Research Paper vs. Research Article: What’s the Difference?

Research papers and research articles are two different forms of academic writing, with distinct characteristics. Although they share some similarities in terms of format and purpose, there are important distinctions between the two types that should be understood by students who wish to write either form effectively. This article will explain the differences between a research paper and a research article, outlining their unique features and applications. Furthermore, it will offer guidance on how best to approach each type when crafting an effective piece for scholarly consumption.

Research Paper vs. Research Article

The academic world is full of a variety of different writing styles, each with its own unique purpose and goals. Two particularly important forms are the research paper and the research article. Each has their own distinct features that make them uniquely suited to certain tasks within academia – let’s take a closer look at what sets them apart from one another!

A research paper , as you might expect, presents in-depth analysis on an issue or topic using evidence gathered through primary sources such as field work, laboratory experiments, surveys, interviews etc., whereas a research article , typically published in scholarly journals or online publications like websites & blogs addresses specific findings derived from secondary sources like books or other papers related to said subject matter. The former requires more effort & dedication from the author due to it being time consuming & involving careful structuring along with rigorous citation format adherence; while the latter focuses mainly on providing succinct yet comprehensive overviews regarding topics which have already been extensively discussed by experts in depth previously elsewhere – taking into account present day developments/breakthroughs if necessary before finally offering opinionated conclusions pertaining to said subjects.

Exploring the Characteristics of a Research Paper and Article

• Research paper:
• Research article:

A research paper is an extended form of writing that presents and supports an argument on a particular topic. It provides evidence for the opinion or idea in the form of facts, data, analysis, opinions from authorities in specific fields etc. The objective is to make original claims based on careful evaluation of information available on a given subject. It requires significant effort as one needs to be able to distill complex topics into concisely articulated points that are supported by solid evidence.

On the other hand, a research article is usually written for publication either online or printed through journals or magazines. These articles have been peer-reviewed which means they follow certain academic standards established within their discipline while presenting factual conclusions related to ongoing debates and arguments raised by preceding works. They generally provide new insight into existing knowledge rather than build upon it using more primary sources such as surveys and experiments conducted independently by authors themselves.

Comparison of Structure, Content and Writing Styles between Research Papers and Articles For the purpose of scholarly communication, both research papers and articles play a vital role. Though there is no hard-and-fast rule that distinguishes them from each other in terms of structure or content, they usually differ significantly in their style. In comparison to research papers, articles typically have a much smaller length requirement. They can range anywhere from 1 page to as many as 30 pages depending on the journal guidelines – making them more accessible for readers who are seeking concise summaries with quick insights into topics. On the contrary, research papers tend to be longer documents that delve deeper into an issue by providing extensive background information; detailed analysis; arguments bolstered by sources such as peer-reviewed journals or interviews; conclusion sections tying up any loose ends etc.

• Research Papers: Longer documents which provide extensive coverage about an issue.
• Articles: Short pieces covering high level overviews without going too deep.

When it comes down to writing styles used for these two types of documents – Authors generally follow formal academic language while creating research paper whereas article writers tend to use more casual tones in order to appeal wider audience groups. Additionally authors will often adopt conversational elements like anecdotes when crafting articles so that readers can get better understanding about specific points being discussed within context.

Formal vs. Informal Study: A Critical Analysis The choice between conducting a formal or informal study may be difficult for researchers due to the advantages and drawbacks of each approach. Depending on their research topic, scientists must carefully weigh up the pros and cons before deciding which course of action is most suitable for them.

A formal study , as conducted in many research papers and articles, often requires more time-consuming effort from researchers than an informal one because it involves using specific methodologies such as surveys, interviews, experiments etc., gathering quantitative data that needs to be statistically analyzed by employing reliable statistical methods. On the other hand, a formal investigation allows researchers to obtain objective information from well-defined populations about predetermined variables through systematic procedures that can yield precise results with larger external validity – making it possible to make generalizations beyond those studied in this particular case.

Conversely, an informal study , also known as participant observation or field work requires less structured approaches where collecting qualitative data is usually achieved via conversations with informants instead of strict instrumentations; thus allowing greater interaction between researcher and subjects resulting in increased understanding of contextually situated phenomena within its natural setting rather than artificially created ones used in laboratories’ studies – leading to deeper insights into complex social processes . Also noteworthy is its lower financial cost when compared against highly expensive equipment needed for undertaking large scale scientific investigations.. However despite yielding valuable first person accounts which might not have been obtained elsewhere , such observations are sometimes criticized due challenges related accuracy given reliance on subjective interpretations while generating evidence without significant use of control variables .

Selecting the Optimal Approach for Academic Assignments When it comes to completing academic assignments, there are various approaches one can take. In order to ensure success and optimal results, it is important that students consider all of their options carefully before making a choice.

Research papers often require extensive research and careful consideration when selecting an approach. Using primary sources such as books or peer-reviewed articles may be more reliable in comparison to secondary sources such as websites or blogs which are usually less credible due to lack of credibility checks by professionals within the field. Additionally, data analysis can help strengthen arguments while also adding clarity to any work produced during the course of completion; however, understanding how best utilize this analytical tool effectively requires additional practice and experience on behalf of the student undertaking it. For research articles, detailed knowledge about particular topics may lead towards better outcomes but general familiarity with content areas is sufficient enough for success here too. The key lies in being able identify appropriate methods quickly through use critical thinking skills coupled with clear objectives pertaining specifically each assignment itself at hand prior its execution – this way mistakes are avoided thus delivering quality results each time..

Comparative Analyses of Scholarly Outputs

• Scholarly output, such as research papers and articles, are subject to scrutiny when attempting to make comparisons.
• Due to the differences between these two types of outputs, it can be difficult or impossible to achieve a true comparison.

Comparing scholarly outputs is not always possible due to their distinct forms. Research papers typically have more depth than an article on the same topic which may mean that even though both documents might discuss similar topics in some aspects they will differ greatly in others. Furthermore, the format of each type of document contributes further complexities; for example, a research paper is often much longer and requires extensive background information before any conclusions can be drawn while articles tend towards presenting results with little room left for interpretation. The style used by authors also adds difficulty; many times research papers include complex jargon necessary for understanding specific points whereas an article strives for simplicity so its target audience can comprehend all material without excessive effort. These limitations prevent proper analysis from being done since one piece could provide certain details while another provides only bits related thereto leading readers into confusion if attempting to compare them directly despite intentions otherwise. It then becomes clear that academic pieces should instead remain separate entities rather than compared against each other since doing so would lead only too frustration given current constraints therein found.

Exploring the Similarities and Differences Between Academic Writings

As our understanding of academic writings continues to evolve, so too must our appreciation for both their similarities and differences. From research papers to research articles, it is important to consider how each one contributes unique insight into a given topic or issue.

The research paper and research article may look similar on the surface, but upon closer inspection one can see significant differences in their format, purpose, and audience. The key distinctions between these two forms of written work are scope of content covered, type of analysis used to draw conclusions or develop knowledge from data or evidence presented, and intended readership. Ultimately, understanding the essential characteristics that distinguish a research paper from a research article is beneficial for anyone who produces such texts as it will help them craft an effective product that aligns with its desired purposes.

How Academic Writing Differs from Other Forms of Writing

#scribendiinc

Written by  Scribendi

Have you ever wondered how academic writing stacks up against different styles of writing? If you have, then you're in good company, as many curious minds have pondered that same distinction. Let's get to it!

Formal Language versus Informal Language

Academic writing should use formal language that minimizes the use of contractions and colloquialisms and avoids slang terminology whenever possible. Casual language should only be used for emphasis.

Further, academic writing generally does not employ first person pronouns like "I" or "we," but different styles of writing do offer varying degrees of flexibility when it comes to the use of language, with a diverse range of informal elements sanctioned among different styles of writing.  

Check out the image below to further explore the differences between textspeak, informal language, and formal language!

Structure and Form

Style guides like the Publication Manual of the American Psychological Association (APA) and the Chicago Manual of Style are quintessential resources for scholars engaging in academic writing, with different style guides used for different fields of academia. These style guides standardize how references should be presented and how a document should be formatted, considering things like the margins, headings, typeface, and a myriad of other elements; some guides even prescribe the kind of language to be used for various circumstances encountered most frequently within the field.

All forms of academic writing will employ a structure that should allow the information presented to flow logically from one section to the next, regardless of the segments or formatting details used according to different styles of writing. For example, a scientific research article will typically include sections for the abstract, introduction, methods, analysis, results, and conclusions, whereas a paper written for the humanities will use a drastically different framework that can vary between artistic disciplines.

Different styles of writing contain various essential structural elements. This means that some styles, such as creative writing, grant significantly more freedom to the author than other styles, such as the style used for writing engineering documents.

The tone used to communicate ideas will significantly affect how readers interpret those ideas. It's vital that different styles of writing adopt different tones appropriate for the respective target audiences.

It's especially crucial within academic writing to eliminate all personal biases, both explicit and implicit. Academic writing must display objectivity. It's often best that academic writing avoids rhetorical tactics, like sweeping generalizations and emotional arguments, as this will ensure the highest degree of objectivity expected from academic writing.

At its core, academic writing should be clear, succinct, and objective; the exact criteria for these qualities differ among different styles of writing, but without these elements, the credibility of academic writing is often shaky.

The tone, language, and formality of academic writing will all depend on the target audience . As such, the target audience is a crucial consideration for effective academic writing.

In an academic setting, your audience could comprise researchers, professors, and/or experts in the field, but a casual piece might target your family and friends. The way we speak to figures of authority is very different from how we speak to siblings or friends, and communicating with these different groups when writing is no different; the word choices used in academic writing should suit the audience just as much as a person's vocabulary and gestures might shift for face-to-face communication according to these different groups.

For example, when the public is the intended audience for a piece of academic writing, it's probably a good idea to use simple language to explain any tricky terms used in the document. You might even consider substituting the academic jargon for another phrase more easily understood by the masses. This is true for all different styles of writing. The audience needs to understand what has been written!

If you're uncertain whether a particular term might be appropriate for your audience, try consulting a friend who is unfamiliar with the topic. This should clearly indicate how easy it might be for the average person to understand the concept.

The following piece of advice applies to all different styles of writing: leave time to edit! Regardless of the document, your work should be entirely free from errors. Proofreading for things like grammatical mistakes and punctuation errors and editing for elements such as the word choices and sentence structures will ensure that the writing is cohesive and clear. Further revision will ensure that unsightly grammatical errors and embarrassing typos never appear before the unforgiving public eye.

Types of journal articles

It is helpful to familiarise yourself with the different types of articles published by journals. Although it may appear there are a large number of types of articles published due to the wide variety of names they are published under, most articles published are one of the following types; Original Research, Review Articles, Short reports or Letters, Case Studies, Methodologies.

Original Research:

This is the most common type of journal manuscript used to publish full reports of data from research. It may be called an  Original Article, Research Article, Research, or just  Article, depending on the journal. The Original Research format is suitable for many different fields and different types of studies. It includes full Introduction, Methods, Results, and Discussion sections.

Short reports or Letters:

These papers communicate brief reports of data from original research that editors believe will be interesting to many researchers, and that will likely stimulate further research in the field. As they are relatively short the format is useful for scientists with results that are time sensitive (for example, those in highly competitive or quickly-changing disciplines). This format often has strict length limits, so some experimental details may not be published until the authors write a full Original Research manuscript. These papers are also sometimes called Brief communications .

Review Articles:

Review Articles provide a comprehensive summary of research on a certain topic, and a perspective on the state of the field and where it is heading. They are often written by leaders in a particular discipline after invitation from the editors of a journal. Reviews are often widely read (for example, by researchers looking for a full introduction to a field) and highly cited. Reviews commonly cite approximately 100 primary research articles.

TIP: If you would like to write a Review but have not been invited by a journal, be sure to check the journal website as some journals to not consider unsolicited Reviews. If the website does not mention whether Reviews are commissioned it is wise to send a pre-submission enquiry letter to the journal editor to propose your Review manuscript before you spend time writing it.  

Case Studies:

These articles report specific instances of interesting phenomena. A goal of Case Studies is to make other researchers aware of the possibility that a specific phenomenon might occur. This type of study is often used in medicine to report the occurrence of previously unknown or emerging pathologies.

Methodologies or Methods

These articles present a new experimental method, test or procedure. The method described may either be completely new, or may offer a better version of an existing method. The article should describe a demonstrable advance on what is currently available.

Academic vs. Nonacademic Writing Styles

Academic and nonacademic writing are distinct styles with different characteristics and purposes. Academic writing is formal, evidence-based, and aimed at scholarly audiences, while nonacademic writing is informal, personal, and intended for a wider audience. Choosing the appropriate style depends on the target audience and the writer's specific purpose.

Updated on September 5, 2023

Academic and nonacademic writing are two different writing styles with distinct characteristics and purposes. Each style has its own conventions and best practices. Writers must understand and adhere to these conventions to best communicate with their intended audience.

The key factor to keep in mind here is your target audience .

Academic writing

The language used in academic writing is precise and often technical. It follows a standard structure, which typically includes introduction, background, methodology, results, discussion and conclusion sections. 

Academic writing generally includes a list of cited references and figures showing the data and data analyses performed over the course of research. A few examples of academic writing include journal articles, research papers, and theses /dissertations.

Characteristics of academic writing

The fundamental characteristics of academic writing are described as follows:

• Clear and concise : Academic writing is clear and concisely written. The use of jargon and excessive wordiness are not effective means of communicating through academic writing.
• Evidence-based content : Academic writing is based on evidence and research. Credible sources are used and they are cited appropriately.
• Formal tone : Academic writing uses a formal tone and avoids contractions, colloquial language, and informal expressions.
• Structured writing : Academic writing has a clear structure, such as introduction, methodology, and conclusion sections.
• A uniform citation style : Different fields have their own citation styles, and it is important to follow the specific citation style required by your institution or field.
• Proofread and edit : Always proofread and edit your work before submitting it for review. For assistance with this step, AJE can help with all of your proofreading, editing and translation needs. 
• Avoid plagiarism : Plagiarism can be avoided by properly citing sources, paraphrasing, and summarizing.

To communicate with a general audience, nonacademic writing styles are the best bet. In contrast to academic writing, nonacademic writing has an informal tone, a personal approach, and often uses emotions to convey the message. Nonacademic writing is aimed at a general audience and is used to entertain, inform, and persuade people. The language used in nonacademic writing is not usually technical and is considered to be accessible to a wider audience. Examples of nonacademic writing include newspaper articles, blog posts, and creative writing, such as fiction and poetry.

Characteristics of nonacademic writing

Nonacademic writing is not intended for an academic audience or purpose. Some of the characteristics of nonacademic writing are described as follows:

• Colloquial language : Nonacademic writing often uses colloquial language, slang, and contractions. This means the writing often comes across as more conversational. 
• Informal tone : Nonacademic writing typically has a more informal tone than academic writing.
• Personal opinions : A writer's personal opinions and feelings are often included in this style of writing.
• Less formal structure : There is usually no strict structure or format to nonacademic writing styles.
• Less emphasis on research : Writers often rely more on personal experience and anecdotes in this style of writing.
• Use of humor and figurative language : Humor and figurative language can make writing content more engaging.
• Less or no citation requirement : Nonacademic writing often doesn't require citations and references.
• Simplicity and brevity : Writing is often simple and brief, as it is designed to be easily understood by a wider, general audience.

Both styles of writing have their own unique strengths and weaknesses, and it is important for writers to understand and use the appropriate style for their specific purpose and audience. While academic writing is essential for scholarly research and analysis, nonacademic writing is essential for communicating information and ideas to a general audience.

Final thoughts

In summary, academic writing is formal, objective, and evidence-based, while nonacademic writing is informal, personal, and emotional. The purpose and audience for each style of writing are also different, with academic writing being written for scholarly audiences and nonacademic writing being written for wider audiences. The key element in choosing a writing style is the intended audience.

Scientific writing is part of academic writing skills and communication skills. These skills develop gradually during your studies through writing, reading, listening, having discussions, giving and receiving feedback as well as through reflecting on your own skills. Currently scientific information may be interpreted and produced in a variety of ways, for example, in written, spoken, printed, audiovisual or digital form.

Academic writing.

Academic writing is communal and conventional by nature: the forms and norms of expression vary between environments. Consequently, studying academic writing is part of learning the rules of the scientific community. These rules are learned little by little by participating in the activities of the community: by writing texts and discussing them with diverse readers and by giving and receiving feedback .

Co-authoring is also useful, since it strengthens feedback and collaboration skills.  In many academic work communities, texts are drawn up in collaboration by several specialists and scientific publications will go through a peer review process in which experts in the field read and comment on manuscripts.

Writing is also about process management . Many genres of academic writing, such as theses, are extensive works the production of which requires self-regulation and life management skills. Therefore, reflecting on your own skills is crucial for the development of writing skills. Writing is about choices and problem-solving, but you do not have to solve problems on your own: students are provided with a large variety of tools to support the development of academic writing and communication skills.

Tips for developing your writing skills

Feedback and assessment

Are you confused by feedback or frustrated about the lack of feedback? The Plotti website features an entry providing tips for better feedback experiences (in Finnish only). 

The Kielijelppi website provides information on how to finalise your text for assessment (in Finnish only).

Discipline-specific practices

Writing guidelines provided by your degree programme provide help in the practices of your discipline. You can also ask for assistance from teachers and supervisors in your degree programme. Select your degree programme and review the more detailed guidelines on academic writing by your faculty or degree programme, if available. You can also learn about practices by reading and analysing publications in your discipline. Many peer-reviewed publications also provide guidelines intended for contributors, which shed light on the writing conventions of the publication.

Seeking scientific information

Academic writing requires reviewing prior research. When seeking existing research-based knowledge, you must be versed in the techniques of scientific information retrieval and know how to critically evaluate information sources. Your research subject and discipline largely determine which sources you should utilise in your work.  

You can start your information seeking by  

• Browsing new literature in your discipline in HELKA (limit the search to new items) or visiting the library at the shelf of the category in which you are interested 
• Performing information searches related to your subject in library databases 
• Picking up interesting information sources from the references in the research literature you have found 

The Instructions for Students website has collated more tips for information retrieval and management .

You can find out more about information sources in various fields in research guides compiled by specialists at Helsinki University Library .

If you wish to study scientific information retrieval independently, you may take part in the Information Seeking and Management for Thesis Writers MOOC .

Citation practices

Citing sources.

Citing sources is a key part of the academic writing process. Source references are meant to express unambiguously and transparently what sources the author has used in their text. References must be made utilising the established citation practices of the field in question. Different disciplines may have their own citation practices on which you will receive guidance from your degree programme.  It is recommended that you acquaint yourself with source citation practices in the early stages of your writing process.  

You can study the use of source citations and drawing up a bibliography, for example, with material provided by the Student’s Digital Skills course or the Kielijelppi referencing guidelines (in Finnish only).

More information on the use of images in academic writing and referring to images is available in the Tips for information retrieval and management .

For guidelines on how to reference AI, see Tips for information retrieval and management .

Reference management software

Once you have studied the citation practices in your discipline, you may start using reference management software. The software helps you to keep your references in order and draw up a bibliography in accordance with a certain style. There are many different reference management programs available, such as EndNote, Zotero and Mendeley.  

Acquaint yourself with reference management programs on the Library website . 

Copyright and plagiarism

Familiarise yourself with the self-study materials on the Kopiraittila website , which will provide you with information on the appropriate consideration of copyright in scientific texts (for example, the use of images and graphs and appropriate citing from the perspective of copyright).

The Finnish Code of Conduct for Research Integrity and Procedures for Handling Alleged Violations of Research Integrity in Finland (Finnish National Board on Research Integrity TENK)

The University of Helsinki also uses the plagiarism detection system Urkund to support teaching and the supervision of academic writing.

Tips for sources: Aid for scientific writing

Websites maintained by language centre support you with scientific writing and interaction.

Kielijelppi  (in Finnish) Kielijelppi is a digital guide for writing and verbal communication, which offers help with different kinds of texts and oral presentations as well as support for communicative situations. (In Finnish) 

Plotti – kaikkea viestinnästä  (In Finnish) Plotti is a blog where you can find articles about writing and interaction especially from the point of view of an university student. Plotti is a good tool for writers and editors. (In Finnish)

Research and Writing at Graduate Level

Any program leading to the Master of Arts fosters the student’s transition into a profession. Students learn how to discuss ideas in a particular discipline as professionals among professionals. To attain this goal, graduate students routinely engage in research and writing where correct documentation of sources signifies much more than the avoidance of plagiarism. Research and writing about scholarly discoveries signal the graduate student’s membership in a professional community.

Thus research papers written for graduate courses will differ from those written for undergraduate courses. The graduate student’s research paper will sustain deeper analysis of a topic at greater length and with narrower focus than the undergraduate paper. Graduate research papers will employ a significant scope of sources that are current, authoritative, and recognized within a particular area of study. Additionally, the graduate research paper demonstrates the student’s ability to identify appropriate topics related to course material and to exercise independence in both research and writing.

Graduate-level papers will also demonstrate the student’s ability to document all sources accurately and to edit carefully for standard American English. Students should refer to  The MLA Handbook for Writers of Research Papers , 8th Edition (ISBN 978-1-60329-262-7), if they have questions about documentation, though some courses may ask students to follow the Chicago Manual of Style or the Publication Manual of the American Psychological Association .

To prepare students for the level of research and writing required in graduate courses, professors incorporate into their classes instruction in bibliography and methodology appropriate to course content. Professors will assist students to access and learn how to access and evaluate scholarly materials. Professors may further provide rubrics or specific requirements about the nature and originality of the research and writing expected in fulfillment of a particular assignment.

Introduction to scientific/technical writing

Scientific/technical writing is an essential part of research. The outcome of a research activity should be shared with others in the form of scientific paper publications; some ideas require a patent to reserve the implementation rights; and almost any research activity requires a funding source, for which a grant proposal is necessary. Therefore, it is crucial to know the differences among writing papers, patents, and grant proposals and how to prepare them in a research environment ( Figure 1 ).

Three major types of scientific/technical writing covered in the three-part series.

The publication of papers is a standard way to share knowledge and transfer methods in scientific communities, thus a pivotal part of any research activity, especially in an academic environment. In industry, where financial profit is a key factor, patents are possibly more favorable.

Types of paper publications

There are different types of paper publications, depending on the content, audience, purpose, length, and scope: original research, review articles, invited articles, conference proceedings, comments/errata, and press releases ( Figure 2 ).

Original research articles may be published in journals or conference proceedings (or preprints in arXiv) and target specific audiences within a field of research. Journal research papers require peer review that typically involves an editor and two reviewers. For conference proceedings, there is usually no direct peer-review process, but the work has to be presented in the corresponding conference to be eligible for publication.

In contrast to original research articles, which are written on special topics within a field of research, review articles normally cover an overview of research and tend to be longer. Review articles do not necessarily reflect on novel data or ideas and could be similar to a book chapter. However, unlike review articles, book chapters or books are usually written when the target field of research is fully established. In a review paper, figures are typically not original and reprinted from other publications, for which a copyright permission from the original publishing journal is required.

Invited articles are written in response to an invitation by a journal editor or a conference organizer in a specific field of research or for a special issue. An invited article could be a review article or original research. Invited articles are normally written by peers or researchers with significant contributions to a field of research.

Other items published include comments or errata. The purpose of a comment on a published article is to bring points of criticism to the attention of the readers as well as the authors of the original article. The comments can be published in the same journal as the original paper. Errata correct mistakes in an article after publication.

Finally, press releases target a more general audience and normally report on a review/overview of recently published research. The author of the press release is not the same as that of the original article. Unlike peer-reviewed research articles, press release articles are usually not citable.

Six major types of paper publications.

Writing structures and styles

Different articles have different structures. A research article typically consists of a title, author list and affiliations, abstract, main body, conclusions, acknowledgments, and references.

A good title should be concise, to the point, and free of abbreviations. Author lists and affiliations include whoever has intellectually contributed to the paper (identifying at least one corresponding author and email address), with the order approved by all of the co-authors. A good abstract should give a full, but short, overview of the work with both qualitative and quantitative data summaries. An abstract should be self-contained, meaning it should not require a referral to a reference or figure. Abstracts are usually written in the present tense and have an active voice.

Unlike letters with no sections within the main body, the main body of research articles normally contains several sections (e.g., introduction, methods and approach, results, and discussions). The introduction should contain a deep literature review of the field as the basis for motivating the current work. The last paragraph of the introduction usually summarizes what to expect from the article. The following sections will demonstrate study methods, results, and discussions/interpretations of the results, including plots, tables, and figures.

Conclusions summarize the findings of the paper and may point out any future directions. The acknowledgment lists all funding support and gratitude toward anyone who helped with the work, not including those listed as co-authors. The reference section lists all references in a format described in the journal submission guidelines. Using reference management software (such as Zotero, Mendeley, BibTex) makes organizing the references less cumbersome. A good scholarly research article should have citations for almost any claims made within the main body, to ensure proper connections to the prior research in the field.

Unlike patents, papers require a deep scientific background and should be straight to the point. While patents include all aspects of the idea, papers typically have space limitations, so should therefore be concise. The data in research articles should speak for itself. The language of a research paper should be clear and simple and not include metaphors or slang.

Where to submit

The submission target depends on several factors: (1) scope of the journal, (2) length of the paper (letters versus regular length articles), (3) access (regular versus open access), and (4) impact factor (IF). The scope of the journal is probably the first thing to consider; you cannot publish a biological paper in a humanity journal. Regarding length, a letter is much shorter and usually does not have section headings. It depends on the discipline, but sometimes letters are more favorable because of the shorter publication time, preparation simplicity, and more readability (takes less time to read, which may also improve the visibility of the paper). In terms of access, you may pay publication charges to receive open access, or some journals charge publication fees upon acceptance. Open access papers could potentially get more visibility than normal publications.

IF is a specific journal parameter indicating the average number of citations per published article over a certain period of time. Paying serious attention to IF could oppose the mission of science itself, as it could mean that you judge a paper only by where it is being published and not by its intrinsic values (also called high IF syndrome).

Submission, peer-review, and decisions

Your article will enter the peer-review process upon submission. If done properly, the peer-review process not only avoids false or inconsistent data from being published (and helps science in this regard), but also improves your paper and removes any potential errors/issues or vague discussion. During submission, some journals may ask you to include/exclude reviewers. If there are researchers who may have a direct conflict with your work, you may list them as excluded reviewers. You may also suggest to include reviewers who have relevant experience.

Serving as a reviewer may help you with your own writing, as it assists in developing critical thinking. However, for the sake of science, try peer-reviewing for lesser-known journals (the high-impact journals already have many reviewers). Decisions on your article could be (1) reject: cannot be accepted to this journal; (2) referral to other journals; submit to another journal; (3) accept: accepted as is; (4) major revisions: not accepted, but could be accepted upon significant improvement (upon approval from reviewers); and (5) minor revision: accept but needs slight revisions (no need to go through a peer review again).

Copyrights and archiving

Most journals obtain copyrights from the authors before submission via a copyright transfer form. Hence, re-publishing the same data and plots in another journal is often forbidden. Also, the language of a paper should have a significant difference from an already published paper to avoid plagiarism. In the case where some content (e.g., figure or table) needs to be re-published in another paper (e.g., for review articles or thesis/dissertations), one can request a copyright permission from the original publishing journal. Also, archiving of one’s published papers in personal profile websites (e.g., Researchgate or LinkedIn) is usually forbidden, unless the paper is published as open access.

Final tips for paper publication

Read, read, read! There is probably no better way of improving writing skills than reading other articles and books.

Make illustrative and self-contained figures that can stand on their own.

Know your audience when selecting a journal. Find out which journals are normally targeted by people in your research community.

Protect yourself from high impact factor (IF) syndrome. Journals with a high IF may have very subjective decision criteria. It is sometimes more important to have your paper published than to spend a couple of years waiting for publication in a high-impact journal.

Serve as a reviewer. Get a sense of how a peer-review process feels in order to establish critical thinking. Before submitting your article, self-review.

Look forward to a constructive peer review. It definitely improves your paper (always good to have a view from different perspective).

Enjoy your publications!

The development of research questions and the subsequent hypotheses are prerequisites to defining the main research purpose and specific objectives of a study. Consequently, these objectives determine the study design and research outcome. The development of research questions is a process based on knowledge of current trends, cutting-edge studies, and technological advances in the research field. Excellent research questions are focused and require a comprehensive literature search and in-depth understanding of the problem being investigated. Initially, research questions may be written as descriptive questions which could be developed into inferential questions. These questions must be specific and concise to provide a clear foundation for developing hypotheses. Hypotheses are more formal predictions about the research outcomes. These specify the possible results that may or may not be expected regarding the relationship between groups. Thus, research questions and hypotheses clarify the main purpose and specific objectives of the study, which in turn dictate the design of the study, its direction, and outcome. Studies developed from good research questions and hypotheses will have trustworthy outcomes with wide-ranging social and health implications.

INTRODUCTION

Scientific research is usually initiated by posing evidenced-based research questions which are then explicitly restated as hypotheses. 1 , 2 The hypotheses provide directions to guide the study, solutions, explanations, and expected results. 3 , 4 Both research questions and hypotheses are essentially formulated based on conventional theories and real-world processes, which allow the inception of novel studies and the ethical testing of ideas. 5 , 6

It is crucial to have knowledge of both quantitative and qualitative research 2 as both types of research involve writing research questions and hypotheses. 7 However, these crucial elements of research are sometimes overlooked; if not overlooked, then framed without the forethought and meticulous attention it needs. Planning and careful consideration are needed when developing quantitative or qualitative research, particularly when conceptualizing research questions and hypotheses. 4

There is a continuing need to support researchers in the creation of innovative research questions and hypotheses, as well as for journal articles that carefully review these elements. 1 When research questions and hypotheses are not carefully thought of, unethical studies and poor outcomes usually ensue. Carefully formulated research questions and hypotheses define well-founded objectives, which in turn determine the appropriate design, course, and outcome of the study. This article then aims to discuss in detail the various aspects of crafting research questions and hypotheses, with the goal of guiding researchers as they develop their own. Examples from the authors and peer-reviewed scientific articles in the healthcare field are provided to illustrate key points.

DEFINITIONS AND RELATIONSHIP OF RESEARCH QUESTIONS AND HYPOTHESES

A research question is what a study aims to answer after data analysis and interpretation. The answer is written in length in the discussion section of the paper. Thus, the research question gives a preview of the different parts and variables of the study meant to address the problem posed in the research question. 1 An excellent research question clarifies the research writing while facilitating understanding of the research topic, objective, scope, and limitations of the study. 5

On the other hand, a research hypothesis is an educated statement of an expected outcome. This statement is based on background research and current knowledge. 8 , 9 The research hypothesis makes a specific prediction about a new phenomenon 10 or a formal statement on the expected relationship between an independent variable and a dependent variable. 3 , 11 It provides a tentative answer to the research question to be tested or explored. 4

Hypotheses employ reasoning to predict a theory-based outcome. 10 These can also be developed from theories by focusing on components of theories that have not yet been observed. 10 The validity of hypotheses is often based on the testability of the prediction made in a reproducible experiment. 8

Conversely, hypotheses can also be rephrased as research questions. Several hypotheses based on existing theories and knowledge may be needed to answer a research question. Developing ethical research questions and hypotheses creates a research design that has logical relationships among variables. These relationships serve as a solid foundation for the conduct of the study. 4 , 11 Haphazardly constructed research questions can result in poorly formulated hypotheses and improper study designs, leading to unreliable results. Thus, the formulations of relevant research questions and verifiable hypotheses are crucial when beginning research. 12

CHARACTERISTICS OF GOOD RESEARCH QUESTIONS AND HYPOTHESES

Excellent research questions are specific and focused. These integrate collective data and observations to confirm or refute the subsequent hypotheses. Well-constructed hypotheses are based on previous reports and verify the research context. These are realistic, in-depth, sufficiently complex, and reproducible. More importantly, these hypotheses can be addressed and tested. 13

There are several characteristics of well-developed hypotheses. Good hypotheses are 1) empirically testable 7 , 10 , 11 , 13 ; 2) backed by preliminary evidence 9 ; 3) testable by ethical research 7 , 9 ; 4) based on original ideas 9 ; 5) have evidenced-based logical reasoning 10 ; and 6) can be predicted. 11 Good hypotheses can infer ethical and positive implications, indicating the presence of a relationship or effect relevant to the research theme. 7 , 11 These are initially developed from a general theory and branch into specific hypotheses by deductive reasoning. In the absence of a theory to base the hypotheses, inductive reasoning based on specific observations or findings form more general hypotheses. 10

TYPES OF RESEARCH QUESTIONS AND HYPOTHESES

Research questions and hypotheses are developed according to the type of research, which can be broadly classified into quantitative and qualitative research. We provide a summary of the types of research questions and hypotheses under quantitative and qualitative research categories in Table 1 .

Research questions in quantitative research

In quantitative research, research questions inquire about the relationships among variables being investigated and are usually framed at the start of the study. These are precise and typically linked to the subject population, dependent and independent variables, and research design. 1 Research questions may also attempt to describe the behavior of a population in relation to one or more variables, or describe the characteristics of variables to be measured ( descriptive research questions ). 1 , 5 , 14 These questions may also aim to discover differences between groups within the context of an outcome variable ( comparative research questions ), 1 , 5 , 14 or elucidate trends and interactions among variables ( relationship research questions ). 1 , 5 We provide examples of descriptive, comparative, and relationship research questions in quantitative research in Table 2 .

Hypotheses in quantitative research

In quantitative research, hypotheses predict the expected relationships among variables. 15 Relationships among variables that can be predicted include 1) between a single dependent variable and a single independent variable ( simple hypothesis ) or 2) between two or more independent and dependent variables ( complex hypothesis ). 4 , 11 Hypotheses may also specify the expected direction to be followed and imply an intellectual commitment to a particular outcome ( directional hypothesis ) 4 . On the other hand, hypotheses may not predict the exact direction and are used in the absence of a theory, or when findings contradict previous studies ( non-directional hypothesis ). 4 In addition, hypotheses can 1) define interdependency between variables ( associative hypothesis ), 4 2) propose an effect on the dependent variable from manipulation of the independent variable ( causal hypothesis ), 4 3) state a negative relationship between two variables ( null hypothesis ), 4 , 11 , 15 4) replace the working hypothesis if rejected ( alternative hypothesis ), 15 explain the relationship of phenomena to possibly generate a theory ( working hypothesis ), 11 5) involve quantifiable variables that can be tested statistically ( statistical hypothesis ), 11 6) or express a relationship whose interlinks can be verified logically ( logical hypothesis ). 11 We provide examples of simple, complex, directional, non-directional, associative, causal, null, alternative, working, statistical, and logical hypotheses in quantitative research, as well as the definition of quantitative hypothesis-testing research in Table 3 .

Research questions in qualitative research

Unlike research questions in quantitative research, research questions in qualitative research are usually continuously reviewed and reformulated. The central question and associated subquestions are stated more than the hypotheses. 15 The central question broadly explores a complex set of factors surrounding the central phenomenon, aiming to present the varied perspectives of participants. 15

There are varied goals for which qualitative research questions are developed. These questions can function in several ways, such as to 1) identify and describe existing conditions ( contextual research question s); 2) describe a phenomenon ( descriptive research questions ); 3) assess the effectiveness of existing methods, protocols, theories, or procedures ( evaluation research questions ); 4) examine a phenomenon or analyze the reasons or relationships between subjects or phenomena ( explanatory research questions ); or 5) focus on unknown aspects of a particular topic ( exploratory research questions ). 5 In addition, some qualitative research questions provide new ideas for the development of theories and actions ( generative research questions ) or advance specific ideologies of a position ( ideological research questions ). 1 Other qualitative research questions may build on a body of existing literature and become working guidelines ( ethnographic research questions ). Research questions may also be broadly stated without specific reference to the existing literature or a typology of questions ( phenomenological research questions ), may be directed towards generating a theory of some process ( grounded theory questions ), or may address a description of the case and the emerging themes ( qualitative case study questions ). 15 We provide examples of contextual, descriptive, evaluation, explanatory, exploratory, generative, ideological, ethnographic, phenomenological, grounded theory, and qualitative case study research questions in qualitative research in Table 4 , and the definition of qualitative hypothesis-generating research in Table 5 .

Qualitative studies usually pose at least one central research question and several subquestions starting with How or What . These research questions use exploratory verbs such as explore or describe . These also focus on one central phenomenon of interest, and may mention the participants and research site. 15

Hypotheses in qualitative research

Hypotheses in qualitative research are stated in the form of a clear statement concerning the problem to be investigated. Unlike in quantitative research where hypotheses are usually developed to be tested, qualitative research can lead to both hypothesis-testing and hypothesis-generating outcomes. 2 When studies require both quantitative and qualitative research questions, this suggests an integrative process between both research methods wherein a single mixed-methods research question can be developed. 1

FRAMEWORKS FOR DEVELOPING RESEARCH QUESTIONS AND HYPOTHESES

Research questions followed by hypotheses should be developed before the start of the study. 1 , 12 , 14 It is crucial to develop feasible research questions on a topic that is interesting to both the researcher and the scientific community. This can be achieved by a meticulous review of previous and current studies to establish a novel topic. Specific areas are subsequently focused on to generate ethical research questions. The relevance of the research questions is evaluated in terms of clarity of the resulting data, specificity of the methodology, objectivity of the outcome, depth of the research, and impact of the study. 1 , 5 These aspects constitute the FINER criteria (i.e., Feasible, Interesting, Novel, Ethical, and Relevant). 1 Clarity and effectiveness are achieved if research questions meet the FINER criteria. In addition to the FINER criteria, Ratan et al. described focus, complexity, novelty, feasibility, and measurability for evaluating the effectiveness of research questions. 14

The PICOT and PEO frameworks are also used when developing research questions. 1 The following elements are addressed in these frameworks, PICOT: P-population/patients/problem, I-intervention or indicator being studied, C-comparison group, O-outcome of interest, and T-timeframe of the study; PEO: P-population being studied, E-exposure to preexisting conditions, and O-outcome of interest. 1 Research questions are also considered good if these meet the “FINERMAPS” framework: Feasible, Interesting, Novel, Ethical, Relevant, Manageable, Appropriate, Potential value/publishable, and Systematic. 14

As we indicated earlier, research questions and hypotheses that are not carefully formulated result in unethical studies or poor outcomes. To illustrate this, we provide some examples of ambiguous research question and hypotheses that result in unclear and weak research objectives in quantitative research ( Table 6 ) 16 and qualitative research ( Table 7 ) 17 , and how to transform these ambiguous research question(s) and hypothesis(es) into clear and good statements.

CONSTRUCTING RESEARCH QUESTIONS AND HYPOTHESES

To construct effective research questions and hypotheses, it is very important to 1) clarify the background and 2) identify the research problem at the outset of the research, within a specific timeframe. 9 Then, 3) review or conduct preliminary research to collect all available knowledge about the possible research questions by studying theories and previous studies. 18 Afterwards, 4) construct research questions to investigate the research problem. Identify variables to be accessed from the research questions 4 and make operational definitions of constructs from the research problem and questions. Thereafter, 5) construct specific deductive or inductive predictions in the form of hypotheses. 4 Finally, 6) state the study aims . This general flow for constructing effective research questions and hypotheses prior to conducting research is shown in Fig. 1 .

Research questions are used more frequently in qualitative research than objectives or hypotheses. 3 These questions seek to discover, understand, explore or describe experiences by asking “What” or “How.” The questions are open-ended to elicit a description rather than to relate variables or compare groups. The questions are continually reviewed, reformulated, and changed during the qualitative study. 3 Research questions are also used more frequently in survey projects than hypotheses in experiments in quantitative research to compare variables and their relationships.

Hypotheses are constructed based on the variables identified and as an if-then statement, following the template, ‘If a specific action is taken, then a certain outcome is expected.’ At this stage, some ideas regarding expectations from the research to be conducted must be drawn. 18 Then, the variables to be manipulated (independent) and influenced (dependent) are defined. 4 Thereafter, the hypothesis is stated and refined, and reproducible data tailored to the hypothesis are identified, collected, and analyzed. 4 The hypotheses must be testable and specific, 18 and should describe the variables and their relationships, the specific group being studied, and the predicted research outcome. 18 Hypotheses construction involves a testable proposition to be deduced from theory, and independent and dependent variables to be separated and measured separately. 3 Therefore, good hypotheses must be based on good research questions constructed at the start of a study or trial. 12

In summary, research questions are constructed after establishing the background of the study. Hypotheses are then developed based on the research questions. Thus, it is crucial to have excellent research questions to generate superior hypotheses. In turn, these would determine the research objectives and the design of the study, and ultimately, the outcome of the research. 12 Algorithms for building research questions and hypotheses are shown in Fig. 2 for quantitative research and in Fig. 3 for qualitative research.

EXAMPLES OF RESEARCH QUESTIONS FROM PUBLISHED ARTICLES

• EXAMPLE 1. Descriptive research question (quantitative research)
• - Presents research variables to be assessed (distinct phenotypes and subphenotypes)
• “BACKGROUND: Since COVID-19 was identified, its clinical and biological heterogeneity has been recognized. Identifying COVID-19 phenotypes might help guide basic, clinical, and translational research efforts.
• RESEARCH QUESTION: Does the clinical spectrum of patients with COVID-19 contain distinct phenotypes and subphenotypes? ” 19
• EXAMPLE 2. Relationship research question (quantitative research)
• - Shows interactions between dependent variable (static postural control) and independent variable (peripheral visual field loss)
• “Background: Integration of visual, vestibular, and proprioceptive sensations contributes to postural control. People with peripheral visual field loss have serious postural instability. However, the directional specificity of postural stability and sensory reweighting caused by gradual peripheral visual field loss remain unclear.
• Research question: What are the effects of peripheral visual field loss on static postural control ?” 20
• EXAMPLE 3. Comparative research question (quantitative research)
• - Clarifies the difference among groups with an outcome variable (patients enrolled in COMPERA with moderate PH or severe PH in COPD) and another group without the outcome variable (patients with idiopathic pulmonary arterial hypertension (IPAH))
• “BACKGROUND: Pulmonary hypertension (PH) in COPD is a poorly investigated clinical condition.
• RESEARCH QUESTION: Which factors determine the outcome of PH in COPD?
• STUDY DESIGN AND METHODS: We analyzed the characteristics and outcome of patients enrolled in the Comparative, Prospective Registry of Newly Initiated Therapies for Pulmonary Hypertension (COMPERA) with moderate or severe PH in COPD as defined during the 6th PH World Symposium who received medical therapy for PH and compared them with patients with idiopathic pulmonary arterial hypertension (IPAH) .” 21
• EXAMPLE 4. Exploratory research question (qualitative research)
• - Explores areas that have not been fully investigated (perspectives of families and children who receive care in clinic-based child obesity treatment) to have a deeper understanding of the research problem
• “Problem: Interventions for children with obesity lead to only modest improvements in BMI and long-term outcomes, and data are limited on the perspectives of families of children with obesity in clinic-based treatment. This scoping review seeks to answer the question: What is known about the perspectives of families and children who receive care in clinic-based child obesity treatment? This review aims to explore the scope of perspectives reported by families of children with obesity who have received individualized outpatient clinic-based obesity treatment.” 22
• EXAMPLE 5. Relationship research question (quantitative research)
• - Defines interactions between dependent variable (use of ankle strategies) and independent variable (changes in muscle tone)
• “Background: To maintain an upright standing posture against external disturbances, the human body mainly employs two types of postural control strategies: “ankle strategy” and “hip strategy.” While it has been reported that the magnitude of the disturbance alters the use of postural control strategies, it has not been elucidated how the level of muscle tone, one of the crucial parameters of bodily function, determines the use of each strategy. We have previously confirmed using forward dynamics simulations of human musculoskeletal models that an increased muscle tone promotes the use of ankle strategies. The objective of the present study was to experimentally evaluate a hypothesis: an increased muscle tone promotes the use of ankle strategies. Research question: Do changes in the muscle tone affect the use of ankle strategies ?” 23

EXAMPLES OF HYPOTHESES IN PUBLISHED ARTICLES

• EXAMPLE 1. Working hypothesis (quantitative research)
• - A hypothesis that is initially accepted for further research to produce a feasible theory
• “As fever may have benefit in shortening the duration of viral illness, it is plausible to hypothesize that the antipyretic efficacy of ibuprofen may be hindering the benefits of a fever response when taken during the early stages of COVID-19 illness .” 24
• “In conclusion, it is plausible to hypothesize that the antipyretic efficacy of ibuprofen may be hindering the benefits of a fever response . The difference in perceived safety of these agents in COVID-19 illness could be related to the more potent efficacy to reduce fever with ibuprofen compared to acetaminophen. Compelling data on the benefit of fever warrant further research and review to determine when to treat or withhold ibuprofen for early stage fever for COVID-19 and other related viral illnesses .” 24
• EXAMPLE 2. Exploratory hypothesis (qualitative research)
• - Explores particular areas deeper to clarify subjective experience and develop a formal hypothesis potentially testable in a future quantitative approach
• “We hypothesized that when thinking about a past experience of help-seeking, a self distancing prompt would cause increased help-seeking intentions and more favorable help-seeking outcome expectations .” 25
• “Conclusion
• Although a priori hypotheses were not supported, further research is warranted as results indicate the potential for using self-distancing approaches to increasing help-seeking among some people with depressive symptomatology.” 25
• EXAMPLE 3. Hypothesis-generating research to establish a framework for hypothesis testing (qualitative research)
• “We hypothesize that compassionate care is beneficial for patients (better outcomes), healthcare systems and payers (lower costs), and healthcare providers (lower burnout). ” 26
• Compassionomics is the branch of knowledge and scientific study of the effects of compassionate healthcare. Our main hypotheses are that compassionate healthcare is beneficial for (1) patients, by improving clinical outcomes, (2) healthcare systems and payers, by supporting financial sustainability, and (3) HCPs, by lowering burnout and promoting resilience and well-being. The purpose of this paper is to establish a scientific framework for testing the hypotheses above . If these hypotheses are confirmed through rigorous research, compassionomics will belong in the science of evidence-based medicine, with major implications for all healthcare domains.” 26
• EXAMPLE 4. Statistical hypothesis (quantitative research)
• - An assumption is made about the relationship among several population characteristics ( gender differences in sociodemographic and clinical characteristics of adults with ADHD ). Validity is tested by statistical experiment or analysis ( chi-square test, Students t-test, and logistic regression analysis)
• “Our research investigated gender differences in sociodemographic and clinical characteristics of adults with ADHD in a Japanese clinical sample. Due to unique Japanese cultural ideals and expectations of women's behavior that are in opposition to ADHD symptoms, we hypothesized that women with ADHD experience more difficulties and present more dysfunctions than men . We tested the following hypotheses: first, women with ADHD have more comorbidities than men with ADHD; second, women with ADHD experience more social hardships than men, such as having less full-time employment and being more likely to be divorced.” 27
• “Statistical Analysis
• ( text omitted ) Between-gender comparisons were made using the chi-squared test for categorical variables and Students t-test for continuous variables…( text omitted ). A logistic regression analysis was performed for employment status, marital status, and comorbidity to evaluate the independent effects of gender on these dependent variables.” 27

EXAMPLES OF HYPOTHESIS AS WRITTEN IN PUBLISHED ARTICLES IN RELATION TO OTHER PARTS

• EXAMPLE 1. Background, hypotheses, and aims are provided
• “Pregnant women need skilled care during pregnancy and childbirth, but that skilled care is often delayed in some countries …( text omitted ). The focused antenatal care (FANC) model of WHO recommends that nurses provide information or counseling to all pregnant women …( text omitted ). Job aids are visual support materials that provide the right kind of information using graphics and words in a simple and yet effective manner. When nurses are not highly trained or have many work details to attend to, these job aids can serve as a content reminder for the nurses and can be used for educating their patients (Jennings, Yebadokpo, Affo, & Agbogbe, 2010) ( text omitted ). Importantly, additional evidence is needed to confirm how job aids can further improve the quality of ANC counseling by health workers in maternal care …( text omitted )” 28
• “ This has led us to hypothesize that the quality of ANC counseling would be better if supported by job aids. Consequently, a better quality of ANC counseling is expected to produce higher levels of awareness concerning the danger signs of pregnancy and a more favorable impression of the caring behavior of nurses .” 28
• “This study aimed to examine the differences in the responses of pregnant women to a job aid-supported intervention during ANC visit in terms of 1) their understanding of the danger signs of pregnancy and 2) their impression of the caring behaviors of nurses to pregnant women in rural Tanzania.” 28
• EXAMPLE 2. Background, hypotheses, and aims are provided
• “We conducted a two-arm randomized controlled trial (RCT) to evaluate and compare changes in salivary cortisol and oxytocin levels of first-time pregnant women between experimental and control groups. The women in the experimental group touched and held an infant for 30 min (experimental intervention protocol), whereas those in the control group watched a DVD movie of an infant (control intervention protocol). The primary outcome was salivary cortisol level and the secondary outcome was salivary oxytocin level.” 29
• “ We hypothesize that at 30 min after touching and holding an infant, the salivary cortisol level will significantly decrease and the salivary oxytocin level will increase in the experimental group compared with the control group .” 29
• EXAMPLE 3. Background, aim, and hypothesis are provided
• “In countries where the maternal mortality ratio remains high, antenatal education to increase Birth Preparedness and Complication Readiness (BPCR) is considered one of the top priorities [1]. BPCR includes birth plans during the antenatal period, such as the birthplace, birth attendant, transportation, health facility for complications, expenses, and birth materials, as well as family coordination to achieve such birth plans. In Tanzania, although increasing, only about half of all pregnant women attend an antenatal clinic more than four times [4]. Moreover, the information provided during antenatal care (ANC) is insufficient. In the resource-poor settings, antenatal group education is a potential approach because of the limited time for individual counseling at antenatal clinics.” 30
• “This study aimed to evaluate an antenatal group education program among pregnant women and their families with respect to birth-preparedness and maternal and infant outcomes in rural villages of Tanzania.” 30
• “ The study hypothesis was if Tanzanian pregnant women and their families received a family-oriented antenatal group education, they would (1) have a higher level of BPCR, (2) attend antenatal clinic four or more times, (3) give birth in a health facility, (4) have less complications of women at birth, and (5) have less complications and deaths of infants than those who did not receive the education .” 30

Research questions and hypotheses are crucial components to any type of research, whether quantitative or qualitative. These questions should be developed at the very beginning of the study. Excellent research questions lead to superior hypotheses, which, like a compass, set the direction of research, and can often determine the successful conduct of the study. Many research studies have floundered because the development of research questions and subsequent hypotheses was not given the thought and meticulous attention needed. The development of research questions and hypotheses is an iterative process based on extensive knowledge of the literature and insightful grasp of the knowledge gap. Focused, concise, and specific research questions provide a strong foundation for constructing hypotheses which serve as formal predictions about the research outcomes. Research questions and hypotheses are crucial elements of research that should not be overlooked. They should be carefully thought of and constructed when planning research. This avoids unethical studies and poor outcomes by defining well-founded objectives that determine the design, course, and outcome of the study.

Writing a Paper: Comparing & Contrasting

A compare and contrast paper discusses the similarities and differences between two or more topics. The paper should contain an introduction with a thesis statement, a body where the comparisons and contrasts are discussed, and a conclusion.

Address Both Similarities and Differences

Because this is a compare and contrast paper, both the similarities and differences should be discussed. This will require analysis on your part, as some topics will appear to be quite similar, and you will have to work to find the differing elements.

Make Sure You Have a Clear Thesis Statement

Just like any other essay, a compare and contrast essay needs a thesis statement. The thesis statement should not only tell your reader what you will do, but it should also address the purpose and importance of comparing and contrasting the material.

Use Clear Transitions

Transitions are important in compare and contrast essays, where you will be moving frequently between different topics or perspectives.

• Examples of transitions and phrases for comparisons: as well, similar to, consistent with, likewise, too
• Examples of transitions and phrases for contrasts: on the other hand, however, although, differs, conversely, rather than.

For more information, check out our transitions page.

Structure Your Paper

Consider how you will present the information. You could present all of the similarities first and then present all of the differences. Or you could go point by point and show the similarity and difference of one point, then the similarity and difference for another point, and so on.

Include Analysis

It is tempting to just provide summary for this type of paper, but analysis will show the importance of the comparisons and contrasts. For instance, if you are comparing two articles on the topic of the nursing shortage, help us understand what this will achieve. Did you find consensus between the articles that will support a certain action step for people in the field? Did you find discrepancies between the two that point to the need for further investigation?

Make Analogous Comparisons

When drawing comparisons or making contrasts, be sure you are dealing with similar aspects of each item. To use an old cliché, are you comparing apples to apples?

• Example of poor comparisons: Kubista studied the effects of a later start time on high school students, but Cook used a mixed methods approach. (This example does not compare similar items. It is not a clear contrast because the sentence does not discuss the same element of the articles. It is like comparing apples to oranges.)
• Example of analogous comparisons: Cook used a mixed methods approach, whereas Kubista used only quantitative methods. (Here, methods are clearly being compared, allowing the reader to understand the distinction.

Difference Between Research Paper and Essay

October 23, 2023

Description: Comparison of research papers vs. essays, along with the explanation of the differences and similarities between the two types of academic papers. A short guide to understanding essay writing and research writing with definitions of the terms “essay” and “research paper”.

How Does Research Paper Differ From Essay?

Students often have to deal with two different types of academic writing assignments: an essay and a research paper. Writing essays and research papers can be difficult and confusing due to the many similarities they have. To avoid confusion when writing either of these, it’s important to learn their differences. Understanding the differences between an essay and a research paper is also a great way to improve your academic writing skills. This article aims to help you understand the key differences between essay and research paper writing assignments when you come across them. We’ll study their features, look for relevant academic terminology, and learn what differentiates them. To get to the bottom of the difference between these two academic assignments, we should first define essay vs research paper.

What is an Essay?

An essay is a short piece of writing that aims to express personal views on a particular topic. It should have at least three pieces of evidence to back up the argument. Essays are typically shorter in length and less complex than research writing. At the same time, essay writing has its own specifics, so using expert proofreading services is a good idea if you aren’t confident in your skills. It’s likely that you’ll write your first essay and research paper when in high school or college. Then arises the question, “Who will write my paper for me ?” A good essay should always have a creative component, so having good writing skills is a must. Essays often aren’t as scientific as research papers, yet they nevertheless need a clear structure. The basic essay writing guidelines recommend following a five-paragraph structure with an introduction, a body, and a conclusion.

What is a Research Paper?

A research paper is the in-depth study of a chosen scientific topic that aims to generate new scientific findings based on previous studies and experiments. It isn’t enough for students to just state the facts or give their opinion on this topic. Your professor will evaluate your ability to think critically, choose trustworthy sources, and have a solid theoretical grounding in the topic of your research. Writing a research paper takes originality, knowledge, and subject matter expertise. Compared to traditional essay writing, research work has a different objective and structure. Research papers use data from primary sources like books on the topic, academic papers, interviews, web sources, and journals. The basic research writing guidelines recommend following this pattern: introduction, methods, results, discussion, and conclusions/recommendations. Research papers may also include acknowledgments, a brief biography of the author for some Master’s or Ph.D. works, references, endnotes, footnotes, and so on.

Key Differences Between Essay and Research Paper

The biggest difference between a research paper and an essay is that a research paper must have a strict methodology and set of study objectives. A research paper should outline a problem and the approaches that can be used to solve it effectively. Meanwhile, an essay can present a personal opinion without any references. Now let us go over other key differences between an essay and a research paper. The following comparison table outlines the key differences between essays and research papers:

Similarities Differences Between Essay and Research Paper

It makes sense that you could find it challenging to tell the difference between an essay and a research paper since there’re so many similarities between the two types of academic papers. That’s why it’s important to learn about the similarities of the two as well.

• Research: Basic research is still necessary in both. Even though you don’t need to do in-depth study for an essay, you still need to at least fact-check your information. However, for a research paper, you’ll need to cite more sources to demonstrate that you’re doing more than simply skimming the topic.
• Structure: The research paper has multiple paragraphs, much like an essay. Although the structure is a little different, the material presented in each paragraph should be in an easy-to-follow format to save the reader’s time from having to wade through irrelevant data and concepts. There should be an introduction, body paragraphs, and a conclusion in both types of papers. When you want to conduct research, there’re some differences, but there’re also a few similarities because you need to present the topic properly.
• Thesis statement: Both types of papers should have a thesis statement that presents an opinion, an argument, or a hypothesis. Even though it isn’t always required for an essay, adding a thesis statement will make your essay sound even more scientific.
• Format and Style: Your professor might recommend a specific format for your paper depending on the topic matter and the class itself. The liberal arts and humanities normally utilize the MLA and Chicago/Turabian formats, while the social sciences typically use the APA format. Both research papers and essays must follow specific formatting guidelines for headers, footers, in-text citations, reference pages, and other elements. These forms guarantee consistency and point readers to the relevant sources.

Research papers and essays are two different types of writing. We can draw the conclusion that the key differences between essays and research papers are those relating to purpose, structure, and format. Even though these two types of papers have many things in common, essays and research papers are written for different purposes. The requirements for a research paper are stricter because it must follow the right structure, format, and methodology. However, an essay is more forgiving because it has a descriptive narrative that allows the author to express their own opinions.

He holds a BSc in Psychology and an MA in Archaeology but found a lasting passion in content writing and marketing. When he's not coaching writers and smoothing workflows, he can usually be found cycling the shores of the French and Italian rivieras.

While many people use these terms interchangeably, blogs and articles are not the same. Understanding the role each has to play in your marketing strategy will help you deliver better content, improve your SEO, and reach more potential customers to drive conversion.

Why business owners and writers get confused

If you’re unsure how blog posts and articles differ, you’re not alone. In fact, misunderstanding the difference has led many companies to blur the lines, making it difficult to untangle the mess.

Part of this is financially motivated: blog posts are seen as less time-consuming to write and thus less costly. As a result, they are overemphasized in marketing strategies, and content which ought to be written as an article is often briefed as a blog.

This undercuts the broader appeal typical of blogs while watering down the authority of articles that appear on them.

What is a blog?

One way to approach this question is through etymology: where does the word come from? As it turns out, blog is a portmanteau, a new word formed from two older ones: web and log.

This is a useful way to think about your blog: as a kind of log or journal for your business. It’s a personal expression, a collection of anecdotes and updates that help readers connect with your business without drowning them in technical details.

In one word, a blog is narrative : it allows a business to tell its story in a relatable way.

What is an article?

An article is a more formal piece of writing. It is informational and focuses on providing evidence for some claim that’s been made—by your product, for example.

{{orderbox}}

An article should be well-researched and follow a logical, rather than narrative, structure. Articles often feature what’s called deductive reasoning : they begin with a set of premises and end with a reasoned conclusion. The goal is to provide your audience with hard evidence to support your points.

6 key differences between blogs and articles

Whether you’re writing your own content or purchasing articles from a writer, it’s important to understand the differences between blogs and articles.

1. Point of view

A blog post is often written in the first person using I or we . This fits into the narrative structure of the blog: you’re having a conversation with your readers, describing an episode in the life of your brand.

An article is almost always written in the third person, although scientific articles may use the first-person plural (we). This emphasizes the author’s objectivity as they present facts and reasoned arguments.

2. Voice or tone

In a nutshell, blog posts tend to be informal, casual, and conversational, whereas articles tend to be formal, professional, and discursive.

Your company’s blog is a way to build a relationship with your audience, helping them to understand the who behind the what while demonstrating your brand’s personality, goals, and interests.

Articles, on the other hand, are written for a technical audience, using a neutral and passive tone of voice to remove the author from consideration.

3. Where it's published

Blogs have two objectives: to bring new customers to your website by appearing in search engine results, and to reinforce your relationship with existing customers. Both of these goals are served by publishing content on a company’s website, which is where you’ll find most blogs.

{{publisher}}

Articles may be published on your website, providing information and evidence, although they will tend to be scattered throughout the site, rather than in a single feed. They may also appear in external publications: newspapers, magazines, and periodicals.

4. The length or word count

It’s generally accepted that blog posts are shorter than articles, although the correct length for each is a hotly debated SEO topic.

In general, blog posts start at 300 words and go up to—but rarely beyond—2000 words.

A complete and well-researched article with a reasoned argument and all the necessary evidence can reach 5000 words or more. This is one good reason why articles have no place on a blog: no casual reader is interested in sifting through that much information.

5. Research

As opinion or narrative pieces, blog posts have less stringent research standards than articles. Consider, for example, a blog post entitled 10 unusual tips for working comfortably from home, versus an article, How crisis and quarantine have reshaped global work trends .

Both pieces deal with adaptation to new professional circumstances, but one would clearly require more research and a structured argument. The blog post may provide a few anecdotal statistics; the article, on the other hand, is making a claim and will need plenty of research to back it up.

6. Reader engagement

Blogs are made to be discussed and shared. Their short, punchy, subjective nature lends itself to social media shares, and readers are often encouraged to leave questions and comments.

Articles are rarely discussed except in academic and technical circles. If the author has done their job and the research and reasoning are sound, only experts will have the knowledge and motivation to pick them apart.

What writers should know

Hopefully you now have a better idea of what type of content should grace your blog and what type should be reserved for articles.

If you’re writing your own content, though, striking the right balance isn’t always easy; and if you’ve hired unskilled writers, you may find they don’t properly understand the difference, either.

Why writing by hand beats typing for thinking and learning

Jonathan Lambert

If you're like many digitally savvy Americans, it has likely been a while since you've spent much time writing by hand.

The laborious process of tracing out our thoughts, letter by letter, on the page is becoming a relic of the past in our screen-dominated world, where text messages and thumb-typed grocery lists have replaced handwritten letters and sticky notes. Electronic keyboards offer obvious efficiency benefits that have undoubtedly boosted our productivity — imagine having to write all your emails longhand.

To keep up, many schools are introducing computers as early as preschool, meaning some kids may learn the basics of typing before writing by hand.

But giving up this slower, more tactile way of expressing ourselves may come at a significant cost, according to a growing body of research that's uncovering the surprising cognitive benefits of taking pen to paper, or even stylus to iPad — for both children and adults.

Is this some kind of joke? A school facing shortages starts teaching standup comedy

In kids, studies show that tracing out ABCs, as opposed to typing them, leads to better and longer-lasting recognition and understanding of letters. Writing by hand also improves memory and recall of words, laying down the foundations of literacy and learning. In adults, taking notes by hand during a lecture, instead of typing, can lead to better conceptual understanding of material.

"There's actually some very important things going on during the embodied experience of writing by hand," says Ramesh Balasubramaniam , a neuroscientist at the University of California, Merced. "It has important cognitive benefits."

While those benefits have long been recognized by some (for instance, many authors, including Jennifer Egan and Neil Gaiman , draft their stories by hand to stoke creativity), scientists have only recently started investigating why writing by hand has these effects.

A slew of recent brain imaging research suggests handwriting's power stems from the relative complexity of the process and how it forces different brain systems to work together to reproduce the shapes of letters in our heads onto the page.

Your brain on handwriting

Both handwriting and typing involve moving our hands and fingers to create words on a page. But handwriting, it turns out, requires a lot more fine-tuned coordination between the motor and visual systems. This seems to more deeply engage the brain in ways that support learning.

Shots - Health News

Feeling artsy here's how making art helps your brain.

"Handwriting is probably among the most complex motor skills that the brain is capable of," says Marieke Longcamp , a cognitive neuroscientist at Aix-Marseille Université.

Gripping a pen nimbly enough to write is a complicated task, as it requires your brain to continuously monitor the pressure that each finger exerts on the pen. Then, your motor system has to delicately modify that pressure to re-create each letter of the words in your head on the page.

"Your fingers have to each do something different to produce a recognizable letter," says Sophia Vinci-Booher , an educational neuroscientist at Vanderbilt University. Adding to the complexity, your visual system must continuously process that letter as it's formed. With each stroke, your brain compares the unfolding script with mental models of the letters and words, making adjustments to fingers in real time to create the letters' shapes, says Vinci-Booher.

That's not true for typing.

To type "tap" your fingers don't have to trace out the form of the letters — they just make three relatively simple and uniform movements. In comparison, it takes a lot more brainpower, as well as cross-talk between brain areas, to write than type.

Recent brain imaging studies bolster this idea. A study published in January found that when students write by hand, brain areas involved in motor and visual information processing " sync up " with areas crucial to memory formation, firing at frequencies associated with learning.

"We don't see that [synchronized activity] in typewriting at all," says Audrey van der Meer , a psychologist and study co-author at the Norwegian University of Science and Technology. She suggests that writing by hand is a neurobiologically richer process and that this richness may confer some cognitive benefits.

Other experts agree. "There seems to be something fundamental about engaging your body to produce these shapes," says Robert Wiley , a cognitive psychologist at the University of North Carolina, Greensboro. "It lets you make associations between your body and what you're seeing and hearing," he says, which might give the mind more footholds for accessing a given concept or idea.

Those extra footholds are especially important for learning in kids, but they may give adults a leg up too. Wiley and others worry that ditching handwriting for typing could have serious consequences for how we all learn and think.

What might be lost as handwriting wanes

The clearest consequence of screens and keyboards replacing pen and paper might be on kids' ability to learn the building blocks of literacy — letters.

"Letter recognition in early childhood is actually one of the best predictors of later reading and math attainment," says Vinci-Booher. Her work suggests the process of learning to write letters by hand is crucial for learning to read them.

"When kids write letters, they're just messy," she says. As kids practice writing "A," each iteration is different, and that variability helps solidify their conceptual understanding of the letter.

Research suggests kids learn to recognize letters better when seeing variable handwritten examples, compared with uniform typed examples.

This helps develop areas of the brain used during reading in older children and adults, Vinci-Booher found.

"This could be one of the ways that early experiences actually translate to long-term life outcomes," she says. "These visually demanding, fine motor actions bake in neural communication patterns that are really important for learning later on."

Ditching handwriting instruction could mean that those skills don't get developed as well, which could impair kids' ability to learn down the road.

"If young children are not receiving any handwriting training, which is very good brain stimulation, then their brains simply won't reach their full potential," says van der Meer. "It's scary to think of the potential consequences."

Many states are trying to avoid these risks by mandating cursive instruction. This year, California started requiring elementary school students to learn cursive , and similar bills are moving through state legislatures in several states, including Indiana, Kentucky, South Carolina and Wisconsin. (So far, evidence suggests that it's the writing by hand that matters, not whether it's print or cursive.)

Slowing down and processing information

For adults, one of the main benefits of writing by hand is that it simply forces us to slow down.

During a meeting or lecture, it's possible to type what you're hearing verbatim. But often, "you're not actually processing that information — you're just typing in the blind," says van der Meer. "If you take notes by hand, you can't write everything down," she says.

The relative slowness of the medium forces you to process the information, writing key words or phrases and using drawing or arrows to work through ideas, she says. "You make the information your own," she says, which helps it stick in the brain.

Such connections and integration are still possible when typing, but they need to be made more intentionally. And sometimes, efficiency wins out. "When you're writing a long essay, it's obviously much more practical to use a keyboard," says van der Meer.

Still, given our long history of using our hands to mark meaning in the world, some scientists worry about the more diffuse consequences of offloading our thinking to computers.

"We're foisting a lot of our knowledge, extending our cognition, to other devices, so it's only natural that we've started using these other agents to do our writing for us," says Balasubramaniam.

It's possible that this might free up our minds to do other kinds of hard thinking, he says. Or we might be sacrificing a fundamental process that's crucial for the kinds of immersive cognitive experiences that enable us to learn and think at our full potential.

Balasubramaniam stresses, however, that we don't have to ditch digital tools to harness the power of handwriting. So far, research suggests that scribbling with a stylus on a screen activates the same brain pathways as etching ink on paper. It's the movement that counts, he says, not its final form.

ChatGPT vs. ChatGPT Plus: Is a paid subscription still worth it?

When  GPT-4  was OpenAI's most powerful artificial intelligence large language model (LLM), paying for a subscription to ChatGPT Plus --  which costs $20 a month  -- made sense. But now that OpenAI announced the availability of GPT-4o, I'm not so sure. 

With this latest update, OpenAI revealed an omnimodel that makes GPT-4-level intelligence available for all, so you won't need a Plus subscription to access it. What's more, free users can now access features that were previously reserved for paid subscribers, including GPT Store access to use custom GPT bots; the Memory feature to give their conversations a sense of continuity; uploading photos and documents to discuss them with ChatGPT; browsing the web to give more current context; and advanced data analysis. 

Also: 6 ways OpenAI just supercharged ChatGPT for free users

These changes can make it hard to determine who will find free ChatGPT adequate and who should spring for a Plus subscription. As a ChatGPT Plus subscriber, I'll explain below in exactly which cases you should use one or the other. Once GPT-4o is widely available, I'll test it to see how it performs for free users and ChatGPT Plus subscribers and report if any further differences arise.

You should use ChatGPT Plus if...

1. you use chatgpt a lot more than the average user.

With GPT-4o giving free users many of the same capabilities that were only available behind a Plus subscription, the reasons to sign up for a monthly fee have dwindled but are not completely gone. Free ChatGPT users will be limited in the number of messages they can send with GPT-4o, depending on usage and demand; however, OpenAI doesn't specify exactly what that limit is. 

Also:  Microsoft Copilot vs. Copilot Pro: Is the subscription fee worth it?

OpenAI says ChatGPT will switch automatically to GPT-3.5 when free users reach their limit. ChatGPT Plus subscribers have five times the capacity of free users. Paid users will be able to ask GPT-4o five times as many questions as free users and will still have access to GPT-4 when they exceed their limit. We expect OpenAI will increase the limits for GPT-4o for both free and paid users. 

2. You can't wait

OpenAI says it is beginning to roll out GPT-4o to ChatGPT Plus, Team, and ChatGPT free users today, with Enterprise users coming soon. During the Spring Update live stream, OpenAI CTO Mira Murati announced that the new GPT-4o model and the rest of the updates will roll out iteratively to customers over the next few weeks. This means that only a fraction of ChatGPT users currently have access to the new features, with this number increasing shortly.

Also:  How to subscribe to ChatGPT Plus (and why you should)

If you don't want to wait until you get the new update in your account to use Plus features as a free subscriber, you can get a Plus subscription now to stave off the excitement. Note that you can cancel the subscription whenever you want.

ChatGPT Plus users also still get early access to new features that OpenAI rolls out, including the new ChatGPT desktop app for macOS. Soon, this early access will include the new Voice Mode that rolls out over the coming weeks. OpenAI also will launch a Windows version of the app later this year.

You should use free ChatGPT if...

1. you don't want to pay a monthly fee.

When GPT-4o is available, ChatGPT users will no longer need a Plus subscription to access most of the features that initially attracted subscribers. OpenAI is making GPT-4o available to all users, whether they are paying or not. 

ChatGPT free users will be able to access the multimodal GPT-4o with GPT-4-level intelligence, get responses from the web, use advanced data analysis, upload files and photos to discuss with the chatbot, access custom GPTs in the GPT Store, and have more helpful experience with Memory -- all of which used to be ChatGPT Plus benefits.

Although it's unclear whether free users can generate images natively in GPT-4o (OpenAI did not disclose this during the event), free users will have access to GPT bots in the GPT Store. If DALL-E access remains a Plus feature, free users can still access the DALL-E bot in the GPT Store. 

2. You're a casual ChatGPT user

There is no need to upgrade to a ChatGPT Plus membership if you're just a casual user who doesn't reach the usage limits of GPT-4o. The new GPT-4o model is rolling out to ChatGPT free users with usage limits beginning today, but OpenAI hasn't specified this limit. Plus users will have a message limit that is five times greater than that of free users, with Team and Enterprise users getting even higher limits.

Also:  ChatGPT vs. Bing Chat vs. Google Bard: Which is the best AI chatbot?

If you're a free user who doesn't use ChatGPT often and stays within the usage limit, you wouldn't get much benefit from a ChatGPT Plus subscription now. I expect OpenAI will amend the subscription benefits or the price as time passes and GPT-4o becomes widely available.

This study aimed to evaluate the impact of APOE4 homozygosity on Alzheimer’s disease (AD) by examining its clinical, pathological and biomarker changes to see whether APOE4 homozygotes constitute a distinct, genetically determined form of AD. Data from the National Alzheimer’s Coordinating Center and five large cohorts with AD biomarkers were analyzed. The analysis included 3,297 individuals for the pathological study and 10,039 for the clinical study. Findings revealed that almost all APOE4 homozygotes exhibited AD pathology and had significantly higher levels of AD biomarkers from age 55 compared to APOE3 homozygotes. By age 65, nearly all had abnormal amyloid levels in cerebrospinal fluid, and 75% had positive amyloid scans, with the prevalence of these markers increasing with age, indicating near-full penetrance of AD biology in APOE4 homozygotes. The age of symptom onset was earlier in APOE4 homozygotes at 65.1, with a narrower 95% prediction interval than APOE3 homozygotes. The predictability of symptom onset and the sequence of biomarker changes in APOE4 homozygotes mirrored those in autosomal dominant AD and Down syndrome. However, in the dementia stage, there were no differences in amyloid or tau positron emission tomography across haplotypes, despite earlier clinical and biomarker changes. The study concludes that APOE4 homozygotes represent a genetic form of AD, suggesting the need for individualized prevention strategies, clinical trials and treatments.
