knowledge and understanding of a particular topic. These papers are usually lengthier and more detailed than typical essays, requiring deeper insight into the chosen topic.

To write a research paper, you must first choose a topic that interests you and is relevant to the field of study. Once you’ve selected your topic, gathering as many relevant resources as possible, including books, scholarly articles, credible websites, and other academic materials, is essential. You must then read and analyze these sources, summarizing their key points and identifying gaps in the current research.

You can formulate your ideas and opinions once you thoroughly understand the existing research. To get there might involve conducting original research, gathering data, or analyzing existing data sets. It could also involve presenting an original argument or interpretation of the existing research.

Writing a successful research paper involves presenting your findings clearly and engagingly, which might involve using charts, graphs, or other visual aids to present your data and using concise language to explain your findings. You must also ensure your paper adheres to relevant academic formatting guidelines, including proper citations and references.

Overall, writing a research paper requires a significant amount of time, effort, and attention to detail. However, it is also an enriching experience that allows you to delve deeply into a subject that interests you and contribute to the existing body of knowledge in your chosen field.

• How long should a research paper be?

Research papers are deep dives into a topic. Therefore, they tend to be longer pieces of work than essays or opinion pieces. 

However, a suitable length depends on the complexity of the topic and your level of expertise. For instance, are you a first-year college student or an experienced professional? 

Also, remember that the best research papers provide valuable information for the benefit of others. Therefore, the quality of information matters most, not necessarily the length. Being concise is valuable.

Following these best practice steps will help keep your process simple and productive:

1. Gaining a deep understanding of any expectations

Before diving into your intended topic or beginning the research phase, take some time to orient yourself. Suppose there’s a specific topic assigned to you. In that case, it’s essential to deeply understand the question and organize your planning and approach in response. Pay attention to the key requirements and ensure you align your writing accordingly. 

This preparation step entails

Deeply understanding the task or assignment

Being clear about the expected format and length

Familiarizing yourself with the citation and referencing requirements 

Understanding any defined limits for your research contribution

Where applicable, speaking to your professor or research supervisor for further clarification

2. Choose your research topic

Select a research topic that aligns with both your interests and available resources. Ideally, focus on a field where you possess significant experience and analytical skills. In crafting your research paper, it's crucial to go beyond summarizing existing data and contribute fresh insights to the chosen area.

Consider narrowing your focus to a specific aspect of the topic. For example, if exploring the link between technology and mental health, delve into how social media use during the pandemic impacts the well-being of college students. Conducting interviews and surveys with students could provide firsthand data and unique perspectives, adding substantial value to the existing knowledge.

When finalizing your topic, adhere to legal and ethical norms in the relevant area (this ensures the integrity of your research, protects participants' rights, upholds intellectual property standards, and ensures transparency and accountability). Following these principles not only maintains the credibility of your work but also builds trust within your academic or professional community.

For instance, in writing about medical research, consider legal and ethical norms, including patient confidentiality laws and informed consent requirements. Similarly, if analyzing user data on social media platforms, be mindful of data privacy regulations, ensuring compliance with laws governing personal information collection and use. Aligning with legal and ethical standards not only avoids potential issues but also underscores the responsible conduct of your research.

3. Gather preliminary research

Once you’ve landed on your topic, it’s time to explore it further. You’ll want to discover more about available resources and existing research relevant to your assignment at this stage. 

This exploratory phase is vital as you may discover issues with your original idea or realize you have insufficient resources to explore the topic effectively. This key bit of groundwork allows you to redirect your research topic in a different, more feasible, or more relevant direction if necessary. 

Spending ample time at this stage ensures you gather everything you need, learn as much as you can about the topic, and discover gaps where the topic has yet to be sufficiently covered, offering an opportunity to research it further. 

4. Define your research question

To produce a well-structured and focused paper, it is imperative to formulate a clear and precise research question that will guide your work. Your research question must be informed by the existing literature and tailored to the scope and objectives of your project. By refining your focus, you can produce a thoughtful and engaging paper that effectively communicates your ideas to your readers.

5. Write a thesis statement

A thesis statement is a one-to-two-sentence summary of your research paper's main argument or direction. It serves as an overall guide to summarize the overall intent of the research paper for you and anyone wanting to know more about the research.

A strong thesis statement is:

Concise and clear: Explain your case in simple sentences (avoid covering multiple ideas). It might help to think of this section as an elevator pitch.

Specific: Ensure that there is no ambiguity in your statement and that your summary covers the points argued in the paper.

Debatable: A thesis statement puts forward a specific argument––it is not merely a statement but a debatable point that can be analyzed and discussed.

Here are three thesis statement examples from different disciplines:

Psychology thesis example: "We're studying adults aged 25-40 to see if taking short breaks for mindfulness can help with stress. Our goal is to find practical ways to manage anxiety better."

Environmental science thesis example: "This research paper looks into how having more city parks might make the air cleaner and keep people healthier. I want to find out if more green spaces means breathing fewer carcinogens in big cities."

UX research thesis example: "This study focuses on improving mobile banking for older adults using ethnographic research, eye-tracking analysis, and interactive prototyping. We investigate the usefulness of eye-tracking analysis with older individuals, aiming to spark debate and offer fresh perspectives on UX design and digital inclusivity for the aging population."

6. Conduct in-depth research

A research paper doesn’t just include research that you’ve uncovered from other papers and studies but your fresh insights, too. You will seek to become an expert on your topic––understanding the nuances in the current leading theories. You will analyze existing research and add your thinking and discoveries.  It's crucial to conduct well-designed research that is rigorous, robust, and based on reliable sources. Suppose a research paper lacks evidence or is biased. In that case, it won't benefit the academic community or the general public. Therefore, examining the topic thoroughly and furthering its understanding through high-quality research is essential. That usually means conducting new research. Depending on the area under investigation, you may conduct surveys, interviews, diary studies, or observational research to uncover new insights or bolster current claims.

7. Determine supporting evidence

Not every piece of research you’ve discovered will be relevant to your research paper. It’s important to categorize the most meaningful evidence to include alongside your discoveries. It's important to include evidence that doesn't support your claims to avoid exclusion bias and ensure a fair research paper.

8. Write a research paper outline

Before diving in and writing the whole paper, start with an outline. It will help you to see if more research is needed, and it will provide a framework by which to write a more compelling paper. Your supervisor may even request an outline to approve before beginning to write the first draft of the full paper. An outline will include your topic, thesis statement, key headings, short summaries of the research, and your arguments.

9. Write your first draft

Once you feel confident about your outline and sources, it’s time to write your first draft. While penning a long piece of content can be intimidating, if you’ve laid the groundwork, you will have a structure to help you move steadily through each section. To keep up motivation and inspiration, it’s often best to keep the pace quick. Stopping for long periods can interrupt your flow and make jumping back in harder than writing when things are fresh in your mind.

10. Cite your sources correctly

It's always a good practice to give credit where it's due, and the same goes for citing any works that have influenced your paper. Building your arguments on credible references adds value and authenticity to your research. In the formatting guidelines section, you’ll find an overview of different citation styles (MLA, CMOS, or APA), which will help you meet any publishing or academic requirements and strengthen your paper's credibility. It is essential to follow the guidelines provided by your school or the publication you are submitting to ensure the accuracy and relevance of your citations.

11. Ensure your work is original

It is crucial to ensure the originality of your paper, as plagiarism can lead to serious consequences. To avoid plagiarism, you should use proper paraphrasing and quoting techniques. Paraphrasing is rewriting a text in your own words while maintaining the original meaning. Quoting involves directly citing the source. Giving credit to the original author or source is essential whenever you borrow their ideas or words. You can also use plagiarism detection tools such as Scribbr or Grammarly to check the originality of your paper. These tools compare your draft writing to a vast database of online sources. If you find any accidental plagiarism, you should correct it immediately by rephrasing or citing the source.

12. Revise, edit, and proofread

One of the essential qualities of excellent writers is their ability to understand the importance of editing and proofreading. Even though it's tempting to call it a day once you've finished your writing, editing your work can significantly improve its quality. It's natural to overlook the weaker areas when you've just finished writing a paper. Therefore, it's best to take a break of a day or two, or even up to a week, to refresh your mind. This way, you can return to your work with a new perspective. After some breathing room, you can spot any inconsistencies, spelling and grammar errors, typos, or missing citations and correct them. 

• The best research paper format 

The format of your research paper should align with the requirements set forth by your college, school, or target publication. 

There is no one “best” format, per se. Depending on the stated requirements, you may need to include the following elements:

Title page: The title page of a research paper typically includes the title, author's name, and institutional affiliation and may include additional information such as a course name or instructor's name. 

Table of contents: Include a table of contents to make it easy for readers to find specific sections of your paper.

Abstract: The abstract is a summary of the purpose of the paper.

Methods : In this section, describe the research methods used. This may include collecting data, conducting interviews, or doing field research.

Results: Summarize the conclusions you drew from your research in this section.

Discussion: In this section, discuss the implications of your research. Be sure to mention any significant limitations to your approach and suggest areas for further research.

Tables, charts, and illustrations: Use tables, charts, and illustrations to help convey your research findings and make them easier to understand.

Works cited or reference page: Include a works cited or reference page to give credit to the sources that you used to conduct your research.

Bibliography: Provide a list of all the sources you consulted while conducting your research.

Dedication and acknowledgments : Optionally, you may include a dedication and acknowledgments section to thank individuals who helped you with your research.

• General style and formatting guidelines

Formatting your research paper means you can submit it to your college, journal, or other publications in compliance with their criteria.

Research papers tend to follow the American Psychological Association (APA), Modern Language Association (MLA), or Chicago Manual of Style (CMOS) guidelines.

Here’s how each style guide is typically used:

Chicago Manual of Style (CMOS):

CMOS is a versatile style guide used for various types of writing. It's known for its flexibility and use in the humanities. CMOS provides guidelines for citations, formatting, and overall writing style. It allows for both footnotes and in-text citations, giving writers options based on their preferences or publication requirements.

American Psychological Association (APA):

APA is common in the social sciences. It’s hailed for its clarity and emphasis on precision. It has specific rules for citing sources, creating references, and formatting papers. APA style uses in-text citations with an accompanying reference list. It's designed to convey information efficiently and is widely used in academic and scientific writing.

Modern Language Association (MLA):

MLA is widely used in the humanities, especially literature and language studies. It emphasizes the author-page format for in-text citations and provides guidelines for creating a "Works Cited" page. MLA is known for its focus on the author's name and the literary works cited. It’s frequently used in disciplines that prioritize literary analysis and critical thinking.

To confirm you're using the latest style guide, check the official website or publisher's site for updates, consult academic resources, and verify the guide's publication date. Online platforms and educational resources may also provide summaries and alerts about any revisions or additions to the style guide.

Citing sources

When working on your research paper, it's important to cite the sources you used properly. Your citation style will guide you through this process. Generally, there are three parts to citing sources in your research paper: 

First, provide a brief citation in the body of your essay. This is also known as a parenthetical or in-text citation. 

Second, include a full citation in the Reference list at the end of your paper. Different types of citations include in-text citations, footnotes, and reference lists. 

In-text citations include the author's surname and the date of the citation. 

Footnotes appear at the bottom of each page of your research paper. They may also be summarized within a reference list at the end of the paper. 

A reference list includes all of the research used within the paper at the end of the document. It should include the author, date, paper title, and publisher listed in the order that aligns with your citation style.

10 research paper writing tips:

Following some best practices is essential to writing a research paper that contributes to your field of study and creates a positive impact.

These tactics will help you structure your argument effectively and ensure your work benefits others:

Engage in peer review: Seek feedback from peers or mentors to ensure the rigor and validity of your research. Peer review helps identify potential weaknesses in your methodology and strengthens the overall credibility of your findings.

• The real-world impact of research papers

Writing a research paper is more than an academic or business exercise. The experience provides an opportunity to explore a subject in-depth, broaden one's understanding, and arrive at meaningful conclusions. With careful planning, dedication, and hard work, writing a research paper can be a fulfilling and enriching experience contributing to advancing knowledge.

How do I publish my research paper? 

Many academics wish to publish their research papers. While challenging, your paper might get traction if it covers new and well-written information. To publish your research paper, find a target publication, thoroughly read their guidelines, format your paper accordingly, and send it to them per their instructions. You may need to include a cover letter, too. After submission, your paper may be peer-reviewed by experts to assess its legitimacy, quality, originality, and methodology. Following review, you will be informed by the publication whether they have accepted or rejected your paper. 

What is a good opening sentence for a research paper? 

Beginning your research paper with a compelling introduction can ensure readers are interested in going further. A relevant quote, a compelling statistic, or a bold argument can start the paper and hook your reader. Remember, though, that the most important aspect of a research paper is the quality of the information––not necessarily your ability to storytell, so ensure anything you write aligns with your goals.

Research paper vs. a research proposal—what’s the difference?

While some may confuse research papers and proposals, they are different documents. 

A research proposal comes before a research paper. It is a detailed document that outlines an intended area of exploration. It includes the research topic, methodology, timeline, sources, and potential conclusions. Research proposals are often required when seeking approval to conduct research. 

A research paper is a summary of research findings. A research paper follows a structured format to present those findings and construct an argument or conclusion.

How to Write a Research Paper

Undergrads often write research papers each semester, causing stress. Yet, it’s simpler than believing if you know how to write a research paper . Divide the task, get tips, a plan, and tools for an outstanding paper. Simplify research, writing, topic choice, and illustration use!

A research paper is an academic document that involves deep, independent research to offer analysis, interpretation, and argument. Unlike academic essays, research papers are lengthier and more detailed, aiming to evaluate your writing and scholarly research abilities. To write one, you must showcase expertise in your subject, interact with diverse sources, and provide a unique perspective to the discussion. 

Research papers are a foundational element of contemporary science and the most efficient means of disseminating knowledge throughout a broad network. Nonetheless, individuals usually encounter research papers during their education; they are frequently employed in college courses to assess a student’s grasp of a specific field or their aptitude for research. 

Given their significance, research papers adopt a research paper format – a formal, unadorned style that eliminates any subjective influence from the writing. Scientists present their discoveries straightforwardly, accompanied by relevant supporting proof, enabling other researchers to integrate the paper into their investigations.

This guide leads you through every steps to write a research paper , from grasping your task to refining your ultimate draft and will teach you how to write a research paper.

Understanding The Research Paper

A research paper is a meticulously structured document that showcases the outcomes of an inquiry, exploration, or scrutiny undertaken on a specific subject. It embodies a formal piece of academic prose that adds novel information, perspectives, or interpretations to a particular domain of study. Typically authored by scholars, researchers, scientists, or students as part of their academic or professional pursuits, these papers adhere to a well-defined format. This research paper format encompasses an introduction, literature review, methodology, results, discussion, and conclusion. 

The introduction provides context and outlines the study’s significance, while the literature review encapsulates existing research and situates the study within the broader academic discourse. The methodology section elucidates the research process, encompassing data collection and analysis techniques. Findings are presented in the results section, often complemented by graphical and statistical representations. Interpretation of findings, implications, and connection to existing knowledge transpire in the discussion section. 

Ultimately, the conclusion encapsulates pivotal discoveries and their wider import.

Research papers wield immense significance in advancing knowledge across diverse disciplines, enabling researchers to disseminate findings, theories, and revelations to a broader audience. Before publication in academic journals or presentations at conferences, these papers undergo a stringent peer review process conducted by domain experts, ensuring their integrity, precision, and worth.

Academic and non-academic research papers diverge across several dimensions. Academic papers are crafted for scholarly circles to expand domain knowledge and theories. They maintain a formal, objective tone and heavily rely on peer-reviewed sources for credibility. In contrast, non-academic papers, employing a more flexible writing style, target a broader audience or specific practical goals. These papers might incorporate persuasive language, anecdotes, and various sources beyond academia. While academic papers rigorously adhere to structured formats and established citation styles, non-academic papers prioritize practicality, adapting their structure and citation methods to suit the intended readership.

The purpose of a research paper revolves around offering fresh insights, knowledge, or interpretations within a specific field. This formal document serves as a conduit for scholars, researchers, scientists, and students to communicate their investigative findings and actively contribute to the ongoing academic discourse.

Research Paper Writing Process – How To Write a Good Research Paper

Selecting a suitable research topic .

Your initial task is to thoroughly review the assignment and carefully absorb the writing prompt’s details. Pay particular attention to technical specifications like length, formatting prerequisites (such as single- vs. double-spacing, indentation, etc.), and the required citation style. Also, pay attention to specifics, including an abstract or a cover page.

Once you’ve a clear understanding of the assignment, the subsequent steps to write a research paper are aligned with the conventional writing process. However, remember that research papers have rules, adding some extra considerations to the process.

When given some assignment freedom, the crucial task of choosing a topic rests on you. Despite its apparent simplicity, this choice sets the foundation for your entire research paper, shaping its direction. The primary factor in picking a research paper topic is ensuring it has enough material to support it. Your chosen topic should provide ample data and complexity for a thorough discussion. However, it’s important to avoid overly broad subjects and focus on specific ones that cover all relevant information without gaps. Yet, approach topic selection more slowly; choosing something that genuinely interests you is still valuable. Aim for a topic that meets both criteria—delivering substantial content while maintaining engagement.

Conducting Thorough Research 

Commence by delving into your research early to refine your topic and shape your thesis statement. Swift engagement with available research aids in dispelling misconceptions and unveils optimal paths and strategies to gather more material. Typically, research sources can be located either online or within libraries. When navigating online sources, exercise caution and opt for reputable outlets such as scientific journals or academic papers. Specific search engines, outlined below in the Tools and Resources section, exclusively enable exploring accredited sources and academic databases.

While pursuing information, it’s essential to differentiate between primary and secondary sources. Primary sources entail firsthand accounts, encompassing published articles or autobiographies, while secondary sources, such as critical reviews or secondary biographies, are more distanced. Skimming sources instead of reading each part proves more efficient during the research phase. If a source shows promise, set it aside for more in-depth reading later. Doing so prevents you from investing excessive time in sources that won’t contribute substantively to your work. You should present a literature review detailing your references and submit them for validation in certain instances. 

Organizing And Structuring The Research Paper

According to the research paper format , an outline for a research paper is a catalogue of essential topics, arguments, and evidence you intend to incorporate. These elements are divided into sections with headings, offering a preliminary overview of the paper’s structure before commencing the writing process. Formulating a structural outline can significantly enhance writing efficiency, warranting an investment of time to establish one.

Start by generating a list encompassing crucial categories and subtopics—a preliminary outline. Reflect on the amassed information while gathering supporting evidence, pondering the most effective means of segregation and categorization.

Once a discussion list is compiled, deliberate on the optimal information presentation sequence and identify related subtopics that should be placed adjacent. Consider if any subtopic loses coherence when presented out of order. Adopting a chronological arrangement can be suitable if the information follows a straightforward trajectory.

Given the potential complexity of research papers, consider breaking down the outline into paragraphs. This aids in maintaining organization when dealing with copious information and provides better control over the paper’s progression. Rectifying structural issues during the outline phase is preferable to addressing them after writing.

Remember to incorporate supporting evidence within the outline. Since there’s likely a substantial amount to include, outlining helps prevent overlooking crucial elements.

Writing The Introduction

According to the research paper format , the introduction of a research paper must address three fundamental inquiries: What, why, and how? Upon completing the introduction, the reader should clearly understand the paper’s subject matter, its relevance, and the approach you’ll use to construct your arguments.

What? Offer precise details regarding the paper’s topic, provide context, and elucidate essential terminology or concepts.

Why? This constitutes the most crucial yet challenging aspect of the introduction. Endeavour to furnish concise responses to the subsequent queries: What novel information or insights do you present? Which significant matters does your essay assist in defining or resolving?

How? To provide the reader with a preview of the paper’s forthcoming content, the introduction should incorporate a “guide” outlining the upcoming discussions. This entails briefly outlining the paper’s principal components in chronological sequence.

Developing The Main Body 

One of the primary challenges that many writers grapple with is effectively organizing the wealth of information they wish to present in their papers. This is precisely why an outline can be an invaluable tool. However, it’s essential to recognize that while an outline provides a roadmap, the writing process allows flexibility in determining the order in which information and arguments are introduced.

Maintaining cohesiveness throughout the paper involves anchoring your writing to the thesis statement and topic sentences. Here’s how to ensure a well-structured paper:

• Alignment with Thesis Statement: Regularly assess whether your topic sentences correspond with the central thesis statement. This ensures that your arguments remain on track and directly contribute to the overarching message you intend to convey.
• Consistency and Logical Flow: Review your topic sentences concerning one another. Do they follow a logical order that guides the reader through a coherent narrative? Ensuring a seamless flow from one topic to another helps maintain engagement and comprehension.
• Supporting Sentence Alignment: Each sentence within a paragraph should align with the topic sentence of that paragraph. This alignment reinforces the central idea, preventing tangential or disjointed discussions.

Additionally, identify paragraphs that cover similar content. While some overlap might be inevitable, it’s essential to approach shared topics from different angles, offering fresh insights and perspectives. Creating these nuanced differences helps present a well-rounded exploration of the subject matter.

An often-overlooked aspect of effective organization is the art of crafting smooth transitions. Transitions between sentences, paragraphs, and larger sections are the glue that holds your paper together. They guide the reader through the progression of ideas, enhancing clarity and creating a seamless reading experience.

Ultimately, while the struggle to organize information is accurate, employing these strategies not only aids in addressing the challenge but also contributes to the overall quality and impact of your writing.

Crafting A Strong Conclusion 

The purpose of the research paper’s conclusion is to guide your reader out of the realm of the paper’s argument, leaving them with a sense of closure.

Trace the paper’s trajectory, underscoring how all the elements converge to validate your thesis statement. Impart a sense of completion by ensuring the reader comprehends the resolution of the issues introduced in the paper’s introduction.

In addition, you can explore the broader implications of your argument, outline your paper’s contributions to future students studying the subject, and propose questions that your argument raises—ones that might not be addressed in the paper itself. However, it’s important to avoid:

• Introducing new arguments or crucial information that wasn’t covered earlier.
• Extending the conclusion unnecessarily.
• Employing common phrases that signal the decision (e.g., “In conclusion”).

By adhering to these guidelines, your conclusion can serve as a fitting and impactful conclusion to your research paper, leaving a lasting impression on your readers.

Refining The Research Paper

• Editing And Proofreading 

Eliminate unnecessary verbiage and extraneous content. In tandem with the comprehensive structure of your paper, focus on individual words, ensuring your language is robust. Verify the utilization of active voice rather than passive voice, and confirm that your word selection is precise and tangible.

The passive voice, exemplified by phrases like “I opened the door,” tends to convey hesitation and verbosity. In contrast, the active voice, as in “I opened the door,” imparts strength and brevity.

Each word employed in your paper should serve a distinct purpose. Strive to eschew the inclusion of surplus words solely to occupy space or exhibit sophistication.

For instance, the statement “The author uses pathos to appeal to readers’ emotions” is superior to the alternative “The author utilizes pathos to appeal to the emotional core of those who read the passage.”

Engage in thorough proofreading to rectify spelling, grammatical, and formatting inconsistencies. Once you’ve refined the structure and content of your paper, address any typographical and grammatical inaccuracies. Taking a break from your paper before proofreading can offer a new perspective.

Enhance error detection by reading your essay aloud. This not only aids in identifying mistakes but also assists in evaluating the flow. If you encounter sections that seem awkward during this reading, consider making necessary adjustments to enhance the overall coherence.

• Formatting And Referencing 

Citations are pivotal in distinguishing research papers from informal nonfiction pieces like personal essays. They serve the dual purpose of substantiating your data and establishing a connection between your research paper and the broader scientific community. Given their significance, citations are subject to precise formatting regulations; however, the challenge lies in the existence of multiple sets of rules.

It’s crucial to consult the assignment’s instructions to determine the required formatting style. Generally, academic research papers adhere to either of two formatting styles for source citations:

• MLA (Modern Language Association)
• APA (American Psychological Association)

Moreover, aside from MLA and APA styles, occasional demands might call for adherence to CMOS (The Chicago Manual of Style), AMA (American Medical Association), and IEEE (Institute of Electrical and Electronics Engineers) formats.

Initially, citations might appear intricate due to their numerous regulations and specific details. However, once you become adept at them, citing sources accurately becomes almost second nature. It’s important to note that each formatting style provides detailed guidelines for citing various sources, including photographs, websites, speeches, and YouTube videos.

Tips For Writing An Effective Research Paper 

By following these research paper writing tips , you’ll be well-equipped to create a well-structured, well-researched, and impactful research paper:

• Select a Clear and Manageable Topic: Choose a topic that is specific and focused enough to be thoroughly explored within the scope of your paper.

(Based on English Composition 2 from Illinois Valley Community College):

• Weak organization
• Poor support and development of ideas
• Weak use of secondary sources
• Excessive errors
• Stylistic weakness

When collecting materials, selecting research topic, and writing the paper:

• Be systematic and organized (e.g. keep your bibliography neat and organized; write your notes in a neat way, so that you can find them later on.
• Use your critical thinking ability when you read.
• Write down your thoughts (so that you can reconstruct them later).
• Stop when you have a really good idea and think about whether you could enlarge it to a whole research paper. If yes, take much longer notes.
• When you write down a quotation or summarize somebody else's thoughts in your notes or in the paper, cite the source (i.e. write down the author, title, publication place, year, page number).
• If you quote or summarize a thought from the internet, cite the internet source.
• Write an outline that is detailed enough to remind you about the content.
• Read your paper for yourself or, preferably, somebody else. 
• When you finish writing, check the spelling;
• Use the citation form (MLA, Chicago, or other) that your instructor requires and use it everywhere.

Plagiarism : somebody else's words or ideas presented without citation by an author

• Cite your source every time when you quote a part of somebody's work.
• Cite your source  every time when you summarize a thought from somebody's work.
• Cite your source  every time when you use a source (quote or summarize) from the Internet.

How to Write a Research Paper – A to Z of Academic Writing

Part of a scientist’s job is to publish research. In fact, some would argue that your experiment is only complete once you have published the results. This makes it available to the scientific community for authentication and the advancement of science. In addition, publishing is essential for a researcher’s career as it validates the research and opens doors for funding and employment. In this section, we give you a step-by-step guide to help you write an effective research paper. So, remember to set aside half an hour each day to write. This habit will make your writing manageable and keep you focused.

There are different types of research papers. The most common ones include:

Original research paper, rapid communication or letter, review article, meeting abstract, paper, and proceedings.

This is a full report written by researchers covering the analysis of their experimental study from start to finish. It is the most common type research manuscript that is published in academic journals. Original articles are expected to follow the IMRAD format.

These are usually written to publish results urgently in rapidly changing or highly competitive fields. They will be brief and may not be separated by headings.It consists of original preliminary results that are likely to have a significant impact in the respective field.

This is a comprehensive summary of a certain topic. It is usually requested by a journal editor and written by a leader in the field. It includes current assessment, latest findings, and future directions of the field. It is a massive undertaking in which approximately 100 research articles are cited. Uninvited reviews are published too, but it is best to send a pre-submission enquiry letter to the journal editor first.

This is mostly used in the medical field to report interesting occurrences such as previously unknown or emerging pathologies. It could be a report of a single case or multiple cases and will include a short introduction, methods, results, and discussion.

This is a brief report of research presented at an organized meeting such as a conference. These range from an abstract to a full report of the research. It needs to be focused and clear in explaining your topic and the main points of the study that will be shared with the audience.

How to Structure a Research Paper?

Your research paper should tell a story of how you began your research, what you found, and how it advances your research field. It is important to structure your research paper so that editors and readers can easily find information. The widely adopted structure that research papers mostly follow is the IMRaD format . IMRaD stands for Introduction, Methods, Results, and Discussion. Additional requirements from journals include an abstract, keywords, acknowledgements, and references. This format helps scientists to tell their story in an organized manner. Authors often find it easier to write the IMRaD sections in a different order. However, the final paper should be collated in the IMRaD format as follows:

Case studies follow a slightly different format to the traditional IMRAD format. They include the following extra sections:

• History and physical examination: Details of the patient’s history. It provides the story of when a patient first sought medical care.
• Diagnostic focus and assessment : Describe the steps taken that lead to a diagnosis and any test results.
• Therapeutic focus and assessment: Explain therapies tried and any other recommendations from consultants. Assess the efficacy of the treatments given.
• Follow-up and outcome: Provide results and state the patient adhered to treatment. Include any side effects.
• Patient perspective: Describe the patient’s experience.
• Patient consent: State that informed consent was obtained from the patient.

Order for Preparation of the Manuscript

As mentioned above, most research publications follow the IMRAD format. However, it is often easier to write each section in a different order than that of the final paper.

Authors recommend you organize the data first and then write the sections as follows:

• Figures and tables: Decide how your data should be presented. You can use graphics, tables or describe it in the text.
• Methods: It is important that anyone can use your methods to reproduce your experiments.
• Results: Here you write only what the results of your experiments were. You do not discuss them here.
• Discussion: This section requires analysis, thought, and a thorough understanding of the literature. You need to discuss your results without repeating the results section.
• Conclusion: This section can either be under a sub-heading or the last paragraph of the discussion. It should inform the reader how your results advance the field.
• Introduction: Now that you have thought about your results in the context of the literature, you can write your introduction.
• Abstract: This is an overview of your paper. Give a concise background of the problem and how you tried to solve it. Next state your main findings.
• Title: As discussed above, this needs to be concise as well as informative. Ensure that it makes sense.
• Keywords: These are used for indexing. Keywords need to be specific. Often you are not allowed to use words that appear in the journal name. Use abbreviations with care and only well-established ones.
• Acknowledgements: This section is to thank anyone involved in the research that does not qualify as an author.
• References: Check the “Guide for authors” for the formatting style. Be accurate and do not include unnecessary references.

How to Conceptualize an Attractive Research Paper Title?

Your research title is the first impression of your paper. A good research paper title is a brief description of the topic, method, sample, and results of your study. A useful formula you could use is:

There are different ways to write a research paper title :

Declarative

State the main conclusions. Example: Mixed strains of probiotics improve antibiotic associated diarrhea.

Descriptive

Describe the subject. Example: Effects of mixed strains of probiotics on antibiotic associated diarrhea.

Interrogative

Use a question for the subject. Example: Do mixed strains of probiotics improve antibiotic associated diarrhea?

We recommend the following five top tips to conceptualize an attractive research title:

• Be descriptive
• Use a low word count (5-15 words)
• Check journal guidelines
• Avoid jargon and symbols

How to Conduct an Effective Literature Review

The process of conducting a literature review can be overwhelming. However, if you start with a clear research question, you can stay focused.

• Literature search: Search for articles related to your research question. Keep notes of the search terms and keywords you use. A list of databases to search and notes of the ones you have searched will prevent duplicate searches.

- What is their research question?

- Are there potential conflicts of interest such as funders who may want a particular result?

- Are their methods sufficient to test the objectives?

- Can you identify any flaws in the research?

- Do their results make sense, or could there be other reasons for their conclusion?

- Are the authors respected in the field?

- Has the research been cited?

- Introduction: Here you introduce the topic. The introduction describes the problem and identifies gaps in knowledge. It also rationalizes your research.

- Discussion: Here you support and compare your results. Use the literature to put your research in context with the current state of knowledge. Furthermore, show how your research has advanced the field.

How to Write a Good Research Paper Abstract

The importance of research paper abstracts  cannot be emphasized enough.

• They are used by online databases to index large research works. Therefore, critical keywords must be used.
• Editors and reviewers read an abstract to decide whether an article is worth considering for publication.
• Readers use an abstract to decide whether the research is relevant to them.

A good research paper abstract is a concise and appealing synopsis of your research. There are two ways to write an abstract:  structured and unstructured research abstracts . The author guidelines of the journal you are submitting your research to will tell you the format they require.

• The structured abstract has distinct sections with headings. This style enables a reader to easily find the relevant information under clear headings (objective, methods, results, and conclusion). Think of each section as a question and provide a concise but detailed answer under each heading.
• The unstructured abstract is a narrative paragraph of your research. It is similar to the structured abstract but does not contain headings. It gives the context, findings, conclusion, and implications of your paper.

How to Write a Compelling Introduction for a Research Paper

The Introduction section of your research paper introduces your research  in the context of the knowledge in the field. First introduce the topic including the problem you are addressing, the importance of solving this problem, and known research and gaps in the knowledge. Then narrow it down to your research questions and hypothesis.

Tips to write an effective introduction for your research paper :

• Give broad background information about the problem.
• Write it in a logical manner so that the reader can follow your thought process.
• Focus on the problem you intend to solve with your research
• Note any solutions in the literature thus far.
• Propose your solution to the problem with reasons.

How to Write the Materials and Methods Section of a Research Paper

When writing the Materials and Methods section of a research paper, you need to give enough detail in your methods  so that others can reproduce your experiments. However, there is no need to detail established experiments. Readers can find these details in the previously published references you refer to in the methods. Follow these tips to write the Materials and Methods section of your research paper: :

• Write in the past tense because you are reporting on procedures you carried out.
• Avoid unnecessary details that disrupts the flow.
• Materials and equipments should be mentioned throughout the procedure, rather than listed at the beginning of a section.
• Detail any ethics or consent requirements if your study included humans or animal subjects.
• Use standard nomenclature and numbers.
• Ensure you have the correct control experiments.
• Methods should be listed logically.
• Detail statistical methods used to analyze your data.

Here is a checklist of things that should be in your Materials and Methods:

• References of previously published methods.
• Study settings : If the research involves studying a population, give location and context of the site.
• Cell lines : Give their source and detail any contamination tests performed.
• Antibodies : Give details such as catalogue numbers, citations, dilutions used, and batch numbers.
• Animal models : Species, age, and sex of animals as well as ethical compliance information.
• Human subjects : Ethics committee requirements and a statement confirming you received informed consent. If relevant, clinical trial registration numbers and selection criteria.
• Data accession codes for data you deposited in a repository.
• Software : Where you obtained the programs and their version numbers.
• Statistics : Criteria for including or excluding samples or subjects, randomisation methods, details of investigator blinding to avoid bias, appropriateness of statistical tests used for your study.
• Timeframes if relevant.

How to Write the Results Section of a Research Paper

Some journals combine the results and discussion section, whereas others have separate headings for each section. If the two sections are combined, you state the results of your research   and discuss them immediately afterwards, before presenting your next set of results.  The challenge is to present your data in a way that is logical and accurate. Set out your results in the same order as you set out your methods.

When writing the Results section of your research paper remember to include:

• Control group data.
• Relevant statistical values such as p-values.
• Visual illustrations of your results such as figures and tables.

Things that do not belong in the results section:

• Speculation or commentary about the results.
• References – you are reporting your own data.
• Do not repeat data in text if it has been presented in a table or graph.

Keep the discussion section separate . Keep explanations, interpretations, limitations, and comparisons to the literature for the discussion.

How to Write the Discussion Section of a Research Paper

The discussion section of your research paper answers several questions such as: did you achieve your objectives? How do your results compare to other studies? Were there any limitations to your research? Start discussing your data specifically and then broaden out to how it furthers your field of interest.

Questions to get you started:

• How do your results answer your objectives?
• Why do you think your results are different to published data?
• Do you think further research would help clarify any issues with your data?

The aim is to tell the reader what your results mean. Structure the discussion section of your research paper  in a logical manner. Start with an introductory paragraph where you set out the context and main aims of the study. Do this without repeating the introduction. Some authors prefer starting with the major findings first to keep the readers interested.

The next paragraph should discuss what you found, how it compares to other studies, any limitations, your opinion, and what they mean for the field.

The concluding paragraph should talk about the major outcomes of the study. Be careful not to write your conclusion here. Merely highlight the main themes emerging from your data.

Tips to write an effective discussion:

• It is not a literature review. Keep your comments relevant to your results.
• Interpret your results.
• Be concise and remove unnecessary words.
• Do not include results not presented in the result section.
• Ensure your conclusions are supported by your data.

How to Write the Conclusion of a Research Paper

While writing the conclusion for your research paper, give a summary of your research with emphasis on your findings. Again, structuring the conclusion section of your research paper  will make it easier to draft this section. Here are some tips when writing the conclusion of your paper:

• State what you set out to achieve.
• Tell the reader what your major findings were.
• How has your study contributed to the field?
• Mention any limitations.
• End with recommendations for future research.

Effectively Citing and Referencing Your Sources

You need to acknowledge the original work  that you talk about in your write-up. There are two reasons for this. First, cite someone’s idea  to avoid plagiarism. Plagiarism is when you use words or ideas of others without acknowledging them and this is a serious offence. Second, readers will be able to source the literature you cited easily.

This is done by citing works  in your text and providing the full reference for this citation in a reference list at the end of your document.

Tips for effective refencing/citations:

• Keep a detailed list of your references including author(s), publication, year of publication, title, and page numbers.
• Insert a citation (either a number or author name) in-text as you write.
• List the full reference in a reference list according to the style required by the publication.
• Pay attention to details as mistakes will misdirect readers.

Try referencing software tools “cite while you write”. Examples of such referencing software programs include: Mendeley , Endnote , Refworks  and Zotero .

Preparing Figures

Some quick tips about figures:

• Legends of graphs and tables must be self-explanatory.
• Use easily distinguishable symbols.
• Place long tables of data in the supplementary material.
• Include a scale bar in photographs.

Preparing Tables

Important pointers for tables:

• Check the author guidelines for table formatting requirements.
• Tables do not have vertical lines in publications.
• Legends must be self-explanatory.

Assigning Authorship

To qualify as an author  on a paper, an individual must:

• Make substantial contributions to all stages of the research.
• Draft or revise the manuscript.
• Approve the final version of the article.
• Be accountable for the accuracy and integrity of the research.

Unethical and unprofessional authorships  have emerged over the years. These include:

• Gift authorship : An individual is listed as a co-author in lieu of funding or supervision.
• Ghost authorship : An author is paid to write an article but does not contribute to the article in any other way.
• Guest authorship : An individual who is given authorship because they are well known and respected in the field, or they are senior members of staff.

These authors pose a threat to research. Readers may override their concerns with an article if it includes a well-respected co-author. This is especially problematic when decisions about medical interventions are concerned.

How to Write an Acknowledgment Section for a Research Paper

Those who do not qualify as authors but have contributed to the research should be given credit in the acknowledgements section of your research paper . These include funders, supervisors, administrative supporters, writing, editing, and proofreading assistance .

The contributions made by these individuals should be stated and sometimes their written permission to be acknowledged is required by editors.

Points to Note from the Author Instructions Before Preparing the Manuscript

Check the author guidelines for your chosen publication before submission. Publishers mostly have a “House Style” that ensures all their manuscripts are consistent with regards to language, formatting, and style. For example, these guidelines will tell you whether to use UK or US English, which abbreviations are allowed, and how to format figures and tables. They are also especially important for the references section as each journal has their own style.

Proofreading/Editing your Manuscript

Ensure that your manuscript is structured correctly, clearly written, contains the correct technical language, and supports your claims with proper evidence. To ensure the structure is correct, it is essential to edit your paper .

Once you are happy with the manuscript, proofread for small errors. These could be spelling, consistency, spacing, and so forth. Importantly, check that figures and tables include all the necessary data and statistical values. Seek assistance from colleagues or professional editing companies to edit and proofread your manuscript too.

Pre-submission Peer-Review of Your Manuscript

A pre-submission peer-review  could improve the quality of articles submitted to journals in general. The benefits include:

• A fresh eye to spot gaps or errors.
• Receiving constructive feedback on your work and writing.
• Improves the clarity of your paper.

You could ask experienced colleagues, supervisors or even professional editing services to review your article.

How To Write a Research Paper: The Ultimate Guide

UOTP Marketing

Regardless of the degree or program, you enroll in, writing research papers is inevitable. The process can seem daunting due to the time and effort it takes. But with the proper approach, you’ll make it. 

This article will guide you on how to write a research paper perfectly, including how to write a thesis statement for a research paper, how to write a conclusion for a research paper, etc. More specifically, there are nine steps you need to follow to pave the way to a successfully written research paper.

But before that, let’s learn what a research paper is.

What Is a Research Paper?

A research paper can be considered an extended version of an essay . The research paper aims to present your interpretation, argument, or evaluation. In contrast to essays, research papers are more complex and require deep research on a particular matter. Research papers are characterized by the inclusivity of the presentation of other scientists’ opinions.

A research paper is more than a summary, collection of other sources, or literature review. At its core, the research paper analyzes and argues your point of view, further backed up by other studies. 

Completing a research paper is a challenging task. But, with our help, you can start and build your way to a good end. Let’s get started!

How To Write a Research Paper

Writing a research paper sounds easy; you pick the topic, develop your argument, research what other studies have said, and conclude it. Those are the general rules. But writing a successful research paper requires you to be more attentive, consistent, and detailed. 

The following steps will guide you through a more detailed process of writing a research paper. 

Get familiar with the assignment

Writing a research paper takes more than just listening to the instruction while your professor explains. Because many students are not cautious enough to carefully listen and analyze every given step, they end up with a poorly graded assignment or, in the worst case, even fail. 

Spend some time reading every instruction, and when in doubt, ask questions! Professors are always open to answering any questions you might have.

Choose a topic for your research paper

Deciding on a topic is usually time-consuming since there are so many topics available. If you need help deciding on a topic, think about what you are passionate about, but always remember to stay within the lines of the instructions. When choosing a topic, keep the following in mind:

• Choose a topic relevant to the length of the paper: If your professor has instructed a longer paper than usual, keep your topic broad, for example, “Internships.” On the other hand, if it’s shorter, try to narrow your topic to something more specific such as “Internship’s impact on interpersonal skills.”
• Consider topics that allow you to discuss or analyze rather than summarize: If you’re writing anything literature related, focus on how, for example, a particular scene leads to a specific theme. Avoid choosing a topic that plainly describes scenes or characters. 
• Find a topic with many previous studies available: Since research papers mainly focus on your research, you must ensure plenty of studies can support your arguments.

Do the research and take notes

Now it’s time to research what different scholars have written about the topic. Since this step requires a lot of reading and comprehension, it’s crucial to know how to read scholarly articles effectively and efficiently. The pieces you will go through will be lengthy, and sometimes only a few parts within those papers will be helpful. That’s why it is essential to skim and scan. 

Secondly, find reliable sources. Visit sites such as Google Scholar, and focus on peer-reviewed articles since they contain information that has been reviewed and evaluated. 

Next, keep track of what you have read so far. It’s vital to save everything you have read and consider influential in one place. Instead of going back and forth between different sites, you can have everything in one place. You can bookmark the sources or link those sources to a document. That will save you valuable time when you start writing. 

And remember: always stay focused and within your topic area.

Formulate your thesis statement

Research until you reach your own opinion or argument on the topic, otherwise known as a thesis statement. A thesis statement is an introductory statement that puts forward your explanation or point within the paper. When formulating a thesis statement, remember the following:

• Don’t be vague.
• Make a strong statement.
• Make it arguable.

Checking in with your professor after you have developed a clear, persuasive thesis statement can be helpful. Ask them whether they agree your thesis statement is the right one. And if you get a positive answer, you’re ready for the next step.

Create an outline for your research paper

Even if it’s not required by your instructor, creating an outline will help you greatly in the long run. A structure will simplify the writing process, regardless of length or complexity. It should contain detailed information for the arrangement of each paragraph and identify the smaller components per each paragraph in order, such as the introductory sentence and the supporting evidence. 

The outline will create a visual board and help you define what to include and where. And most importantly, in this part, you can identify possible mistakes and not have them in your drafts.

Write your first draft

And now you’ve made it to the real deal. The work you’ve done till this point matters a lot. If you succeed in having a good topic, a strong thesis with backup evidence, and an already structured paper, half of the job is already done—you just have to fill in the blanks at this point. 

As you first start writing, remember that this is the first draft. Trust your memory and avoid going between sources and your paper. This way, you can prevent plagiarism and be original instead. Start with the introduction and the body, and work through a conclusion.

Introduction

Introductions to research papers are always unique. It is the part where you set up the topic and hook your reader. Additionally, you must provide background to the existing research, position your approach, and put forward the thesis statement. Furthermore, you need to explain why your topic deserves immediate attention.

An introduction highlights all you’ve gathered from your research. While it may seem fine to write the introduction first, we suggest you focus on the body of the paper first. Then you’ll find it simple to build a clear summary.

This is the longest part of the research paper. You are required to support your thesis and build the argument, followed by citations and analysis.

Place the paragraphs in a logical arrangement so each key point flows naturally to the next one. Similarly, organize the sentences in each paragraph in an organic structure. If you have carefully arranged your notes and created an outline, your thoughts will automatically fall into place when you write your draft.

After introducing your topic and arguing your points, the conclusion will bring everything together. Focus on developing a stimulating and informative conclusion. Make it possible for readers to understand it independently from the rest of the paper.

These are some of the suggestions that will lead to a well-written conclusion:

• Provide a clear summary 
• Emphasize issues raised and possible solutions

Write your second draft

Usually, the first draft is followed by a second one. However, before proceeding with the process, highlight the errors and points you would prefer to avoid including in the final draft. With the help of a second draft, you will be able to notice mistakes and create a definitive outline for the final draft. Furthermore, you can communicate your ideas more clearly and effectively by creating multiple drafts.

Cite sources and prepare a bibliography

Citations are what characterize the research paper. The importance of citations lies in reliability: citing sources will make your writing more reliable. But how do you cite correctly? The problem is that there is more than just a set of rules. If your professor has set no rules, you can ask them. After being given the right instructions on what citation style to use, do plenty of research and make sure to cite correctly. 

Edit, edit, and edit some more

Now it’s time to strive for perfection. Start editing with a fresh perspective. Firstly, focus on the content. It would be beneficial to create a checklist you can follow. You can produce a list that follows the instructions of your professor. If everything checks right, you can submit it. Otherwise, you’ll need to work toward perfecting the paper. Here are some things you need to check: 

• Are you within the lines of the assignment?
• Have you achieved the right length? 
• Do sentences communicate your ideas? 
• Is the supporting evidence conducted correctly?

It is also crucial to edit for grammar. Plenty of online tools, such as Grammarly and Hemingway Editor, can help you during the process. You can also ask your peers to check it after you’ve done your part. Their fresh perspective will pick up on many things you might have missed.

The Bottom Line

Writing a research paper is one of the essential parts of academics. The process might seem straightforward, but there are many steps you should carefully follow. And remember: always stay on track with your progress; otherwise, you will get lost in tasks. 

We hope by the time you have read this guide, you’ve been able to pick up the essential parts. But if you haven’t, you can go through it again.

Writing a Research Paper

Welcome to the Purdue OWL

The pages in this section provide detailed information about how to write research papers including discussing research papers as a genre, choosing topics, and finding sources.

The Research Paper

There will come a time in most students' careers when they are assigned a research paper. Such an assignment often creates a great deal of unneeded anxiety in the student, which may result in procrastination and a feeling of confusion and inadequacy. This anxiety frequently stems from the fact that many students are unfamiliar and inexperienced with this genre of writing. Never fear—inexperience and unfamiliarity are situations you can change through practice! Writing a research paper is an essential aspect of academics and should not be avoided on account of one's anxiety. In fact, the process of writing a research paper can be one of the more rewarding experiences one may encounter in academics. What is more, many students will continue to do research throughout their careers, which is one of the reasons this topic is so important.

Becoming an experienced researcher and writer in any field or discipline takes a great deal of practice. There are few individuals for whom this process comes naturally. Remember, even the most seasoned academic veterans have had to learn how to write a research paper at some point in their career. Therefore, with diligence, organization, practice, a willingness to learn (and to make mistakes!), and, perhaps most important of all, patience, students will find that they can achieve great things through their research and writing.

The pages in this section cover the following topic areas related to the process of writing a research paper:

• Genre - This section will provide an overview for understanding the difference between an analytical and argumentative research paper.
• Choosing a Topic - This section will guide the student through the process of choosing topics, whether the topic be one that is assigned or one that the student chooses themselves.
• Identifying an Audience - This section will help the student understand the often times confusing topic of audience by offering some basic guidelines for the process.
• Where Do I Begin - This section concludes the handout by offering several links to resources at Purdue, and also provides an overview of the final stages of writing a research paper.

How to write a research paer

Understand the topic, what is the instructor asking for, who is the intended audience, choosing a topic.

• General Research

Books on the subject

Journal articles, other sources, write the paper.

You've just been assigned by your instructor to write a paper on a topic. Relax, this isn't going to be as bad as it seems. You just need to get started. Here are some suggestions to make the process as painless as possible. Remember, if you have any questions ASK .

Is the assignment a formal research paper where you have to do research and cite other sources of information, or is the assignment asking you for your reaction to a particular topic where all you will need to do is collect your thoughts and organize them coherently. If you do need to research your topic, make sure you know what style manual your instructor prefers (MLA, APA, Chicago, etc).

Make sure you keep track of any restrictions that your instructor places on you. If your instructor wants a 4 page paper, they won't be happy with a 2 page paper, or a 10 page paper. Keep in mind that the instructor knows roughly how long it should take to cover the topic. If your paper is too short, you probably aren't looking at enough materials. If you paper is too long, you need to narrow your topic. Also, many times the instructor may restrict you to certain types of resources (books written after 1946, scholarly journals, no web sites). You don't want to automatically lessen your grade by not following the rules. Remember the key rule, if you have any questions ask your instructor!

You will also need to know which audience that you are writing for. Are you writing to an audience that knows nothing about your topic? If so you will need to write in such a way that you paper makes sense, and can be understood by these people. If your paper is geared to peers who have a similar background of information you won't need to include that type of information. If your paper is for experts in the field, you won't need to include background information.

If you're lucky, you were given a narrow topic by your instructor. You may not be interested in your topic, but you can be reasonably sure that the topic isn't too broad. Most of you aren't going to be that lucky. Your instructor gave you a broad topic, or no topic at all and you are going to have to choose the specific topic for your paper.

There are some general rules that you can use to help choose and narrow a topic. Does a particular topic interest you? If you are excited by a particular field, choose a topic from that field. While doing research you will learn more about the field, and learn which journals are written for your topic. Are you answering a relevant question? You and your instructor are going to be bored if you are writing a paper on the hazards of drunken driving. However, it might be more interesting to write about what causes people to drink and drive. The more interesting your topic the more you will enjoy and learn from writing your paper. You may also want to focus on a specific point of view about the topic, such as what teenagers think the causes of drunken driving are.

Do General Research

Now that you have a topic, it is time to start doing research. Don't jump to the card catalog and the indexes yet. The first research that you want to do is some general research on your topic. Find out what some of the terms used in the field are. You will also find that this research can help you further define you topic.

One source of general research is a general encyclopedia. Depending on the encyclopedia, at the end of each entry there may be a bibliography of suggested works. Good encyclopedias to consult are Encyclopedia Britannica , Encyclopedia Americana, and World Book.

You will also want to check to see if your topic is in a field that has a subject Encyclopedia, a Subject Handbook, or a Subject Dictionary. These guides contain information about a wide variety of topics inside a specific field. Generally the information in more detailed that what is contained in a general encyclopedia. Also the bibliographies are more extensive.

Find further information

Now that we have some background information on our topic; we need to find information about our specific topic. Before searching, ask yourself what type of information you are looking for. If you want to find statistical information, you will need to look in certain types of sources. If you are looking for news accounts of an event, you will need to look in other types of sources. Remember, if you have a question about what type of source to use, ask a librarian.

Have you asked your instructor for suggestions on where to look? Why not? This person is experienced in the field, and they have been doing research in it longer than you have. They can recommend authors who write on your topic, and they can recommend a short list of journals that may contain information on your topic.

Books are one type of resource that you can use for your research. To find a book on your topic, you will need to use the online catalog, the CamelCat . Taking the list of keywords that you created while doing general research, do keyword searches in the catalog. Look at the titles that are being returned, do any look promising? If none do, revise your search using other keywords. If one does, look at the full record for that book. Check the subject headings that it is cataloged by. If one of those headings looks pertinent to your research, do a subject search using that particular heading.

Once you've got the books that you want to use start evaluating whether the book will be useful. Is it written by an author who is knowledgeable about that particular topic? Is the author qualified to write about the topic? What biases does the author have about the topic? Is the book current enough to contain useful information?

Once you've answered these questions, use the books that you deem useful for your research. Remember while taking notes to get the information that you need to do a proper citation. Also, pay attention to any bibliographies that are included in the book. These can help you locate other books and articles that may be useful for your research.

The Campbell University Libraries subscribe to a wide variety of Indexes and Journals for the use of students and faculty. Increasingly these materials are provided as Electronic Databases. These databases contain citations of articles and in some cases the full text of articles on a variety of topics. If you don't know which database will be useful for you, ask a librarian and they will be happy to assist you. You can also use the Find Articles link to search multiple databases at one time for information on your topic.

Once you've selected a database to use, use the keywords that you developed from your general research to find articles that will be useful for you. Once you've found one, see which terms the database used to catalog the article and use those terms to find more articles. Don't forget to set limits on the database so that only scholarly articles are returned if your instructor has made that a requirement for your paper.

Look at the journal articles that you have selected, and examine the bibliographies. Are there any authors that are mentioned in more than one article? Are there any articles that are mentioned more than once? You should find those authors and articles and include them in your research.

There are other useful sources that you can use in your research. If your report tends to be on a business topic or if you need company information for your research there are many companies that provide company reports. The contents of these reports differ, depending on which service that you are using. Generally speaking you will find company officers, financial statements, lists of competitors, and stock price.

The Internet is another source for information on a variety of topics. The major problem with the using Internet resources is authority. Anybody who knows HTML can produce a web site that looks pretty decent. However, a website produced by a sophomore in high school on a topic is not going to be useful to you in your research. Before using a website for information, you need to evaluate the site. Here are some questions you will want to ask: Who created the site? (If you can't tell, don't use it.) Has the site been recently updated? Is the site promoting a specific agenda/ does it have a bias? (Bias isn't necessarily bad, but you need to keep it in mind when interpreting the information presented?) Are there any misspellings on the site? (If there is one misspelling careless error more than three, don't use the page) Do the links on the page work? (If a few don't work, not a big problem, if most of the links don't work, the site isn't being maintained, and should not be used.)

You have all of your research, now it is time to write the paper. Don't forget to cite all of the research that you have collected using the preferred citation style of your instructor. If possible try to give yourself a couple of days to let the paper sit before you edit it. Look at a hard copy of the paper and check for mechanical errors (spelling, punctuation). Also try to imagine that you are the intended audience for the paper. Does your paper make sense? Are the arguments logical? Does the evidence presented support the arguments made? If you answered no to any of these questions, make the necessary changes to your paper.

13.1 Formatting a Research Paper

Learning objectives.

• Identify the major components of a research paper written using American Psychological Association (APA) style.
• Apply general APA style and formatting conventions in a research paper.

In this chapter, you will learn how to use APA style , the documentation and formatting style followed by the American Psychological Association, as well as MLA style , from the Modern Language Association. There are a few major formatting styles used in academic texts, including AMA, Chicago, and Turabian:

• AMA (American Medical Association) for medicine, health, and biological sciences
• APA (American Psychological Association) for education, psychology, and the social sciences
• Chicago—a common style used in everyday publications like magazines, newspapers, and books
• MLA (Modern Language Association) for English, literature, arts, and humanities
• Turabian—another common style designed for its universal application across all subjects and disciplines

While all the formatting and citation styles have their own use and applications, in this chapter we focus our attention on the two styles you are most likely to use in your academic studies: APA and MLA.

If you find that the rules of proper source documentation are difficult to keep straight, you are not alone. Writing a good research paper is, in and of itself, a major intellectual challenge. Having to follow detailed citation and formatting guidelines as well may seem like just one more task to add to an already-too-long list of requirements.

Following these guidelines, however, serves several important purposes. First, it signals to your readers that your paper should be taken seriously as a student’s contribution to a given academic or professional field; it is the literary equivalent of wearing a tailored suit to a job interview. Second, it shows that you respect other people’s work enough to give them proper credit for it. Finally, it helps your reader find additional materials if he or she wishes to learn more about your topic.

Furthermore, producing a letter-perfect APA-style paper need not be burdensome. Yes, it requires careful attention to detail. However, you can simplify the process if you keep these broad guidelines in mind:

• Work ahead whenever you can. Chapter 11 “Writing from Research: What Will I Learn?” includes tips for keeping track of your sources early in the research process, which will save time later on.
• Get it right the first time. Apply APA guidelines as you write, so you will not have much to correct during the editing stage. Again, putting in a little extra time early on can save time later.
• Use the resources available to you. In addition to the guidelines provided in this chapter, you may wish to consult the APA website at http://www.apa.org or the Purdue University Online Writing lab at http://owl.english.purdue.edu , which regularly updates its online style guidelines.

General Formatting Guidelines

This chapter provides detailed guidelines for using the citation and formatting conventions developed by the American Psychological Association, or APA. Writers in disciplines as diverse as astrophysics, biology, psychology, and education follow APA style. The major components of a paper written in APA style are listed in the following box.

These are the major components of an APA-style paper:

Body, which includes the following:

• Headings and, if necessary, subheadings to organize the content
• In-text citations of research sources
• References page

All these components must be saved in one document, not as separate documents.

The title page of your paper includes the following information:

• Title of the paper
• Author’s name
• Name of the institution with which the author is affiliated
• Header at the top of the page with the paper title (in capital letters) and the page number (If the title is lengthy, you may use a shortened form of it in the header.)

List the first three elements in the order given in the previous list, centered about one third of the way down from the top of the page. Use the headers and footers tool of your word-processing program to add the header, with the title text at the left and the page number in the upper-right corner. Your title page should look like the following example.

The next page of your paper provides an abstract , or brief summary of your findings. An abstract does not need to be provided in every paper, but an abstract should be used in papers that include a hypothesis. A good abstract is concise—about one hundred fifty to two hundred fifty words—and is written in an objective, impersonal style. Your writing voice will not be as apparent here as in the body of your paper. When writing the abstract, take a just-the-facts approach, and summarize your research question and your findings in a few sentences.

In Chapter 12 “Writing a Research Paper” , you read a paper written by a student named Jorge, who researched the effectiveness of low-carbohydrate diets. Read Jorge’s abstract. Note how it sums up the major ideas in his paper without going into excessive detail.

Write an abstract summarizing your paper. Briefly introduce the topic, state your findings, and sum up what conclusions you can draw from your research. Use the word count feature of your word-processing program to make sure your abstract does not exceed one hundred fifty words.

Depending on your field of study, you may sometimes write research papers that present extensive primary research, such as your own experiment or survey. In your abstract, summarize your research question and your findings, and briefly indicate how your study relates to prior research in the field.

Margins, Pagination, and Headings

APA style requirements also address specific formatting concerns, such as margins, pagination, and heading styles, within the body of the paper. Review the following APA guidelines.

Use these general guidelines to format the paper:

• Set the top, bottom, and side margins of your paper at 1 inch.
• Use double-spaced text throughout your paper.
• Use a standard font, such as Times New Roman or Arial, in a legible size (10- to 12-point).
• Use continuous pagination throughout the paper, including the title page and the references section. Page numbers appear flush right within your header.
• Section headings and subsection headings within the body of your paper use different types of formatting depending on the level of information you are presenting. Additional details from Jorge’s paper are provided.

Begin formatting the final draft of your paper according to APA guidelines. You may work with an existing document or set up a new document if you choose. Include the following:

• Your title page
• The abstract you created in Note 13.8 “Exercise 1”
• Correct headers and page numbers for your title page and abstract

APA style uses section headings to organize information, making it easy for the reader to follow the writer’s train of thought and to know immediately what major topics are covered. Depending on the length and complexity of the paper, its major sections may also be divided into subsections, sub-subsections, and so on. These smaller sections, in turn, use different heading styles to indicate different levels of information. In essence, you are using headings to create a hierarchy of information.

The following heading styles used in APA formatting are listed in order of greatest to least importance:

• Section headings use centered, boldface type. Headings use title case, with important words in the heading capitalized.
• Subsection headings use left-aligned, boldface type. Headings use title case.
• The third level uses left-aligned, indented, boldface type. Headings use a capital letter only for the first word, and they end in a period.
• The fourth level follows the same style used for the previous level, but the headings are boldfaced and italicized.
• The fifth level follows the same style used for the previous level, but the headings are italicized and not boldfaced.

Visually, the hierarchy of information is organized as indicated in Table 13.1 “Section Headings” .

Table 13.1 Section Headings

A college research paper may not use all the heading levels shown in Table 13.1 “Section Headings” , but you are likely to encounter them in academic journal articles that use APA style. For a brief paper, you may find that level 1 headings suffice. Longer or more complex papers may need level 2 headings or other lower-level headings to organize information clearly. Use your outline to craft your major section headings and determine whether any subtopics are substantial enough to require additional levels of headings.

Working with the document you developed in Note 13.11 “Exercise 2” , begin setting up the heading structure of the final draft of your research paper according to APA guidelines. Include your title and at least two to three major section headings, and follow the formatting guidelines provided above. If your major sections should be broken into subsections, add those headings as well. Use your outline to help you.

Because Jorge used only level 1 headings, his Exercise 3 would look like the following:

Citation Guidelines

In-text citations.

Throughout the body of your paper, include a citation whenever you quote or paraphrase material from your research sources. As you learned in Chapter 11 “Writing from Research: What Will I Learn?” , the purpose of citations is twofold: to give credit to others for their ideas and to allow your reader to follow up and learn more about the topic if desired. Your in-text citations provide basic information about your source; each source you cite will have a longer entry in the references section that provides more detailed information.

In-text citations must provide the name of the author or authors and the year the source was published. (When a given source does not list an individual author, you may provide the source title or the name of the organization that published the material instead.) When directly quoting a source, it is also required that you include the page number where the quote appears in your citation.

This information may be included within the sentence or in a parenthetical reference at the end of the sentence, as in these examples.

Epstein (2010) points out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).

Here, the writer names the source author when introducing the quote and provides the publication date in parentheses after the author’s name. The page number appears in parentheses after the closing quotation marks and before the period that ends the sentence.

Addiction researchers caution that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (Epstein, 2010, p. 137).

Here, the writer provides a parenthetical citation at the end of the sentence that includes the author’s name, the year of publication, and the page number separated by commas. Again, the parenthetical citation is placed after the closing quotation marks and before the period at the end of the sentence.

As noted in the book Junk Food, Junk Science (Epstein, 2010, p. 137), “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive.”

Here, the writer chose to mention the source title in the sentence (an optional piece of information to include) and followed the title with a parenthetical citation. Note that the parenthetical citation is placed before the comma that signals the end of the introductory phrase.

David Epstein’s book Junk Food, Junk Science (2010) pointed out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).

Another variation is to introduce the author and the source title in your sentence and include the publication date and page number in parentheses within the sentence or at the end of the sentence. As long as you have included the essential information, you can choose the option that works best for that particular sentence and source.

Citing a book with a single author is usually a straightforward task. Of course, your research may require that you cite many other types of sources, such as books or articles with more than one author or sources with no individual author listed. You may also need to cite sources available in both print and online and nonprint sources, such as websites and personal interviews. Chapter 13 “APA and MLA Documentation and Formatting” , Section 13.2 “Citing and Referencing Techniques” and Section 13.3 “Creating a References Section” provide extensive guidelines for citing a variety of source types.

Writing at Work

APA is just one of several different styles with its own guidelines for documentation, formatting, and language usage. Depending on your field of interest, you may be exposed to additional styles, such as the following:

• MLA style. Determined by the Modern Languages Association and used for papers in literature, languages, and other disciplines in the humanities.
• Chicago style. Outlined in the Chicago Manual of Style and sometimes used for papers in the humanities and the sciences; many professional organizations use this style for publications as well.
• Associated Press (AP) style. Used by professional journalists.

References List

The brief citations included in the body of your paper correspond to the more detailed citations provided at the end of the paper in the references section. In-text citations provide basic information—the author’s name, the publication date, and the page number if necessary—while the references section provides more extensive bibliographical information. Again, this information allows your reader to follow up on the sources you cited and do additional reading about the topic if desired.

The specific format of entries in the list of references varies slightly for different source types, but the entries generally include the following information:

• The name(s) of the author(s) or institution that wrote the source
• The year of publication and, where applicable, the exact date of publication
• The full title of the source
• For books, the city of publication
• For articles or essays, the name of the periodical or book in which the article or essay appears
• For magazine and journal articles, the volume number, issue number, and pages where the article appears
• For sources on the web, the URL where the source is located

The references page is double spaced and lists entries in alphabetical order by the author’s last name. If an entry continues for more than one line, the second line and each subsequent line are indented five spaces. Review the following example. ( Chapter 13 “APA and MLA Documentation and Formatting” , Section 13.3 “Creating a References Section” provides extensive guidelines for formatting reference entries for different types of sources.)

In APA style, book and article titles are formatted in sentence case, not title case. Sentence case means that only the first word is capitalized, along with any proper nouns.

Key Takeaways

• Following proper citation and formatting guidelines helps writers ensure that their work will be taken seriously, give proper credit to other authors for their work, and provide valuable information to readers.
• Working ahead and taking care to cite sources correctly the first time are ways writers can save time during the editing stage of writing a research paper.
• APA papers usually include an abstract that concisely summarizes the paper.
• APA papers use a specific headings structure to provide a clear hierarchy of information.
• In APA papers, in-text citations usually include the name(s) of the author(s) and the year of publication.
• In-text citations correspond to entries in the references section, which provide detailed bibliographical information about a source.

A Beginner's Guide to Starting the Research Process

When you have to write a thesis or dissertation , it can be hard to know where to begin, but there are some clear steps you can follow.

The research process often begins with a very broad idea for a topic you’d like to know more about. You do some preliminary research to identify a  problem . After refining your research questions , you can lay out the foundations of your research design , leading to a proposal that outlines your ideas and plans.

This article takes you through the first steps of the research process, helping you narrow down your ideas and build up a strong foundation for your research project.

Table of contents

Step 1: choose your topic, step 2: identify a problem, step 3: formulate research questions, step 4: create a research design, step 5: write a research proposal, other interesting articles.

First you have to come up with some ideas. Your thesis or dissertation topic can start out very broad. Think about the general area or field you’re interested in—maybe you already have specific research interests based on classes you’ve taken, or maybe you had to consider your topic when applying to graduate school and writing a statement of purpose .

Even if you already have a good sense of your topic, you’ll need to read widely to build background knowledge and begin narrowing down your ideas. Conduct an initial literature review to begin gathering relevant sources. As you read, take notes and try to identify problems, questions, debates, contradictions and gaps. Your aim is to narrow down from a broad area of interest to a specific niche.

Make sure to consider the practicalities: the requirements of your programme, the amount of time you have to complete the research, and how difficult it will be to access sources and data on the topic. Before moving onto the next stage, it’s a good idea to discuss the topic with your thesis supervisor.

So you’ve settled on a topic and found a niche—but what exactly will your research investigate, and why does it matter? To give your project focus and purpose, you have to define a research problem .

The problem might be a practical issue—for example, a process or practice that isn’t working well, an area of concern in an organization’s performance, or a difficulty faced by a specific group of people in society.

Alternatively, you might choose to investigate a theoretical problem—for example, an underexplored phenomenon or relationship, a contradiction between different models or theories, or an unresolved debate among scholars.

To put the problem in context and set your objectives, you can write a problem statement . This describes who the problem affects, why research is needed, and how your research project will contribute to solving it.

>>Read more about defining a research problem

Next, based on the problem statement, you need to write one or more research questions . These target exactly what you want to find out. They might focus on describing, comparing, evaluating, or explaining the research problem.

A strong research question should be specific enough that you can answer it thoroughly using appropriate qualitative or quantitative research methods. It should also be complex enough to require in-depth investigation, analysis, and argument. Questions that can be answered with “yes/no” or with easily available facts are not complex enough for a thesis or dissertation.

In some types of research, at this stage you might also have to develop a conceptual framework and testable hypotheses .

>>See research question examples

The research design is a practical framework for answering your research questions. It involves making decisions about the type of data you need, the methods you’ll use to collect and analyze it, and the location and timescale of your research.

There are often many possible paths you can take to answering your questions. The decisions you make will partly be based on your priorities. For example, do you want to determine causes and effects, draw generalizable conclusions, or understand the details of a specific context?

You need to decide whether you will use primary or secondary data and qualitative or quantitative methods . You also need to determine the specific tools, procedures, and materials you’ll use to collect and analyze your data, as well as your criteria for selecting participants or sources.

>>Read more about creating a research design

Receive feedback on language, structure, and formatting

Professional editors proofread and edit your paper by focusing on:

• Academic style
• Vague sentences
• Style consistency

See an example

Finally, after completing these steps, you are ready to complete a research proposal . The proposal outlines the context, relevance, purpose, and plan of your research.

As well as outlining the background, problem statement, and research questions, the proposal should also include a literature review that shows how your project will fit into existing work on the topic. The research design section describes your approach and explains exactly what you will do.

You might have to get the proposal approved by your supervisor before you get started, and it will guide the process of writing your thesis or dissertation.

How to write a research paper | A Proven Approach

Students are asked to write a research paper at the college or university level. Do you know how to write a research paper? Many students find it difficult to even begin working on such a piece of writing. But why? Why do students find research papers so scary? This is because it involves multiple processes. It is much more complex than a typical high school or college essay . This blog will show you how to write a research paper. But first, it's important to understand what a research paper is before getting into too much detail.

What is a research paper?

Here is the research paper meaning: A research paper is a large piece of academic document that is based on the research of the author. The goal of writing a research paper is to show your understanding of a topic or to deliver new results based on the research done.  Scholars from academia compile data from previously finished research projects. In the research paper, the author compiles evidence in favour of or against the thesis. Its aim is to contribute knowledge, answer questions, or solve problems, helping others understand and build upon the existing information in a particular field.

How to Write a Research Paper in a few simple steps?

If you’re wondering how do you write a research paper? Here is a simple guide to writing a research paper specially designed for students. From selecting a topic to organizing your research, we’ve covered everything. By following these research paper guidelines, you can easily generate an excellent piece of paper.

Understand the assignment 

Unbelievably, a lot of students start writing research papers without even reading the instructions. Even though some people may already know this, it's crucial to highlight how important it is to read the rules thoroughly before beginning.

To start, carefully read the instructions and topic. Note down any technical requirements given, such as paper length, word count, formatting rules, or citation style. Furthermore, pay attention to details, such as whether an abstract or a cover page is required or not.

Once you have a clear understanding of all requirements, proceed with the writing stage. Despite the fact that research papers follow certain guidelines, you can follow the regular writing procedure with a few extra steps. However, the basic structure of the writing process doesn't change.

For example, let's talk about a hypothetical scenario where a student named James is asked to write a research paper on climate change. Before start the writing process, James carefully read and understood the assignment details. The instructions say that James's paper about climate change should:

• Follow APA formatting guidelines.
• Be 10-12 pages long.
• Include at least ten academic sources.
• Have a cover page.
• Include an abstract.

With these instructions in mind, James now has a solid point to start his writing process. He can proceed by doing detailed research. He has to gather accurate sources and arrange his findings. James can polish his thoughts and arguments by adhering to the conventional writing process of drafting, revising, and editing, resulting in a work that is well-organized and cohesive. James improves his chances of completing a research paper that satisfies all standards by taking the time to learn how to start a research paper and adhere to the proper writing procedure.

Decide on a Research Paper Topic

The selection of a research paper topic is a pivotal decision that shapes every aspect of your writing journey. From the beginning to the end, the chosen subject sets the tone for your entire paper. Therefore, your foremost priority should be dedicated to the thoughtful and strategic process of selecting the most fitting research paper topic. It is crucial to choose a subject that provides a wealth of information and complexity so that a thorough and insightful discussion may take place.

Furthermore, it's crucial to make your research topic feel personal and interesting. Instead of picking a topic just because it meets the requirements, choose something that genuinely catches your interest. The best research paper topic is one that has enough material for study and keeps you excited and motivated as you go through the writing and research journey.

Gather Early Information

Start your research early. A research paper involves deep analysis and investigation. Checking previous studies about your topic helps you create a strong thesis statement and refine your chosen subject. Early research does two things: it clears up any confusion you might have and shows you the best ways to find more important information. It's like laying the groundwork for your study.

Make a Strong Thesis Statement 

Write a thesis statement on the basis of your research. The thesis statement defines the purpose and stance of the paper. It is an explanation of your primary argument. Your research question should be addressed in the thesis statement. It should also include a synopsis of the arguments and evidence you plan to use in support of your position.

A clear, controversial, and cohesive thesis statement is ideal. This means that it should have a brief overview of your argument in a few phrases. It must have a claim that needs more support or analysis and a cohesive point that ties into each area of the work. Throughout the writing process, the thesis statement serves as a roadmap. However, it is likely to be refined as you conduct extra research. This main point must be developed and supported in every paragraph.

Develop an Outline 

A research paper's outline consists of a synopsis of the key ideas, evidence, and any other information you would like to add. It is organized into sections with headings so that, before you begin writing, you know roughly how the document will look. It is worthwhile to invest some time in creating a structured plan. Moreover, it can greatly improve the efficiency of the writing process.

Tip: You can use ChatGPT to create an outline for your research paper. This way, you can organize and structure your paper well. 

Write the first draft of research paper 

After completing the outline, it's time to add data in the outline. This process takes a lot of effort and attention, but it can go more smoothly if you prepare ahead and organize yourself well. It's normal to feel overwhelmed when writing the introduction of a research paper . To meet this challenge, think about grabbing the reader's interest right away using an attention-grabbing opening statement or tale. Next, provide a succinct and captivating thesis statement that sums up your paper's primary point of contention. Expand on your thesis by giving pertinent background data and putting the importance of your study issue in context. The in-depth information and proof should be saved for the later portions of your work. In the main part of your research paper, you share what you found and analyzed in your study. To make it clear and organized, think about dividing it into parts or sections with subheadings. Each part should talk about a different aspect related to your main idea. Use examples, evidence, and explanations in each part to support what you're saying. Remember, this is just the first version, so focus on getting your ideas out there rather than trying to make everything perfect. Maintaining a coherent flow throughout your paper depends on the seamless connections between your paragraphs. Every paragraph should start with a topic phrase that connects the topics in the previous and next paragraphs. Make use of transitional words and phrases to seamlessly move your reader from one idea to the next.  Once you've written the main part of your paper, it's time to make a strong conclusion. Sum up your main points and conclusions briefly, emphasizing why they matter. Aim to leave the reader with a new thought or perspective, not just repeating what you've already said. Avoid introducing new information in the conclusion; focus on repeating the important ideas and giving the reader a sense of completion.

Use Proper Citations      

Have you reviewed the research paper guidelines before starting it? It is very important to cite your resources properly because it sets your paper apart from others. Each time you use any information in your paper, make a note of the source where that information came from. 

Due to its significance, citations should follow precise formatting rules. But the problem here is that there are different types of formatting styles, such as MLA, APA, Chicago, and Turabian. If you’re asked to format your paper in APA format, you can check our latest guide on how to write a research paper in APA format .  At first, citing sources might seem tricky with all the rules and details. But once you understand them, citing your sources will become easy.

Tip: You can use online citation generators, such as Citation Machine , MyBib , etc., to create your research paper citation.

Revise and Polish Your Paper

The most important factor in learning how to write a research paper is to dedicate time to proofreading and editing your paper. For thorough review, we advise conducting two editing sessions. One session will focus on addressing the structural issues, and the other is dedicated to improving spelling, grammar, and word choice. When you're doing the structural edit, use this checklist:

• Is your main point clear in the thesis statement?
• Does your paper have a smooth flow from start to finish?
• Are your ideas organized well in each paragraph?
• Did you back up your arguments with specific details and facts?
• Do your arguments really support your main point?
• Have you removed any unnecessary repetition to make things clear and brief?
• Did you cite your sources correctly to give credit and avoid plagiarism?

To make sure that your citations are precise and formatted correctly, you can also review the instructions on how to write an essay in MLA format . Once structural issues have been resolved, shift your attention to the editing of word choice, grammar, and spelling. Think about the following elements:

• Check if your writing is clear and straightforward.
• Make sure your sentences connect well and express your ideas effectively.
• Remove unnecessary words that might weaken your writing.
• Double-check for grammar, spelling, and punctuation.
• Reading your paper out loud or having someone else review it can help catch any overlooked issues.
• Editing is a different skill than writing, and proficiency in one doesn't imply mastering the other.

Fixing technical issues, such as grammar and spelling, is easy with a spellchecker in your word processor or, even better, a writing assistant like Grammarly. It not only corrects mistakes but also offers suggestions for better word choices and tone. 

Tools and Resources

If you don't know how to write a research paper and are looking for online tools and resources, this section is for you.

Google Scholar

This is the official Google search engine, and it is only meant to be used for academic articles. It's a fantastic way to find recent research and sources. It is also free to use.

Zotero 

Zotero is a free of charge, open-source research manager that functions as an interface between an organizational CMS and an academic research search engine. You can use it to search the internet for research materials related to your subject and quickly share them with peers. It also creates citations on its own.

Google Charts

With the help of this useful and free tool from Google, you can make simple graphs and charts using any data you provide. If you need to discuss complex evidential study, charts, and graphs are a great visual assistance for presenting numerical data. 

How long should a research paper be?

The size of the paper depends on multiple factors, such as the topic and the instructions given by the college or university. Always prioritize substance and quality over quantity. Research papers for undergraduate assignments usually have a page count of five to fifteen, though this can change depending on the course and the professor's expectations. On the other hand, Graduate-level research papers that are meant for publication in scholarly journals can often be much longer—20, 30, or even 50 pages.

Best Tips for Writing a Research Paper

While writing a research paper, keep the following points in mind:

• Pick a topic that fascinates you when performing research. When you are passionate about a topic, writing a paper becomes more engaging.
• Select a thesis statement that accurately expresses your true opinion or hypothesis. Let your thesis guide your writing.
• Keep in mind all grammatical rules. This facilitates the editing process.
• Sentences should be complete without being overly wordy.
• Ensure that each paragraph contains a minimum of four sentences.
• Reference every source you use. You should never pass off someone else's study as your own. Ensure that the original author receives credit for his or her work.

Here are some research tips:

• Make use of reliable sources. Websites that are editable by the public may include incorrect information.
• Verify if the data is accurate. Check the dates to find out when the study was finished. It might be better to look for something more recent if it was more than 20 years ago.
• Make a list of all the information you have about the resource. You might find this useful when creating your list of references.
• If a resource was used throughout the work, include it in your reference list.

Frequently Asked Questions

The perception and appreciation of food flavor depends on many interacting chemical compounds and external factors, and therefore proves challenging to understand and predict. Here, we combine extensive chemical and sensory analyses of 250 different beers to train machine learning models that allow predicting flavor and consumer appreciation. For each beer, we measure over 200 chemical properties, perform quantitative descriptive sensory analysis with a trained tasting panel and map data from over 180,000 consumer reviews to train 10 different machine learning models. The best-performing algorithm, Gradient Boosting, yields models that significantly outperform predictions based on conventional statistics and accurately predict complex food features and consumer appreciation from chemical profiles. Model dissection allows identifying specific and unexpected compounds as drivers of beer flavor and appreciation. Adding these compounds results in variants of commercial alcoholic and non-alcoholic beers with improved consumer appreciation. Together, our study reveals how big data and machine learning uncover complex links between food chemistry, flavor and consumer perception, and lays the foundation to develop novel, tailored foods with superior flavors.

Introduction

Predicting and understanding food perception and appreciation is one of the major challenges in food science. Accurate modeling of food flavor and appreciation could yield important opportunities for both producers and consumers, including quality control, product fingerprinting, counterfeit detection, spoilage detection, and the development of new products and product combinations (food pairing) 1 , 2 , 3 , 4 , 5 , 6 . Accurate models for flavor and consumer appreciation would contribute greatly to our scientific understanding of how humans perceive and appreciate flavor. Moreover, accurate predictive models would also facilitate and standardize existing food assessment methods and could supplement or replace assessments by trained and consumer tasting panels, which are variable, expensive and time-consuming 7 , 8 , 9 . Lastly, apart from providing objective, quantitative, accurate and contextual information that can help producers, models can also guide consumers in understanding their personal preferences 10 .

Despite the myriad of applications, predicting food flavor and appreciation from its chemical properties remains a largely elusive goal in sensory science, especially for complex food and beverages 11 , 12 . A key obstacle is the immense number of flavor-active chemicals underlying food flavor. Flavor compounds can vary widely in chemical structure and concentration, making them technically challenging and labor-intensive to quantify, even in the face of innovations in metabolomics, such as non-targeted metabolic fingerprinting 13 , 14 . Moreover, sensory analysis is perhaps even more complicated. Flavor perception is highly complex, resulting from hundreds of different molecules interacting at the physiochemical and sensorial level. Sensory perception is often non-linear, characterized by complex and concentration-dependent synergistic and antagonistic effects 15 , 16 , 17 , 18 , 19 , 20 , 21 that are further convoluted by the genetics, environment, culture and psychology of consumers 22 , 23 , 24 . Perceived flavor is therefore difficult to measure, with problems of sensitivity, accuracy, and reproducibility that can only be resolved by gathering sufficiently large datasets 25 . Trained tasting panels are considered the prime source of quality sensory data, but require meticulous training, are low throughput and high cost. Public databases containing consumer reviews of food products could provide a valuable alternative, especially for studying appreciation scores, which do not require formal training 25 . Public databases offer the advantage of amassing large amounts of data, increasing the statistical power to identify potential drivers of appreciation. However, public datasets suffer from biases, including a bias in the volunteers that contribute to the database, as well as confounding factors such as price, cult status and psychological conformity towards previous ratings of the product.

Classical multivariate statistics and machine learning methods have been used to predict flavor of specific compounds by, for example, linking structural properties of a compound to its potential biological activities or linking concentrations of specific compounds to sensory profiles 1 , 26 . Importantly, most previous studies focused on predicting organoleptic properties of single compounds (often based on their chemical structure) 27 , 28 , 29 , 30 , 31 , 32 , 33 , thus ignoring the fact that these compounds are present in a complex matrix in food or beverages and excluding complex interactions between compounds. Moreover, the classical statistics commonly used in sensory science 34 , 35 , 36 , 37 , 38 , 39 require a large sample size and sufficient variance amongst predictors to create accurate models. They are not fit for studying an extensive set of hundreds of interacting flavor compounds, since they are sensitive to outliers, have a high tendency to overfit and are less suited for non-linear and discontinuous relationships 40 .

In this study, we combine extensive chemical analyses and sensory data of a set of different commercial beers with machine learning approaches to develop models that predict taste, smell, mouthfeel and appreciation from compound concentrations. Beer is particularly suited to model the relationship between chemistry, flavor and appreciation. First, beer is a complex product, consisting of thousands of flavor compounds that partake in complex sensory interactions 41 , 42 , 43 . This chemical diversity arises from the raw materials (malt, yeast, hops, water and spices) and biochemical conversions during the brewing process (kilning, mashing, boiling, fermentation, maturation and aging) 44 , 45 . Second, the advent of the internet saw beer consumers embrace online review platforms, such as RateBeer (ZX Ventures, Anheuser-Busch InBev SA/NV) and BeerAdvocate (Next Glass, inc.). In this way, the beer community provides massive data sets of beer flavor and appreciation scores, creating extraordinarily large sensory databases to complement the analyses of our professional sensory panel. Specifically, we characterize over 200 chemical properties of 250 commercial beers, spread across 22 beer styles, and link these to the descriptive sensory profiling data of a 16-person in-house trained tasting panel and data acquired from over 180,000 public consumer reviews. These unique and extensive datasets enable us to train a suite of machine learning models to predict flavor and appreciation from a beer’s chemical profile. Dissection of the best-performing models allows us to pinpoint specific compounds as potential drivers of beer flavor and appreciation. Follow-up experiments confirm the importance of these compounds and ultimately allow us to significantly improve the flavor and appreciation of selected commercial beers. Together, our study represents a significant step towards understanding complex flavors and reinforces the value of machine learning to develop and refine complex foods. In this way, it represents a stepping stone for further computer-aided food engineering applications 46 .

To generate a comprehensive dataset on beer flavor, we selected 250 commercial Belgian beers across 22 different beer styles (Supplementary Fig.  S1 ). Beers with ≤ 4.2% alcohol by volume (ABV) were classified as non-alcoholic and low-alcoholic. Blonds and Tripels constitute a significant portion of the dataset (12.4% and 11.2%, respectively) reflecting their presence on the Belgian beer market and the heterogeneity of beers within these styles. By contrast, lager beers are less diverse and dominated by a handful of brands. Rare styles such as Brut or Faro make up only a small fraction of the dataset (2% and 1%, respectively) because fewer of these beers are produced and because they are dominated by distinct characteristics in terms of flavor and chemical composition.

Extensive analysis identifies relationships between chemical compounds in beer

For each beer, we measured 226 different chemical properties, including common brewing parameters such as alcohol content, iso-alpha acids, pH, sugar concentration 47 , and over 200 flavor compounds (Methods, Supplementary Table  S1 ). A large portion (37.2%) are terpenoids arising from hopping, responsible for herbal and fruity flavors 16 , 48 . A second major category are yeast metabolites, such as esters and alcohols, that result in fruity and solvent notes 48 , 49 , 50 . Other measured compounds are primarily derived from malt, or other microbes such as non- Saccharomyces yeasts and bacteria (‘wild flora’). Compounds that arise from spices or staling are labeled under ‘Others’. Five attributes (caloric value, total acids and total ester, hop aroma and sulfur compounds) are calculated from multiple individually measured compounds.

As a first step in identifying relationships between chemical properties, we determined correlations between the concentrations of the compounds (Fig.  1 , upper panel, Supplementary Data  1 and 2 , and Supplementary Fig.  S2 . For the sake of clarity, only a subset of the measured compounds is shown in Fig.  1 ). Compounds of the same origin typically show a positive correlation, while absence of correlation hints at parameters varying independently. For example, the hop aroma compounds citronellol, and alpha-terpineol show moderate correlations with each other (Spearman’s rho=0.39 and 0.57), but not with the bittering hop component iso-alpha acids (Spearman’s rho=0.16 and −0.07). This illustrates how brewers can independently modify hop aroma and bitterness by selecting hop varieties and dosage time. If hops are added early in the boiling phase, chemical conversions increase bitterness while aromas evaporate, conversely, late addition of hops preserves aroma but limits bitterness 51 . Similarly, hop-derived iso-alpha acids show a strong anti-correlation with lactic acid and acetic acid, likely reflecting growth inhibition of lactic acid and acetic acid bacteria, or the consequent use of fewer hops in sour beer styles, such as West Flanders ales and Fruit beers, that rely on these bacteria for their distinct flavors 52 . Finally, yeast-derived esters (ethyl acetate, ethyl decanoate, ethyl hexanoate, ethyl octanoate) and alcohols (ethanol, isoamyl alcohol, isobutanol, and glycerol), correlate with Spearman coefficients above 0.5, suggesting that these secondary metabolites are correlated with the yeast genetic background and/or fermentation parameters and may be difficult to influence individually, although the choice of yeast strain may offer some control 53 .

Spearman rank correlations are shown. Descriptors are grouped according to their origin (malt (blue), hops (green), yeast (red), wild flora (yellow), Others (black)), and sensory aspect (aroma, taste, palate, and overall appreciation). Please note that for the chemical compounds, for the sake of clarity, only a subset of the total number of measured compounds is shown, with an emphasis on the key compounds for each source. For more details, see the main text and Methods section. Chemical data can be found in Supplementary Data  1 , correlations between all chemical compounds are depicted in Supplementary Fig.  S2 and correlation values can be found in Supplementary Data  2 . See Supplementary Data  4 for sensory panel assessments and Supplementary Data  5 for correlation values between all sensory descriptors.

Interestingly, different beer styles show distinct patterns for some flavor compounds (Supplementary Fig.  S3 ). These observations agree with expectations for key beer styles, and serve as a control for our measurements. For instance, Stouts generally show high values for color (darker), while hoppy beers contain elevated levels of iso-alpha acids, compounds associated with bitter hop taste. Acetic and lactic acid are not prevalent in most beers, with notable exceptions such as Kriek, Lambic, Faro, West Flanders ales and Flanders Old Brown, which use acid-producing bacteria ( Lactobacillus and Pediococcus ) or unconventional yeast ( Brettanomyces ) 54 , 55 . Glycerol, ethanol and esters show similar distributions across all beer styles, reflecting their common origin as products of yeast metabolism during fermentation 45 , 53 . Finally, low/no-alcohol beers contain low concentrations of glycerol and esters. This is in line with the production process for most of the low/no-alcohol beers in our dataset, which are produced through limiting fermentation or by stripping away alcohol via evaporation or dialysis, with both methods having the unintended side-effect of reducing the amount of flavor compounds in the final beer 56 , 57 .

Besides expected associations, our data also reveals less trivial associations between beer styles and specific parameters. For example, geraniol and citronellol, two monoterpenoids responsible for citrus, floral and rose flavors and characteristic of Citra hops, are found in relatively high amounts in Christmas, Saison, and Brett/co-fermented beers, where they may originate from terpenoid-rich spices such as coriander seeds instead of hops 58 .

Tasting panel assessments reveal sensorial relationships in beer

To assess the sensory profile of each beer, a trained tasting panel evaluated each of the 250 beers for 50 sensory attributes, including different hop, malt and yeast flavors, off-flavors and spices. Panelists used a tasting sheet (Supplementary Data  3 ) to score the different attributes. Panel consistency was evaluated by repeating 12 samples across different sessions and performing ANOVA. In 95% of cases no significant difference was found across sessions ( p  > 0.05), indicating good panel consistency (Supplementary Table  S2 ).

Aroma and taste perception reported by the trained panel are often linked (Fig.  1 , bottom left panel and Supplementary Data  4 and 5 ), with high correlations between hops aroma and taste (Spearman’s rho=0.83). Bitter taste was found to correlate with hop aroma and taste in general (Spearman’s rho=0.80 and 0.69), and particularly with “grassy” noble hops (Spearman’s rho=0.75). Barnyard flavor, most often associated with sour beers, is identified together with stale hops (Spearman’s rho=0.97) that are used in these beers. Lactic and acetic acid, which often co-occur, are correlated (Spearman’s rho=0.66). Interestingly, sweetness and bitterness are anti-correlated (Spearman’s rho = −0.48), confirming the hypothesis that they mask each other 59 , 60 . Beer body is highly correlated with alcohol (Spearman’s rho = 0.79), and overall appreciation is found to correlate with multiple aspects that describe beer mouthfeel (alcohol, carbonation; Spearman’s rho= 0.32, 0.39), as well as with hop and ester aroma intensity (Spearman’s rho=0.39 and 0.35).

Similar to the chemical analyses, sensorial analyses confirmed typical features of specific beer styles (Supplementary Fig.  S4 ). For example, sour beers (Faro, Flanders Old Brown, Fruit beer, Kriek, Lambic, West Flanders ale) were rated acidic, with flavors of both acetic and lactic acid. Hoppy beers were found to be bitter and showed hop-associated aromas like citrus and tropical fruit. Malt taste is most detected among scotch, stout/porters, and strong ales, while low/no-alcohol beers, which often have a reputation for being ‘worty’ (reminiscent of unfermented, sweet malt extract) appear in the middle. Unsurprisingly, hop aromas are most strongly detected among hoppy beers. Like its chemical counterpart (Supplementary Fig.  S3 ), acidity shows a right-skewed distribution, with the most acidic beers being Krieks, Lambics, and West Flanders ales.

Tasting panel assessments of specific flavors correlate with chemical composition

We find that the concentrations of several chemical compounds strongly correlate with specific aroma or taste, as evaluated by the tasting panel (Fig.  2 , Supplementary Fig.  S5 , Supplementary Data  6 ). In some cases, these correlations confirm expectations and serve as a useful control for data quality. For example, iso-alpha acids, the bittering compounds in hops, strongly correlate with bitterness (Spearman’s rho=0.68), while ethanol and glycerol correlate with tasters’ perceptions of alcohol and body, the mouthfeel sensation of fullness (Spearman’s rho=0.82/0.62 and 0.72/0.57 respectively) and darker color from roasted malts is a good indication of malt perception (Spearman’s rho=0.54).

Heatmap colors indicate Spearman’s Rho. Axes are organized according to sensory categories (aroma, taste, mouthfeel, overall), chemical categories and chemical sources in beer (malt (blue), hops (green), yeast (red), wild flora (yellow), Others (black)). See Supplementary Data  6 for all correlation values.

Interestingly, for some relationships between chemical compounds and perceived flavor, correlations are weaker than expected. For example, the rose-smelling phenethyl acetate only weakly correlates with floral aroma. This hints at more complex relationships and interactions between compounds and suggests a need for a more complex model than simple correlations. Lastly, we uncovered unexpected correlations. For instance, the esters ethyl decanoate and ethyl octanoate appear to correlate slightly with hop perception and bitterness, possibly due to their fruity flavor. Iron is anti-correlated with hop aromas and bitterness, most likely because it is also anti-correlated with iso-alpha acids. This could be a sign of metal chelation of hop acids 61 , given that our analyses measure unbound hop acids and total iron content, or could result from the higher iron content in dark and Fruit beers, which typically have less hoppy and bitter flavors 62 .

Public consumer reviews complement expert panel data

To complement and expand the sensory data of our trained tasting panel, we collected 180,000 reviews of our 250 beers from the online consumer review platform RateBeer. This provided numerical scores for beer appearance, aroma, taste, palate, overall quality as well as the average overall score.

Public datasets are known to suffer from biases, such as price, cult status and psychological conformity towards previous ratings of a product. For example, prices correlate with appreciation scores for these online consumer reviews (rho=0.49, Supplementary Fig.  S6 ), but not for our trained tasting panel (rho=0.19). This suggests that prices affect consumer appreciation, which has been reported in wine 63 , while blind tastings are unaffected. Moreover, we observe that some beer styles, like lagers and non-alcoholic beers, generally receive lower scores, reflecting that online reviewers are mostly beer aficionados with a preference for specialty beers over lager beers. In general, we find a modest correlation between our trained panel’s overall appreciation score and the online consumer appreciation scores (Fig.  3 , rho=0.29). Apart from the aforementioned biases in the online datasets, serving temperature, sample freshness and surroundings, which are all tightly controlled during the tasting panel sessions, can vary tremendously across online consumers and can further contribute to (among others, appreciation) differences between the two categories of tasters. Importantly, in contrast to the overall appreciation scores, for many sensory aspects the results from the professional panel correlated well with results obtained from RateBeer reviews. Correlations were highest for features that are relatively easy to recognize even for untrained tasters, like bitterness, sweetness, alcohol and malt aroma (Fig.  3 and below).

RateBeer text mining results can be found in Supplementary Data  7 . Rho values shown are Spearman correlation values, with asterisks indicating significant correlations ( p  < 0.05, two-sided). All p values were smaller than 0.001, except for Esters aroma (0.0553), Esters taste (0.3275), Esters aroma—banana (0.0019), Coriander (0.0508) and Diacetyl (0.0134).

Besides collecting consumer appreciation from these online reviews, we developed automated text analysis tools to gather additional data from review texts (Supplementary Data  7 ). Processing review texts on the RateBeer database yielded comparable results to the scores given by the trained panel for many common sensory aspects, including acidity, bitterness, sweetness, alcohol, malt, and hop tastes (Fig.  3 ). This is in line with what would be expected, since these attributes require less training for accurate assessment and are less influenced by environmental factors such as temperature, serving glass and odors in the environment. Consumer reviews also correlate well with our trained panel for 4-vinyl guaiacol, a compound associated with a very characteristic aroma. By contrast, correlations for more specific aromas like ester, coriander or diacetyl are underrepresented in the online reviews, underscoring the importance of using a trained tasting panel and standardized tasting sheets with explicit factors to be scored for evaluating specific aspects of a beer. Taken together, our results suggest that public reviews are trustworthy for some, but not all, flavor features and can complement or substitute taste panel data for these sensory aspects.

Models can predict beer sensory profiles from chemical data

The rich datasets of chemical analyses, tasting panel assessments and public reviews gathered in the first part of this study provided us with a unique opportunity to develop predictive models that link chemical data to sensorial features. Given the complexity of beer flavor, basic statistical tools such as correlations or linear regression may not always be the most suitable for making accurate predictions. Instead, we applied different machine learning models that can model both simple linear and complex interactive relationships. Specifically, we constructed a set of regression models to predict (a) trained panel scores for beer flavor and quality and (b) public reviews’ appreciation scores from beer chemical profiles. We trained and tested 10 different models (Methods), 3 linear regression-based models (simple linear regression with first-order interactions (LR), lasso regression with first-order interactions (Lasso), partial least squares regressor (PLSR)), 5 decision tree models (AdaBoost regressor (ABR), extra trees (ET), gradient boosting regressor (GBR), random forest (RF) and XGBoost regressor (XGBR)), 1 support vector regression (SVR), and 1 artificial neural network (ANN) model.

To compare the performance of our machine learning models, the dataset was randomly split into a training and test set, stratified by beer style. After a model was trained on data in the training set, its performance was evaluated on its ability to predict the test dataset obtained from multi-output models (based on the coefficient of determination, see Methods). Additionally, individual-attribute models were ranked per descriptor and the average rank was calculated, as proposed by Korneva et al. 64 . Importantly, both ways of evaluating the models’ performance agreed in general. Performance of the different models varied (Table  1 ). It should be noted that all models perform better at predicting RateBeer results than results from our trained tasting panel. One reason could be that sensory data is inherently variable, and this variability is averaged out with the large number of public reviews from RateBeer. Additionally, all tree-based models perform better at predicting taste than aroma. Linear models (LR) performed particularly poorly, with negative R 2 values, due to severe overfitting (training set R 2  = 1). Overfitting is a common issue in linear models with many parameters and limited samples, especially with interaction terms further amplifying the number of parameters. L1 regularization (Lasso) successfully overcomes this overfitting, out-competing multiple tree-based models on the RateBeer dataset. Similarly, the dimensionality reduction of PLSR avoids overfitting and improves performance, to some extent. Still, tree-based models (ABR, ET, GBR, RF and XGBR) show the best performance, out-competing the linear models (LR, Lasso, PLSR) commonly used in sensory science 65 .

GBR models showed the best overall performance in predicting sensory responses from chemical information, with R 2 values up to 0.75 depending on the predicted sensory feature (Supplementary Table  S4 ). The GBR models predict consumer appreciation (RateBeer) better than our trained panel’s appreciation (R 2 value of 0.67 compared to R 2 value of 0.09) (Supplementary Table  S3 and Supplementary Table  S4 ). ANN models showed intermediate performance, likely because neural networks typically perform best with larger datasets 66 . The SVR shows intermediate performance, mostly due to the weak predictions of specific attributes that lower the overall performance (Supplementary Table  S4 ).

Model dissection identifies specific, unexpected compounds as drivers of consumer appreciation

Next, we leveraged our models to infer important contributors to sensory perception and consumer appreciation. Consumer preference is a crucial sensory aspects, because a product that shows low consumer appreciation scores often does not succeed commercially 25 . Additionally, the requirement for a large number of representative evaluators makes consumer trials one of the more costly and time-consuming aspects of product development. Hence, a model for predicting chemical drivers of overall appreciation would be a welcome addition to the available toolbox for food development and optimization.

Since GBR models on our RateBeer dataset showed the best overall performance, we focused on these models. Specifically, we used two approaches to identify important contributors. First, rankings of the most important predictors for each sensorial trait in the GBR models were obtained based on impurity-based feature importance (mean decrease in impurity). High-ranked parameters were hypothesized to be either the true causal chemical properties underlying the trait, to correlate with the actual causal properties, or to take part in sensory interactions affecting the trait 67 (Fig.  4A ). In a second approach, we used SHAP 68 to determine which parameters contributed most to the model for making predictions of consumer appreciation (Fig.  4B ). SHAP calculates parameter contributions to model predictions on a per-sample basis, which can be aggregated into an importance score.

A The impurity-based feature importance (mean deviance in impurity, MDI) calculated from the Gradient Boosting Regression (GBR) model predicting RateBeer appreciation scores. The top 15 highest ranked chemical properties are shown. B SHAP summary plot for the top 15 parameters contributing to our GBR model. Each point on the graph represents a sample from our dataset. The color represents the concentration of that parameter, with bluer colors representing low values and redder colors representing higher values. Greater absolute values on the horizontal axis indicate a higher impact of the parameter on the prediction of the model. C Spearman correlations between the 15 most important chemical properties and consumer overall appreciation. Numbers indicate the Spearman Rho correlation coefficient, and the rank of this correlation compared to all other correlations. The top 15 important compounds were determined using SHAP (panel B).

Both approaches identified ethyl acetate as the most predictive parameter for beer appreciation (Fig.  4 ). Ethyl acetate is the most abundant ester in beer with a typical ‘fruity’, ‘solvent’ and ‘alcoholic’ flavor, but is often considered less important than other esters like isoamyl acetate. The second most important parameter identified by SHAP is ethanol, the most abundant beer compound after water. Apart from directly contributing to beer flavor and mouthfeel, ethanol drastically influences the physical properties of beer, dictating how easily volatile compounds escape the beer matrix to contribute to beer aroma 69 . Importantly, it should also be noted that the importance of ethanol for appreciation is likely inflated by the very low appreciation scores of non-alcoholic beers (Supplementary Fig.  S4 ). Despite not often being considered a driver of beer appreciation, protein level also ranks highly in both approaches, possibly due to its effect on mouthfeel and body 70 . Lactic acid, which contributes to the tart taste of sour beers, is the fourth most important parameter identified by SHAP, possibly due to the generally high appreciation of sour beers in our dataset.

Interestingly, some of the most important predictive parameters for our model are not well-established as beer flavors or are even commonly regarded as being negative for beer quality. For example, our models identify methanethiol and ethyl phenyl acetate, an ester commonly linked to beer staling 71 , as a key factor contributing to beer appreciation. Although there is no doubt that high concentrations of these compounds are considered unpleasant, the positive effects of modest concentrations are not yet known 72 , 73 .

To compare our approach to conventional statistics, we evaluated how well the 15 most important SHAP-derived parameters correlate with consumer appreciation (Fig.  4C ). Interestingly, only 6 of the properties derived by SHAP rank amongst the top 15 most correlated parameters. For some chemical compounds, the correlations are so low that they would have likely been considered unimportant. For example, lactic acid, the fourth most important parameter, shows a bimodal distribution for appreciation, with sour beers forming a separate cluster, that is missed entirely by the Spearman correlation. Additionally, the correlation plots reveal outliers, emphasizing the need for robust analysis tools. Together, this highlights the need for alternative models, like the Gradient Boosting model, that better grasp the complexity of (beer) flavor.

Finally, to observe the relationships between these chemical properties and their predicted targets, partial dependence plots were constructed for the six most important predictors of consumer appreciation 74 , 75 , 76 (Supplementary Fig.  S7 ). One-way partial dependence plots show how a change in concentration affects the predicted appreciation. These plots reveal an important limitation of our models: appreciation predictions remain constant at ever-increasing concentrations. This implies that once a threshold concentration is reached, further increasing the concentration does not affect appreciation. This is false, as it is well-documented that certain compounds become unpleasant at high concentrations, including ethyl acetate (‘nail polish’) 77 and methanethiol (‘sulfury’ and ‘rotten cabbage’) 78 . The inability of our models to grasp that flavor compounds have optimal levels, above which they become negative, is a consequence of working with commercial beer brands where (off-)flavors are rarely too high to negatively impact the product. The two-way partial dependence plots show how changing the concentration of two compounds influences predicted appreciation, visualizing their interactions (Supplementary Fig.  S7 ). In our case, the top 5 parameters are dominated by additive or synergistic interactions, with high concentrations for both compounds resulting in the highest predicted appreciation.

To assess the robustness of our best-performing models and model predictions, we performed 100 iterations of the GBR, RF and ET models. In general, all iterations of the models yielded similar performance (Supplementary Fig.  S8 ). Moreover, the main predictors (including the top predictors ethanol and ethyl acetate) remained virtually the same, especially for GBR and RF. For the iterations of the ET model, we did observe more variation in the top predictors, which is likely a consequence of the model’s inherent random architecture in combination with co-correlations between certain predictors. However, even in this case, several of the top predictors (ethanol and ethyl acetate) remain unchanged, although their rank in importance changes (Supplementary Fig.  S8 ).

Next, we investigated if a combination of RateBeer and trained panel data into one consolidated dataset would lead to stronger models, under the hypothesis that such a model would suffer less from bias in the datasets. A GBR model was trained to predict appreciation on the combined dataset. This model underperformed compared to the RateBeer model, both in the native case and when including a dataset identifier (R 2  = 0.67, 0.26 and 0.42 respectively). For the latter, the dataset identifier is the most important feature (Supplementary Fig.  S9 ), while most of the feature importance remains unchanged, with ethyl acetate and ethanol ranking highest, like in the original model trained only on RateBeer data. It seems that the large variation in the panel dataset introduces noise, weakening the models’ performances and reliability. In addition, it seems reasonable to assume that both datasets are fundamentally different, with the panel dataset obtained by blind tastings by a trained professional panel.

Lastly, we evaluated whether beer style identifiers would further enhance the model’s performance. A GBR model was trained with parameters that explicitly encoded the styles of the samples. This did not improve model performance (R2 = 0.66 with style information vs R2 = 0.67). The most important chemical features are consistent with the model trained without style information (eg. ethanol and ethyl acetate), and with the exception of the most preferred (strong ale) and least preferred (low/no-alcohol) styles, none of the styles were among the most important features (Supplementary Fig.  S9 , Supplementary Table  S5 and S6 ). This is likely due to a combination of style-specific chemical signatures, such as iso-alpha acids and lactic acid, that implicitly convey style information to the original models, as well as the low number of samples belonging to some styles, making it difficult for the model to learn style-specific patterns. Moreover, beer styles are not rigorously defined, with some styles overlapping in features and some beers being misattributed to a specific style, all of which leads to more noise in models that use style parameters.

Model validation

To test if our predictive models give insight into beer appreciation, we set up experiments aimed at improving existing commercial beers. We specifically selected overall appreciation as the trait to be examined because of its complexity and commercial relevance. Beer flavor comprises a complex bouquet rather than single aromas and tastes 53 . Hence, adding a single compound to the extent that a difference is noticeable may lead to an unbalanced, artificial flavor. Therefore, we evaluated the effect of combinations of compounds. Because Blond beers represent the most extensive style in our dataset, we selected a beer from this style as the starting material for these experiments (Beer 64 in Supplementary Data  1 ).

In the first set of experiments, we adjusted the concentrations of compounds that made up the most important predictors of overall appreciation (ethyl acetate, ethanol, lactic acid, ethyl phenyl acetate) together with correlated compounds (ethyl hexanoate, isoamyl acetate, glycerol), bringing them up to 95 th percentile ethanol-normalized concentrations (Methods) within the Blond group (‘Spiked’ concentration in Fig.  5A ). Compared to controls, the spiked beers were found to have significantly improved overall appreciation among trained panelists, with panelist noting increased intensity of ester flavors, sweetness, alcohol, and body fullness (Fig.  5B ). To disentangle the contribution of ethanol to these results, a second experiment was performed without the addition of ethanol. This resulted in a similar outcome, including increased perception of alcohol and overall appreciation.

Adding the top chemical compounds, identified as best predictors of appreciation by our model, into poorly appreciated beers results in increased appreciation from our trained panel. Results of sensory tests between base beers and those spiked with compounds identified as the best predictors by the model. A Blond and Non/Low-alcohol (0.0% ABV) base beers were brought up to 95th-percentile ethanol-normalized concentrations within each style. B For each sensory attribute, tasters indicated the more intense sample and selected the sample they preferred. The numbers above the bars correspond to the p values that indicate significant changes in perceived flavor (two-sided binomial test: alpha 0.05, n  = 20 or 13).

In a last experiment, we tested whether using the model’s predictions can boost the appreciation of a non-alcoholic beer (beer 223 in Supplementary Data  1 ). Again, the addition of a mixture of predicted compounds (omitting ethanol, in this case) resulted in a significant increase in appreciation, body, ester flavor and sweetness.

Predicting flavor and consumer appreciation from chemical composition is one of the ultimate goals of sensory science. A reliable, systematic and unbiased way to link chemical profiles to flavor and food appreciation would be a significant asset to the food and beverage industry. Such tools would substantially aid in quality control and recipe development, offer an efficient and cost-effective alternative to pilot studies and consumer trials and would ultimately allow food manufacturers to produce superior, tailor-made products that better meet the demands of specific consumer groups more efficiently.

A limited set of studies have previously tried, to varying degrees of success, to predict beer flavor and beer popularity based on (a limited set of) chemical compounds and flavors 79 , 80 . Current sensitive, high-throughput technologies allow measuring an unprecedented number of chemical compounds and properties in a large set of samples, yielding a dataset that can train models that help close the gaps between chemistry and flavor, even for a complex natural product like beer. To our knowledge, no previous research gathered data at this scale (250 samples, 226 chemical parameters, 50 sensory attributes and 5 consumer scores) to disentangle and validate the chemical aspects driving beer preference using various machine-learning techniques. We find that modern machine learning models outperform conventional statistical tools, such as correlations and linear models, and can successfully predict flavor appreciation from chemical composition. This could be attributed to the natural incorporation of interactions and non-linear or discontinuous effects in machine learning models, which are not easily grasped by the linear model architecture. While linear models and partial least squares regression represent the most widespread statistical approaches in sensory science, in part because they allow interpretation 65 , 81 , 82 , modern machine learning methods allow for building better predictive models while preserving the possibility to dissect and exploit the underlying patterns. Of the 10 different models we trained, tree-based models, such as our best performing GBR, showed the best overall performance in predicting sensory responses from chemical information, outcompeting artificial neural networks. This agrees with previous reports for models trained on tabular data 83 . Our results are in line with the findings of Colantonio et al. who also identified the gradient boosting architecture as performing best at predicting appreciation and flavor (of tomatoes and blueberries, in their specific study) 26 . Importantly, besides our larger experimental scale, we were able to directly confirm our models’ predictions in vivo.

Our study confirms that flavor compound concentration does not always correlate with perception, suggesting complex interactions that are often missed by more conventional statistics and simple models. Specifically, we find that tree-based algorithms may perform best in developing models that link complex food chemistry with aroma. Furthermore, we show that massive datasets of untrained consumer reviews provide a valuable source of data, that can complement or even replace trained tasting panels, especially for appreciation and basic flavors, such as sweetness and bitterness. This holds despite biases that are known to occur in such datasets, such as price or conformity bias. Moreover, GBR models predict taste better than aroma. This is likely because taste (e.g. bitterness) often directly relates to the corresponding chemical measurements (e.g., iso-alpha acids), whereas such a link is less clear for aromas, which often result from the interplay between multiple volatile compounds. We also find that our models are best at predicting acidity and alcohol, likely because there is a direct relation between the measured chemical compounds (acids and ethanol) and the corresponding perceived sensorial attribute (acidity and alcohol), and because even untrained consumers are generally able to recognize these flavors and aromas.

The predictions of our final models, trained on review data, hold even for blind tastings with small groups of trained tasters, as demonstrated by our ability to validate specific compounds as drivers of beer flavor and appreciation. Since adding a single compound to the extent of a noticeable difference may result in an unbalanced flavor profile, we specifically tested our identified key drivers as a combination of compounds. While this approach does not allow us to validate if a particular single compound would affect flavor and/or appreciation, our experiments do show that this combination of compounds increases consumer appreciation.

It is important to stress that, while it represents an important step forward, our approach still has several major limitations. A key weakness of the GBR model architecture is that amongst co-correlating variables, the largest main effect is consistently preferred for model building. As a result, co-correlating variables often have artificially low importance scores, both for impurity and SHAP-based methods, like we observed in the comparison to the more randomized Extra Trees models. This implies that chemicals identified as key drivers of a specific sensory feature by GBR might not be the true causative compounds, but rather co-correlate with the actual causative chemical. For example, the high importance of ethyl acetate could be (partially) attributed to the total ester content, ethanol or ethyl hexanoate (rho=0.77, rho=0.72 and rho=0.68), while ethyl phenylacetate could hide the importance of prenyl isobutyrate and ethyl benzoate (rho=0.77 and rho=0.76). Expanding our GBR model to include beer style as a parameter did not yield additional power or insight. This is likely due to style-specific chemical signatures, such as iso-alpha acids and lactic acid, that implicitly convey style information to the original model, as well as the smaller sample size per style, limiting the power to uncover style-specific patterns. This can be partly attributed to the curse of dimensionality, where the high number of parameters results in the models mainly incorporating single parameter effects, rather than complex interactions such as style-dependent effects 67 . A larger number of samples may overcome some of these limitations and offer more insight into style-specific effects. On the other hand, beer style is not a rigid scientific classification, and beers within one style often differ a lot, which further complicates the analysis of style as a model factor.

Our study is limited to beers from Belgian breweries. Although these beers cover a large portion of the beer styles available globally, some beer styles and consumer patterns may be missing, while other features might be overrepresented. For example, many Belgian ales exhibit yeast-driven flavor profiles, which is reflected in the chemical drivers of appreciation discovered by this study. In future work, expanding the scope to include diverse markets and beer styles could lead to the identification of even more drivers of appreciation and better models for special niche products that were not present in our beer set.

In addition to inherent limitations of GBR models, there are also some limitations associated with studying food aroma. Even if our chemical analyses measured most of the known aroma compounds, the total number of flavor compounds in complex foods like beer is still larger than the subset we were able to measure in this study. For example, hop-derived thiols, that influence flavor at very low concentrations, are notoriously difficult to measure in a high-throughput experiment. Moreover, consumer perception remains subjective and prone to biases that are difficult to avoid. It is also important to stress that the models are still immature and that more extensive datasets will be crucial for developing more complete models in the future. Besides more samples and parameters, our dataset does not include any demographic information about the tasters. Including such data could lead to better models that grasp external factors like age and culture. Another limitation is that our set of beers consists of high-quality end-products and lacks beers that are unfit for sale, which limits the current model in accurately predicting products that are appreciated very badly. Finally, while models could be readily applied in quality control, their use in sensory science and product development is restrained by their inability to discern causal relationships. Given that the models cannot distinguish compounds that genuinely drive consumer perception from those that merely correlate, validation experiments are essential to identify true causative compounds.

Despite the inherent limitations, dissection of our models enabled us to pinpoint specific molecules as potential drivers of beer aroma and consumer appreciation, including compounds that were unexpected and would not have been identified using standard approaches. Important drivers of beer appreciation uncovered by our models include protein levels, ethyl acetate, ethyl phenyl acetate and lactic acid. Currently, many brewers already use lactic acid to acidify their brewing water and ensure optimal pH for enzymatic activity during the mashing process. Our results suggest that adding lactic acid can also improve beer appreciation, although its individual effect remains to be tested. Interestingly, ethanol appears to be unnecessary to improve beer appreciation, both for blond beer and alcohol-free beer. Given the growing consumer interest in alcohol-free beer, with a predicted annual market growth of >7% 84 , it is relevant for brewers to know what compounds can further increase consumer appreciation of these beers. Hence, our model may readily provide avenues to further improve the flavor and consumer appreciation of both alcoholic and non-alcoholic beers, which is generally considered one of the key challenges for future beer production.

Whereas we see a direct implementation of our results for the development of superior alcohol-free beverages and other food products, our study can also serve as a stepping stone for the development of novel alcohol-containing beverages. We want to echo the growing body of scientific evidence for the negative effects of alcohol consumption, both on the individual level by the mutagenic, teratogenic and carcinogenic effects of ethanol 85 , 86 , as well as the burden on society caused by alcohol abuse and addiction. We encourage the use of our results for the production of healthier, tastier products, including novel and improved beverages with lower alcohol contents. Furthermore, we strongly discourage the use of these technologies to improve the appreciation or addictive properties of harmful substances.

The present work demonstrates that despite some important remaining hurdles, combining the latest developments in chemical analyses, sensory analysis and modern machine learning methods offers exciting avenues for food chemistry and engineering. Soon, these tools may provide solutions in quality control and recipe development, as well as new approaches to sensory science and flavor research.

Beer selection

250 commercial Belgian beers were selected to cover the broad diversity of beer styles and corresponding diversity in chemical composition and aroma. See Supplementary Fig.  S1 .

Chemical dataset

Sample preparation.

Beers within their expiration date were purchased from commercial retailers. Samples were prepared in biological duplicates at room temperature, unless explicitly stated otherwise. Bottle pressure was measured with a manual pressure device (Steinfurth Mess-Systeme GmbH) and used to calculate CO 2 concentration. The beer was poured through two filter papers (Macherey-Nagel, 500713032 MN 713 ¼) to remove carbon dioxide and prevent spontaneous foaming. Samples were then prepared for measurements by targeted Headspace-Gas Chromatography-Flame Ionization Detector/Flame Photometric Detector (HS-GC-FID/FPD), Headspace-Solid Phase Microextraction-Gas Chromatography-Mass Spectrometry (HS-SPME-GC-MS), colorimetric analysis, enzymatic analysis, Near-Infrared (NIR) analysis, as described in the sections below. The mean values of biological duplicates are reported for each compound.

HS-GC-FID/FPD

HS-GC-FID/FPD (Shimadzu GC 2010 Plus) was used to measure higher alcohols, acetaldehyde, esters, 4-vinyl guaicol, and sulfur compounds. Each measurement comprised 5 ml of sample pipetted into a 20 ml glass vial containing 1.75 g NaCl (VWR, 27810.295). 100 µl of 2-heptanol (Sigma-Aldrich, H3003) (internal standard) solution in ethanol (Fisher Chemical, E/0650DF/C17) was added for a final concentration of 2.44 mg/L. Samples were flushed with nitrogen for 10 s, sealed with a silicone septum, stored at −80 °C and analyzed in batches of 20.

The GC was equipped with a DB-WAXetr column (length, 30 m; internal diameter, 0.32 mm; layer thickness, 0.50 µm; Agilent Technologies, Santa Clara, CA, USA) to the FID and an HP-5 column (length, 30 m; internal diameter, 0.25 mm; layer thickness, 0.25 µm; Agilent Technologies, Santa Clara, CA, USA) to the FPD. N 2 was used as the carrier gas. Samples were incubated for 20 min at 70 °C in the headspace autosampler (Flow rate, 35 cm/s; Injection volume, 1000 µL; Injection mode, split; Combi PAL autosampler, CTC analytics, Switzerland). The injector, FID and FPD temperatures were kept at 250 °C. The GC oven temperature was first held at 50 °C for 5 min and then allowed to rise to 80 °C at a rate of 5 °C/min, followed by a second ramp of 4 °C/min until 200 °C kept for 3 min and a final ramp of (4 °C/min) until 230 °C for 1 min. Results were analyzed with the GCSolution software version 2.4 (Shimadzu, Kyoto, Japan). The GC was calibrated with a 5% EtOH solution (VWR International) containing the volatiles under study (Supplementary Table  S7 ).

HS-SPME-GC-MS

HS-SPME-GC-MS (Shimadzu GCMS-QP-2010 Ultra) was used to measure additional volatile compounds, mainly comprising terpenoids and esters. Samples were analyzed by HS-SPME using a triphase DVB/Carboxen/PDMS 50/30 μm SPME fiber (Supelco Co., Bellefonte, PA, USA) followed by gas chromatography (Thermo Fisher Scientific Trace 1300 series, USA) coupled to a mass spectrometer (Thermo Fisher Scientific ISQ series MS) equipped with a TriPlus RSH autosampler. 5 ml of degassed beer sample was placed in 20 ml vials containing 1.75 g NaCl (VWR, 27810.295). 5 µl internal standard mix was added, containing 2-heptanol (1 g/L) (Sigma-Aldrich, H3003), 4-fluorobenzaldehyde (1 g/L) (Sigma-Aldrich, 128376), 2,3-hexanedione (1 g/L) (Sigma-Aldrich, 144169) and guaiacol (1 g/L) (Sigma-Aldrich, W253200) in ethanol (Fisher Chemical, E/0650DF/C17). Each sample was incubated at 60 °C in the autosampler oven with constant agitation. After 5 min equilibration, the SPME fiber was exposed to the sample headspace for 30 min. The compounds trapped on the fiber were thermally desorbed in the injection port of the chromatograph by heating the fiber for 15 min at 270 °C.

The GC-MS was equipped with a low polarity RXi-5Sil MS column (length, 20 m; internal diameter, 0.18 mm; layer thickness, 0.18 µm; Restek, Bellefonte, PA, USA). Injection was performed in splitless mode at 320 °C, a split flow of 9 ml/min, a purge flow of 5 ml/min and an open valve time of 3 min. To obtain a pulsed injection, a programmed gas flow was used whereby the helium gas flow was set at 2.7 mL/min for 0.1 min, followed by a decrease in flow of 20 ml/min to the normal 0.9 mL/min. The temperature was first held at 30 °C for 3 min and then allowed to rise to 80 °C at a rate of 7 °C/min, followed by a second ramp of 2 °C/min till 125 °C and a final ramp of 8 °C/min with a final temperature of 270 °C.

Mass acquisition range was 33 to 550 amu at a scan rate of 5 scans/s. Electron impact ionization energy was 70 eV. The interface and ion source were kept at 275 °C and 250 °C, respectively. A mix of linear n-alkanes (from C7 to C40, Supelco Co.) was injected into the GC-MS under identical conditions to serve as external retention index markers. Identification and quantification of the compounds were performed using an in-house developed R script as described in Goelen et al. and Reher et al. 87 , 88 (for package information, see Supplementary Table  S8 ). Briefly, chromatograms were analyzed using AMDIS (v2.71) 89 to separate overlapping peaks and obtain pure compound spectra. The NIST MS Search software (v2.0 g) in combination with the NIST2017, FFNSC3 and Adams4 libraries were used to manually identify the empirical spectra, taking into account the expected retention time. After background subtraction and correcting for retention time shifts between samples run on different days based on alkane ladders, compound elution profiles were extracted and integrated using a file with 284 target compounds of interest, which were either recovered in our identified AMDIS list of spectra or were known to occur in beer. Compound elution profiles were estimated for every peak in every chromatogram over a time-restricted window using weighted non-negative least square analysis after which peak areas were integrated 87 , 88 . Batch effect correction was performed by normalizing against the most stable internal standard compound, 4-fluorobenzaldehyde. Out of all 284 target compounds that were analyzed, 167 were visually judged to have reliable elution profiles and were used for final analysis.

Discrete photometric and enzymatic analysis

Discrete photometric and enzymatic analysis (Thermo Scientific TM Gallery TM Plus Beermaster Discrete Analyzer) was used to measure acetic acid, ammonia, beta-glucan, iso-alpha acids, color, sugars, glycerol, iron, pH, protein, and sulfite. 2 ml of sample volume was used for the analyses. Information regarding the reagents and standard solutions used for analyses and calibrations is included in Supplementary Table  S7 and Supplementary Table  S9 .

NIR analyses

NIR analysis (Anton Paar Alcolyzer Beer ME System) was used to measure ethanol. Measurements comprised 50 ml of sample, and a 10% EtOH solution was used for calibration.

Correlation calculations

Pairwise Spearman Rank correlations were calculated between all chemical properties.

Sensory dataset

Trained panel.

Our trained tasting panel consisted of volunteers who gave prior verbal informed consent. All compounds used for the validation experiment were of food-grade quality. The tasting sessions were approved by the Social and Societal Ethics Committee of the KU Leuven (G-2022-5677-R2(MAR)). All online reviewers agreed to the Terms and Conditions of the RateBeer website.

Sensory analysis was performed according to the American Society of Brewing Chemists (ASBC) Sensory Analysis Methods 90 . 30 volunteers were screened through a series of triangle tests. The sixteen most sensitive and consistent tasters were retained as taste panel members. The resulting panel was diverse in age [22–42, mean: 29], sex [56% male] and nationality [7 different countries]. The panel developed a consensus vocabulary to describe beer aroma, taste and mouthfeel. Panelists were trained to identify and score 50 different attributes, using a 7-point scale to rate attributes’ intensity. The scoring sheet is included as Supplementary Data  3 . Sensory assessments took place between 10–12 a.m. The beers were served in black-colored glasses. Per session, between 5 and 12 beers of the same style were tasted at 12 °C to 16 °C. Two reference beers were added to each set and indicated as ‘Reference 1 & 2’, allowing panel members to calibrate their ratings. Not all panelists were present at every tasting. Scores were scaled by standard deviation and mean-centered per taster. Values are represented as z-scores and clustered by Euclidean distance. Pairwise Spearman correlations were calculated between taste and aroma sensory attributes. Panel consistency was evaluated by repeating samples on different sessions and performing ANOVA to identify differences, using the ‘stats’ package (v4.2.2) in R (for package information, see Supplementary Table  S8 ).

Online reviews from a public database

The ‘scrapy’ package in Python (v3.6) (for package information, see Supplementary Table  S8 ). was used to collect 232,288 online reviews (mean=922, min=6, max=5343) from RateBeer, an online beer review database. Each review entry comprised 5 numerical scores (appearance, aroma, taste, palate and overall quality) and an optional review text. The total number of reviews per reviewer was collected separately. Numerical scores were scaled and centered per rater, and mean scores were calculated per beer.

For the review texts, the language was estimated using the packages ‘langdetect’ and ‘langid’ in Python. Reviews that were classified as English by both packages were kept. Reviewers with fewer than 100 entries overall were discarded. 181,025 reviews from >6000 reviewers from >40 countries remained. Text processing was done using the ‘nltk’ package in Python. Texts were corrected for slang and misspellings; proper nouns and rare words that are relevant to the beer context were specified and kept as-is (‘Chimay’,’Lambic’, etc.). A dictionary of semantically similar sensorial terms, for example ‘floral’ and ‘flower’, was created and collapsed together into one term. Words were stemmed and lemmatized to avoid identifying words such as ‘acid’ and ‘acidity’ as separate terms. Numbers and punctuation were removed.

Sentences from up to 50 randomly chosen reviews per beer were manually categorized according to the aspect of beer they describe (appearance, aroma, taste, palate, overall quality—not to be confused with the 5 numerical scores described above) or flagged as irrelevant if they contained no useful information. If a beer contained fewer than 50 reviews, all reviews were manually classified. This labeled data set was used to train a model that classified the rest of the sentences for all beers 91 . Sentences describing taste and aroma were extracted, and term frequency–inverse document frequency (TFIDF) was implemented to calculate enrichment scores for sensorial words per beer.

The sex of the tasting subject was not considered when building our sensory database. Instead, results from different panelists were averaged, both for our trained panel (56% male, 44% female) and the RateBeer reviews (70% male, 30% female for RateBeer as a whole).

Beer price collection and processing

Beer prices were collected from the following stores: Colruyt, Delhaize, Total Wine, BeerHawk, The Belgian Beer Shop, The Belgian Shop, and Beer of Belgium. Where applicable, prices were converted to Euros and normalized per liter. Spearman correlations were calculated between these prices and mean overall appreciation scores from RateBeer and the taste panel, respectively.

Pairwise Spearman Rank correlations were calculated between all sensory properties.

Machine learning models

Predictive modeling of sensory profiles from chemical data.

Regression models were constructed to predict (a) trained panel scores for beer flavors and quality from beer chemical profiles and (b) public reviews’ appreciation scores from beer chemical profiles. Z-scores were used to represent sensory attributes in both data sets. Chemical properties with log-normal distributions (Shapiro-Wilk test, p  <  0.05 ) were log-transformed. Missing chemical measurements (0.1% of all data) were replaced with mean values per attribute. Observations from 250 beers were randomly separated into a training set (70%, 175 beers) and a test set (30%, 75 beers), stratified per beer style. Chemical measurements (p = 231) were normalized based on the training set average and standard deviation. In total, three linear regression-based models: linear regression with first-order interaction terms (LR), lasso regression with first-order interaction terms (Lasso) and partial least squares regression (PLSR); five decision tree models, Adaboost regressor (ABR), Extra Trees (ET), Gradient Boosting regressor (GBR), Random Forest (RF) and XGBoost regressor (XGBR); one support vector machine model (SVR) and one artificial neural network model (ANN) were trained. The models were implemented using the ‘scikit-learn’ package (v1.2.2) and ‘xgboost’ package (v1.7.3) in Python (v3.9.16). Models were trained, and hyperparameters optimized, using five-fold cross-validated grid search with the coefficient of determination (R 2 ) as the evaluation metric. The ANN (scikit-learn’s MLPRegressor) was optimized using Bayesian Tree-Structured Parzen Estimator optimization with the ‘Optuna’ Python package (v3.2.0). Individual models were trained per attribute, and a multi-output model was trained on all attributes simultaneously.

Model dissection

GBR was found to outperform other methods, resulting in models with the highest average R 2 values in both trained panel and public review data sets. Impurity-based rankings of the most important predictors for each predicted sensorial trait were obtained using the ‘scikit-learn’ package. To observe the relationships between these chemical properties and their predicted targets, partial dependence plots (PDP) were constructed for the six most important predictors of consumer appreciation 74 , 75 .

The ‘SHAP’ package in Python (v0.41.0) was implemented to provide an alternative ranking of predictor importance and to visualize the predictors’ effects as a function of their concentration 68 .

Validation of causal chemical properties

To validate the effects of the most important model features on predicted sensory attributes, beers were spiked with the chemical compounds identified by the models and descriptive sensory analyses were carried out according to the American Society of Brewing Chemists (ASBC) protocol 90 .

Compound spiking was done 30 min before tasting. Compounds were spiked into fresh beer bottles, that were immediately resealed and inverted three times. Fresh bottles of beer were opened for the same duration, resealed, and inverted thrice, to serve as controls. Pairs of spiked samples and controls were served simultaneously, chilled and in dark glasses as outlined in the Trained panel section above. Tasters were instructed to select the glass with the higher flavor intensity for each attribute (directional difference test 92 ) and to select the glass they prefer.

The final concentration after spiking was equal to the within-style average, after normalizing by ethanol concentration. This was done to ensure balanced flavor profiles in the final spiked beer. The same methods were applied to improve a non-alcoholic beer. Compounds were the following: ethyl acetate (Merck KGaA, W241415), ethyl hexanoate (Merck KGaA, W243906), isoamyl acetate (Merck KGaA, W205508), phenethyl acetate (Merck KGaA, W285706), ethanol (96%, Colruyt), glycerol (Merck KGaA, W252506), lactic acid (Merck KGaA, 261106).

Significant differences in preference or perceived intensity were determined by performing the two-sided binomial test on each attribute.

FAQs About Research Paper Writing Services

How do essay writing services work.

If you’ve never ordered from an essay writing service before, then you might not know what to expect — or where to start. More and more college students are turning to these sites to help them with the increasing number of essays that they are assigned every semester — but how do essay writing services work?

The research paper writing services connect you with professional and academic writers, who are either employed by the site or work as self-employed freelancers, to work on your paper. The professional research paper writer will see the subject area you request, the number of words or pages that are needed, the deadline for the paper, and other information that you provide.

The research paper helper may contact you to request additional information, or to keep you updated on the progress of your paper. Because the writer that has been assigned to your paper will have knowledge of your subject area, they will use a variety of specialized resources to write your assignment.

Once your paper has been completed, you will receive a PDF draft from the professional writer — this is the stage where you can ask for any revisions to be made. If you’re happy with what has been written, the full version of the paper will be released to you, and is officially all yours!

Are research paper writing websites legit?

Contrary to popular belief, there is nothing illegal about using a custom research paper writing website. As long as you follow the correct procedures of your university, you also can’t get into trouble for academic misconduct.

Writers who work for research paper writing services are normal human beings, who happen to have a passion and a talent for writing. Usually, these writers are paid a large percentage of what you pay to the research paper help site — sometimes, they are also paid to work specific hours.

Before you start spending money though, it’s important to verify the integrity of the site you’re looking to use. The essay writing services space has exploded in popularity in recent years, which means that some people want to take advantage of this. There are plenty of sites that will take your payment and run, leaving you out of pocket and without an essay for your upcoming deadline.

Make sure to check the reviews of the sites you’re looking at — especially those on impartial sites such as TrustPilot. It can also be helpful to look at the About Us section on the website, to learn more about the company. Finally, if it seems too good to be true, it likely is — don’t trust sites that are charging something like $10 for thousands of words, with a same-day turnaround.

Can I entrust someone to write my research paper? Is it safe?

Research paper assistance sites mentioned on this list are 100% safe to use, and you don’t need to worry about any negative repercussions from using their services. The most reputable sites will have a confidentiality policy, where your interaction with their research paper writers will remain anonymous. Nobody will know you have used the site unless you share this information yourself.

Most sites put their professional paper writers through strict verification processes — this ensures not only their writing ability, but also that they are a real and trustworthy person. They may ask their writers to provide government issued ID, and proof of their employment or academic qualifications.

You may also be concerned about if your payment is secure when using a term paper writing service — many of these sites use secure payment methods such as PayPal, Google Pay, Apple Pay and more. There is also support for a number of international, fee-free payment options.

A good research paper writing service will also have stringent anti-plagiarism measures. This includes checking the finished product a number of times through different services, and some sites will have their own purpose-built plagiarism checkers.

Will my essay be plagiarism-free?

One of the main concerns when ordering an essay from a writing service is whether it will be flagged for plagiarism. Having this happen to one of your assignments can get you into serious trouble. You may be investigated by your school’s academic misconduct department, and you could even be expelled from your high school, university, or college.

Professional research paper services include a guarantee of plagiarism-free content. Your paper will contain only unique content, with no copy-pasted information. All sources will also be properly referenced in the style that you request.

To achieve this, sites use plagiarism checkers from a variety of sources. Many custom research papers and term papers are checked multiple times, and every effort is taken to reduce the similarity percentage of the finished product.

Specifically, many sites will ensure that their research papers pass the plagiarism check enforced by Turnitin — one of the most popular assignment submission platforms that many universities use. The platform has a strict plagiarism checker that will flag an assignment if it is above a certain similarity percentage.

You can be confident that your essay will be plagiarism-free when ordering from a paper writing service; and if it isn’t, you may be entitled for a free refund under their money back guarantee.

How much does it cost to hire professional research paper writers?

The price to buy a research paper online will vary depending on a few factors. Many sites will allow you to input your basic requirements, and give you an estimation of the price based on this. The factors that can increase or decrease the cost of your paper include its length, the deadline for submission, the education level, and sometimes the subject area.

The specific cost of paying for an essay may be calculated per page, or per 100 words. In most cases, our research found that the standard price for a 1 page, high-school level essay with a 2 week turnaround was between $10 and $12.

If you want to save on your research paper, then make sure to request the services of a writing site well in advance — the more time you give them to complete your paper, the less it will cost.

Can you get caught using term paper writing services?

This is a common concern for people who are looking to find a research paper service to write academic papers for them. Plagiarism not only includes using uncited sources from the internet, but also trying to pass off someone else’s work as your own. As we covered earlier, this can get you into a lot of trouble.

When buying an essay to use as a model answer, as reference material, or ideas, you cannot get caught or punished for using it. Your professors won’t need to see the essay that you bought, and you won’t need to cite your usage of it; because for all intents and purposes, it does not exist.

Things become less clear when you consider, or intend to submit a research paper that you bought. Many sites do not encourage this, and it should not be the main reason that you look for a service to write your essay for you. You have a much higher chance of being caught for submitting a bought research paper as your own, but you may also get away with it … do so at your own risk!

So, to conclude, our overall choice for the best research paper writing service is PaperHelp. We’re crowning them as our winner based on their high quality services, low prices, and fast delivery. Their customer reviews and testimonials show that people trust them to deliver on-time, and to take attention to detail in their work.

Whether you’re looking for inspiration, editing and proofreading, or just expert advice on your research paper, you can be sure of receiving an A+ service from PaperHelp.
