Writing Research Papers

• Research Paper Structure

Whether you are writing a B.S. Degree Research Paper or completing a research report for a Psychology course, it is highly likely that you will need to organize your research paper in accordance with American Psychological Association (APA) guidelines.  Here we discuss the structure of research papers according to APA style.

Major Sections of a Research Paper in APA Style

A complete research paper in APA style that is reporting on experimental research will typically contain a Title page, Abstract, Introduction, Methods, Results, Discussion, and References sections. 1  Many will also contain Figures and Tables and some will have an Appendix or Appendices.  These sections are detailed as follows (for a more in-depth guide, please refer to " How to Write a Research Paper in APA Style ”, a comprehensive guide developed by Prof. Emma Geller). 2

What is this paper called and who wrote it? – the first page of the paper; this includes the name of the paper, a “running head”, authors, and institutional affiliation of the authors.  The institutional affiliation is usually listed in an Author Note that is placed towards the bottom of the title page.  In some cases, the Author Note also contains an acknowledgment of any funding support and of any individuals that assisted with the research project.

One-paragraph summary of the entire study – typically no more than 250 words in length (and in many cases it is well shorter than that), the Abstract provides an overview of the study.

Introduction

What is the topic and why is it worth studying? – the first major section of text in the paper, the Introduction commonly describes the topic under investigation, summarizes or discusses relevant prior research (for related details, please see the Writing Literature Reviews section of this website), identifies unresolved issues that the current research will address, and provides an overview of the research that is to be described in greater detail in the sections to follow.

What did you do? – a section which details how the research was performed.  It typically features a description of the participants/subjects that were involved, the study design, the materials that were used, and the study procedure.  If there were multiple experiments, then each experiment may require a separate Methods section.  A rule of thumb is that the Methods section should be sufficiently detailed for another researcher to duplicate your research.

What did you find? – a section which describes the data that was collected and the results of any statistical tests that were performed.  It may also be prefaced by a description of the analysis procedure that was used. If there were multiple experiments, then each experiment may require a separate Results section.

What is the significance of your results? – the final major section of text in the paper.  The Discussion commonly features a summary of the results that were obtained in the study, describes how those results address the topic under investigation and/or the issues that the research was designed to address, and may expand upon the implications of those findings.  Limitations and directions for future research are also commonly addressed.

List of articles and any books cited – an alphabetized list of the sources that are cited in the paper (by last name of the first author of each source).  Each reference should follow specific APA guidelines regarding author names, dates, article titles, journal titles, journal volume numbers, page numbers, book publishers, publisher locations, websites, and so on (for more information, please see the Citing References in APA Style page of this website).

Tables and Figures

Graphs and data (optional in some cases) – depending on the type of research being performed, there may be Tables and/or Figures (however, in some cases, there may be neither).  In APA style, each Table and each Figure is placed on a separate page and all Tables and Figures are included after the References.   Tables are included first, followed by Figures.   However, for some journals and undergraduate research papers (such as the B.S. Research Paper or Honors Thesis), Tables and Figures may be embedded in the text (depending on the instructor’s or editor’s policies; for more details, see "Deviations from APA Style" below).

Supplementary information (optional) – in some cases, additional information that is not critical to understanding the research paper, such as a list of experiment stimuli, details of a secondary analysis, or programming code, is provided.  This is often placed in an Appendix.

Variations of Research Papers in APA Style

Although the major sections described above are common to most research papers written in APA style, there are variations on that pattern.  These variations include: 

• Literature reviews – when a paper is reviewing prior published research and not presenting new empirical research itself (such as in a review article, and particularly a qualitative review), then the authors may forgo any Methods and Results sections. Instead, there is a different structure such as an Introduction section followed by sections for each of the different aspects of the body of research being reviewed, and then perhaps a Discussion section. 
• Multi-experiment papers – when there are multiple experiments, it is common to follow the Introduction with an Experiment 1 section, itself containing Methods, Results, and Discussion subsections. Then there is an Experiment 2 section with a similar structure, an Experiment 3 section with a similar structure, and so on until all experiments are covered.  Towards the end of the paper there is a General Discussion section followed by References.  Additionally, in multi-experiment papers, it is common for the Results and Discussion subsections for individual experiments to be combined into single “Results and Discussion” sections.

Departures from APA Style

In some cases, official APA style might not be followed (however, be sure to check with your editor, instructor, or other sources before deviating from standards of the Publication Manual of the American Psychological Association).  Such deviations may include:

• Placement of Tables and Figures  – in some cases, to make reading through the paper easier, Tables and/or Figures are embedded in the text (for example, having a bar graph placed in the relevant Results section). The embedding of Tables and/or Figures in the text is one of the most common deviations from APA style (and is commonly allowed in B.S. Degree Research Papers and Honors Theses; however you should check with your instructor, supervisor, or editor first). 
• Incomplete research – sometimes a B.S. Degree Research Paper in this department is written about research that is currently being planned or is in progress. In those circumstances, sometimes only an Introduction and Methods section, followed by References, is included (that is, in cases where the research itself has not formally begun).  In other cases, preliminary results are presented and noted as such in the Results section (such as in cases where the study is underway but not complete), and the Discussion section includes caveats about the in-progress nature of the research.  Again, you should check with your instructor, supervisor, or editor first.
• Class assignments – in some classes in this department, an assignment must be written in APA style but is not exactly a traditional research paper (for instance, a student asked to write about an article that they read, and to write that report in APA style). In that case, the structure of the paper might approximate the typical sections of a research paper in APA style, but not entirely.  You should check with your instructor for further guidelines.

Sections of a Scholarly Journal Article About Scientific Research

Let's look at the different parts of a scholarly article that presents scientific research:

• Brief description of the article
• You can read this to decide whether you want to read the entire article.

Introduction:

• Description of the problem, or the research question, and why this study is being done
• Sometimes includes a short literature review (a discussion of other sources, such as books and articles, that informed the author(s) of this article)

• The main part of an article is its body text.
• This is where the author analyzes the argument, research question, or problem. This section also includes analysis and criticism.
• The author may use headings to divide this part of the article into sections. 

Scientific research articles may include these sections:

• Literature review (Discussion of other sources, such as books and articles, that informed the author(s) of this article)
• Methods (Description of the way the research study was set up and how data was collected)
• Results (Presentation of the research study results)
• Discussion (Discussion of whether the results of the study answer the research question)

You may see some of these same sections in articles written by scholars who work in the humanities (fields of study that include literature, philosophy, history, languages, and the arts).

Conclusion:

• Wraps up the article.
• This section isn't always labeled. 
• Description of how this article or research study contributes to or builds on the previous research of other scholars.
• Also includes ideas for future research others might do on this topic.

What are the Sections of a Research Proposal?

Research proposals that are written by graduate students or academic researchers typically follow a similar format consisting of headings and sections that explain the purpose of the research, specify the scope and scale of the study, and argue for its importance in contributing to the scientific literature. Knowing how to write a research proposal checklist  is crucial to getting your dissertation or thesis project accepted.

Although the research proposal sections may vary depending on whether it is a grant,  doctoral dissertation , conference paper, or professional project, there are certainly some sections in common. This article will cover sections you will often see in research proposals, explain their purpose, and provide a sample research proposal template.

What are the sections of a research proposal?

Let’s take a look at each section of a research proposal:

• Overall purpose
• Background literature
• Research question
• Definitions of terms and nomenclature
• Research methodology
• Problems and limitations
• Required resources and budget
• Ethical considerations
• Proposed timetable

What is the purpose of each research proposal section?

The research proposal sections and headings above resemble a fully edited and published academic journal article, which you probably can recognize if you are a new PhD or master’s graduate student who is just starting out reading peer-reviewed academic journal articles. 

However, the purpose of each heading in a research proposal is quite different from that of a final article. 

Purpose : To explain briefly, in a few words, what the research will be about.

What you should do:  Give your research proposal a concise and accurate title. Include the name of your faculty mentor (and his/her academic department).

Note : Title pages for research proposals are generally standardized or specified and provide or summarize basic administrative information‌, such as the university or research institution. Titles should be concise and brief enough to inform the reader of the purpose and nature of the research.

Related Article:  How to choose the best title for your research manuscript

Purpose:  To provide an overview of the study, which you will expand on in detail in later sections of the research proposal.

What you should do:  Provide a brief overview of your project. Include the goals of your research proposal and clearly specify the research questions you want to address. Explain the hypotheses you want to test.

Note : A good summary should emphasize the problems the applicant intends to solve, identify the solution to the problems, and specify the objectives and design‌ ‌of‌ ‌the‌ ‌research. It should also describe the applicant’s qualifications and budget requirements.

Overall purpose.

Purpose:  To state the overall goal of the work in a clear, concise manner.

What you should do : Summarize your problem for someone who is scientifically knowledgeable but potentially uninformed regarding your specific research topic.

Note : The aim or purpose of a research proposal should be results-oriented as opposed to process-oriented. For example, the result of a research study may be “To determine the enzyme involved in X” while the process is “to perform a protein electrophoresis study on mice expressing Y gene.” There should be at least three objectives per proposal. 

Background Literature Review

Purpose : To demonstrate the relationship between the goals of the proposed study and what has already been established in the relevant field of study.

What you should do : Selectively and critically analyze the literature. Explain other researchers’ work so that your professor or project manager has a clear understanding of how you will address past research and progress the literature.

Note : One of the most effective ways to support your research’s purpose and importance is to address gaps in the literature, controversies in your research field, and current trends in research. This will put into context how your dissertation or study will contribute to general scientific knowledge. Learn  how to write a literature review  before writing this section.

Research Question or Hypothesis

Purpose : To state precisely what the study will investigate or falsify.

What you should do : Clearly distinguish the dependent and independent variables and be certain the reader understands them. Make sure you use your terms consistently. Whenever possible, use the same nomenclature.

Note : A research question presents the relationship between two or more variables in the form of a question, whereas a hypothesis is a declarative statement of the relationship between two or more variables. Knowing  where to put the research question in a science paper  is also crucial to writing a strong Introduction section.

Definition of Terms

Purpose : To define the meanings of the key terms used in the research.

What you should do:  Align your term and nomenclature usage throughout your entire research proposal. Clearly define abbreviations and make sure they are understandable to scientists from other disciplines.

Note : Different scientific fields of study often use different terms for the same thing. Further, there are language consistency issues that should be considered. In organic chemistry, there are international standards for naming compounds, but common names are still regularly used, e.g., acetic acid versus ethanoic acid.

Research Methodology

Purpose:  To break down the steps of your research proposal.

What you should do:   Explain how you will achieve‌ ‌your research goals ‌specified‌ ‌earlier using terms that a general reader can understand. Explain your approach, design, and methods.

Note : Your research proposal should explain the broad scope of your research to other researchers‌ ‌in‌ ‌your‌ ‌field. This section represents the most important part of a research proposal and is therefore ‌the‌ ‌primary‌ ‌concern‌ ‌of‌ ‌reviewers. Knowing  how to explain research methodology for reproducibility  is important to explaining your methodology to dissertation or thesis advisors and committees. 

Problems and Limitations

Purpose:  To demonstrate awareness of any study limitations, potential problems, and barriers to answering the research question, and how to deal with them

What you should do:  Thoroughly head off any criticisms before they can torpedo your research proposal. Explain that any limitations or potential conflicts will only delay your research or alter/narrow its scope; they will not fundamentally degrade the importance of your research.

Note : Any research proposal or scientific study will have limitations in its scope and execution. Sometimes it may be a key procedure that is problematic or a material you cannot readily obtain. Discussing limitations is key to demonstrating you are an adept and experienced researcher worth approving.

Related Article:  How to present study limitations and alternatives

Required resources and budget.

Purpose:  To list what resources your research may require and what costs and timelines may affect your completion.

What you should do:  Think as a businessperson. Breakdown what resources are available at your institution or university as well as the required resources you still need. These can be materials, machinery, lab equipment, and computers. Resources can also be human: expertise to perform a procedure and other kinds of collaboration. 

Note : This section underscores why your funding institution or academic committee should fund your university, laboratory team, or yourself for this particular research. 

Ethical Considerations

Purpose:  To state how participants will be advised of

the overall nature and purpose of the study and how informed consent will

be obtained.

What you should do:  Consult with your academic institution, PhD advisor, and laboratory colleagues. Do not gloss over this part since it has legal consequences.

Note : Often, these types of legal disclaimers are well established and readily available in template format from your research institution or university. Just obtain the proper clearance and permission and have the legal authority at your institution check it over.

Read about how  conflicts of interest  should be disclosed in research proposals

Proposed timeline.

Purpose:  To give a projected timeline for planning, completing, verifying, and reporting your research.

What you should do:  Approach this part with a project management style. In an organized fashion, set out a specific timeline for how long each part of your research will take. Identify bottlenecks and specify them.

Note:  Savvy time management is something that comes with lots of research experience. Ask your professor or colleagues if you have questions about how long certain procedures will take.

Purpose:  To provide detailed bibliographic and reference citations.

What you should do:  Use an online citation machine ( APA citation machine , MLA citation machine , Chicago citation machine , Vancouver citation machine ) that can instantly organize your references in any format. Make sure you do this as you go, not saving it for the last when you have lost track.

Note:  The bibliographic format used varies according to the research discipline. Consistency is the main consideration; whichever style is chosen should be followed carefully throughout the entire paper. 

Related Article:  How many references to include in a research proposal?

Purpose : To include any extra materials or information.

What you should do:  Add letters of endorsement or collaboration and reprints of relevant articles if they are not available electronically. In addition to the above, you may want to include data tables, surveys, questionnaires, data collection procedures, clinical protocols, and informed consent documents.

Notes : Many writers tend to attach supporting documents to support their research proposal. But remember, more is not always better. Be sure to only include information that strengthens your case, not simply make it longer.

Note : Savvy time management is something that comes with lots of research experience. Ask your professor or colleagues if you have questions about how long certain procedures will take.

The Bottom Line

Whether your research is academic (PhD or master’s graduate student) or professional (competing for government or private funding), how you organize your research proposal sections is one of the first things evaluators will notice. Many academic reviewers will simply scan and check for key section headings. If any headings are missing or strangely written, they may instantly give the reviewer a bad impression of your proposal. 

One tip before submitting or even writing your research proposal is to search for the best journal to publish your research in and follow the guidelines in the Guide for Authors section, as well as read as many articles from that journal as possible to gain an understanding of the appropriate style and formatting.

The Sections of a Research Article

If you’ve ever read or written almost any type of academic document, you might have noticed that they start with introductions and end with conclusions. However, research articles – as a genre – have other consistent sections as well. The complete list of sections for research articles include the following:

• Introduction
• Discussion/Conclusion

A common acronym for teaching the sections of a research article is IMRD/C. In this book, we will focus heavily on helping you understand each of those IMRD/C sections’ various pieces, including their communicative goals and strategies you can use to achieve those goals. We will also use a visual of an hourglass to demonstrate this IMRD/C organizational structure.

We hope that this graphic along with the explanations and examples in Chapters 3-6 will allow you to deepen your understanding of research writing and become a more successful author.

How to Write the Methods Section of a Research Paper

Writing a research paper is both an art and a skill, and knowing how to write the methods section of a research paper is the first crucial step in mastering scientific writing. If, like the majority of early career researchers, you believe that the methods section is the simplest to write and needs little in the way of careful consideration or thought, this article will help you understand it is not 1 .

We have all probably asked our supervisors, coworkers, or search engines “ how to write a methods section of a research paper ” at some point in our scientific careers, so you are not alone if that’s how you ended up here.  Even for seasoned researchers, selecting what to include in the methods section from a wealth of experimental information can occasionally be a source of distress and perplexity.   

Additionally, journal specifications, in some cases, may make it more of a requirement rather than a choice to provide a selective yet descriptive account of the experimental procedure. Hence, knowing these nuances of how to write the methods section of a research paper is critical to its success. The methods section of the research paper is not supposed to be a detailed heavy, dull section that some researchers tend to write; rather, it should be the central component of the study that justifies the validity and reliability of the research.

Are you still unsure of how the methods section of a research paper forms the basis of every investigation? Consider the last article you read but ignore the methods section and concentrate on the other parts of the paper . Now think whether you could repeat the study and be sure of the credibility of the findings despite knowing the literature review and even having the data in front of you. You have the answer!   

Having established the importance of the methods section , the next question is how to write the methods section of a research paper that unifies the overall study. The purpose of the methods section , which was earlier called as Materials and Methods , is to describe how the authors went about answering the “research question” at hand. Here, the objective is to tell a coherent story that gives a detailed account of how the study was conducted, the rationale behind specific experimental procedures, the experimental setup, objects (variables) involved, the research protocol employed, tools utilized to measure, calculations and measurements, and the analysis of the collected data 2 .

In this article, we will take a deep dive into this topic and provide a detailed overview of how to write the methods section of a research paper . For the sake of clarity, we have separated the subject into various sections with corresponding subheadings.  

Table of Contents

What is the methods section of a research paper ?  

The methods section is a fundamental section of any paper since it typically discusses the ‘ what ’, ‘ how ’, ‘ which ’, and ‘ why ’ of the study, which is necessary to arrive at the final conclusions. In a research article, the introduction, which serves to set the foundation for comprehending the background and results is usually followed by the methods section, which precedes the result and discussion sections. The methods section must explicitly state what was done, how it was done, which equipment, tools and techniques were utilized, how were the measurements/calculations taken, and why specific research protocols, software, and analytical methods were employed.  

Why is the methods section important?  

The primary goal of the methods section is to provide pertinent details about the experimental approach so that the reader may put the results in perspective and, if necessary, replicate the findings 3 .  This section offers readers the chance to evaluate the reliability and validity of any study. In short, it also serves as the study’s blueprint, assisting researchers who might be unsure about any other portion in establishing the study’s context and validity. The methods plays a rather crucial role in determining the fate of the article; an incomplete and unreliable methods section can frequently result in early rejections and may lead to numerous rounds of modifications during the publication process. This means that the reviewers also often use methods section to assess the reliability and validity of the research protocol and the data analysis employed to address the research topic. In other words, the purpose of the methods section is to demonstrate the research acumen and subject-matter expertise of the author(s) in their field.  

Structure of methods section of a research paper  

Similar to the research paper, the methods section also follows a defined structure; this may be dictated by the guidelines of a specific journal or can be presented in a chronological or thematic manner based on the study type. When writing the methods section , authors should keep in mind that they are telling a story about how the research was conducted. They should only report relevant information to avoid confusing the reader and include details that would aid in connecting various aspects of the entire research activity together. It is generally advisable to present experiments in the order in which they were conducted. This facilitates the logical flow of the research and allows readers to follow the progression of the study design.   

It is also essential to clearly state the rationale behind each experiment and how the findings of earlier experiments informed the design or interpretation of later experiments. This allows the readers to understand the overall purpose of the study design and the significance of each experiment within that context. However, depending on the particular research question and method, it may make sense to present information in a different order; therefore, authors must select the best structure and strategy for their individual studies.   

In cases where there is a lot of information, divide the sections into subheadings to cover the pertinent details. If the journal guidelines pose restrictions on the word limit , additional important information can be supplied in the supplementary files. A simple rule of thumb for sectioning the method section is to begin by explaining the methodological approach ( what was done ), describing the data collection methods ( how it was done ), providing the analysis method ( how the data was analyzed ), and explaining the rationale for choosing the methodological strategy. This is described in detail in the upcoming sections.    

How to write the methods section of a research paper  

Contrary to widespread assumption, the methods section of a research paper should be prepared once the study is complete to prevent missing any key parameter. Hence, please make sure that all relevant experiments are done before you start writing a methods section . The next step for authors is to look up any applicable academic style manuals or journal-specific standards to ensure that the methods section is formatted correctly. The methods section of a research paper typically constitutes materials and methods; while writing this section, authors usually arrange the information under each category.

The materials category describes the samples, materials, treatments, and instruments, while experimental design, sample preparation, data collection, and data analysis are a part of the method category. According to the nature of the study, authors should include additional subsections within the methods section, such as ethical considerations like the declaration of Helsinki (for studies involving human subjects), demographic information of the participants, and any other crucial information that can affect the output of the study. Simply put, the methods section has two major components: content and format. Here is an easy checklist for you to consider if you are struggling with how to write the methods section of a research paper .   

• Explain the research design, subjects, and sample details  
• Include information on inclusion and exclusion criteria  
• Mention ethical or any other permission required for the study  
• Include information about materials, experimental setup, tools, and software  
• Add details of data collection and analysis methods  
• Incorporate how research biases were avoided or confounding variables were controlled  
• Evaluate and justify the experimental procedure selected to address the research question  
• Provide precise and clear details of each experiment  
• Flowcharts, infographics, or tables can be used to present complex information     
• Use past tense to show that the experiments have been done   
• Follow academic style guides (such as APA or MLA ) to structure the content  
• Citations should be included as per standard protocols in the field  

Now that you know how to write the methods section of a research paper , let’s address another challenge researchers face while writing the methods section —what to include in the methods section .  How much information is too much is not always obvious when it comes to trying to include data in the methods section of a paper. In the next section, we examine this issue and explore potential solutions.   

What to include in the methods section of a research paper  

The technical nature of the methods section occasionally makes it harder to present the information clearly and concisely while staying within the study context. Many young researchers tend to veer off subject significantly, and they frequently commit the sin of becoming bogged down in itty bitty details, making the text harder to read and impairing its overall flow. However, the best way to write the methods section is to start with crucial components of the experiments. If you have trouble deciding which elements are essential, think about leaving out those that would make it more challenging to comprehend the context or replicate the results. The top-down approach helps to ensure all relevant information is incorporated and vital information is not lost in technicalities. Next, remember to add details that are significant to assess the validity and reliability of the study. Here is a simple checklist for you to follow ( bonus tip: you can also make a checklist for your own study to avoid missing any critical information while writing the methods section ).  

• Structuring the methods section : Authors should diligently follow journal guidelines and adhere to the specific author instructions provided when writing the methods section . Journals typically have specific guidelines for formatting the methods section ; for example, Frontiers in Plant Sciences advises arranging the materials and methods section by subheading and citing relevant literature. There are several standardized checklists available for different study types in the biomedical field, including CONSORT (Consolidated Standards of Reporting Trials) for randomized clinical trials, PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analysis) for systematic reviews and meta-analysis, and STROBE (STrengthening the Reporting of OBservational studies in Epidemiology) for cohort, case-control, cross-sectional studies. Before starting the methods section , check the checklist available in your field that can function as a guide.     
• Organizing different sections to tell a story : Once you are sure of the format required for structuring the methods section , the next is to present the sections in a logical manner; as mentioned earlier, the sections can be organized according to the chronology or themes. In the chronological arrangement, you should discuss the methods in accordance with how the experiments were carried out. An example of the method section of a research paper of an animal study should first ideally include information about the species, weight, sex, strain, and age. Next, the number of animals, their initial conditions, and their living and housing conditions should also be mentioned. Second, how the groups are assigned and the intervention (drug treatment, stress, or other) given to each group, and finally, the details of tools and techniques used to measure, collect, and analyze the data. Experiments involving animal or human subjects should additionally state an ethics approval statement. It is best to arrange the section using the thematic approach when discussing distinct experiments not following a sequential order.  
• Define and explain the objects and procedure: Experimental procedure should clearly be stated in the methods section . Samples, necessary preparations (samples, treatment, and drug), and methods for manipulation need to be included. All variables (control, dependent, independent, and confounding) must be clearly defined, particularly if the confounding variables can affect the outcome of the study.  
• Match the order of the methods section with the order of results: Though not mandatory, organizing the manuscript in a logical and coherent manner can improve the readability and clarity of the paper. This can be done by following a consistent structure throughout the manuscript; readers can easily navigate through the different sections and understand the methods and results in relation to each other. Using experiment names as headings for both the methods and results sections can also make it simpler for readers to locate specific information and corroborate it if needed.   
• Relevant information must always be included: The methods section should have information on all experiments conducted and their details clearly mentioned. Ask the journal whether there is a way to offer more information in the supplemental files or external repositories if your target journal has strict word limitations. For example, Nature communications encourages authors to deposit their step-by-step protocols in an open-resource depository, Protocol Exchange which allows the protocols to be linked with the manuscript upon publication. Providing access to detailed protocols also helps to increase the transparency and reproducibility of the research.  
• It’s all in the details: The methods section should meticulously list all the materials, tools, instruments, and software used for different experiments. Specify the testing equipment on which data was obtained, together with its manufacturer’s information, location, city, and state or any other stimuli used to manipulate the variables. Provide specifics on the research process you employed; if it was a standard protocol, cite previous studies that also used the protocol.  Include any protocol modifications that were made, as well as any other factors that were taken into account when planning the study or gathering data. Any new or modified techniques should be explained by the authors. Typically, readers evaluate the reliability and validity of the procedures using the cited literature, and a widely accepted checklist helps to support the credibility of the methodology. Note: Authors should include a statement on sample size estimation (if applicable), which is often missed. It enables the reader to determine how many subjects will be required to detect the expected change in the outcome variables within a given confidence interval.  
• Write for the audience: While explaining the details in the methods section , authors should be mindful of their target audience, as some of the rationale or assumptions on which specific procedures are based might not always be obvious to the audience, particularly for a general audience. Therefore, when in doubt, the objective of a procedure should be specified either in relation to the research question or to the entire protocol.  
• Data interpretation and analysis : Information on data processing, statistical testing, levels of significance, and analysis tools and software should be added. Mention if the recommendations and expertise of an experienced statistician were followed. Also, evaluate and justify the preferred statistical method used in the study and its significance.  

What NOT to include in the methods section of a research paper  

To address “ how to write the methods section of a research paper ”, authors should not only pay careful attention to what to include but also what not to include in the methods section of a research paper . Here is a list of do not’s when writing the methods section :  

• Do not elaborate on specifics of standard methods/procedures: You should refrain from adding unnecessary details of experiments and practices that are well established and cited previously.  Instead, simply cite relevant literature or mention if the manufacturer’s protocol was followed.  
• Do not add unnecessary details : Do not include minute details of the experimental procedure and materials/instruments used that are not significant for the outcome of the experiment. For example, there is no need to mention the brand name of the water bath used for incubation.    
• Do not discuss the results: The methods section is not to discuss the results or refer to the tables and figures; save it for the results and discussion section. Also, focus on the methods selected to conduct the study and avoid diverting to other methods or commenting on their pros or cons.  
• Do not make the section bulky : For extensive methods and protocols, provide the essential details and share the rest of the information in the supplemental files. The writing should be clear yet concise to maintain the flow of the section.  

We hope that by this point, you understand how crucial it is to write a thoughtful and precise methods section and the ins and outs of how to write the methods section of a research paper .
