Writing the methods section of a research paper is crucial for ensuring transparency and reproducibility. While it may seem straightforward, careful thought is needed to include essential details without making it overly complex. This section should clearly explain the research process, experimental design, data collection methods, and analysis techniques. Rather than being a dull, technical segment, it should serve as the backbone of the study, justifying its validity and reliability. Well-structured methods section allows others to replicate the study and verify findings, making it a key component of scientific writing.

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 findings3. 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.
Content:
- 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
Format:
- 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 Methods section should enable readers to comprehend your research procedures and replicate the study, if desired. Here’s a structured breakdown of what to incorporate:
Structure
- Follow Journal Guidelines: Start by adhering to the specific requirements provided by the journal. Many journals have prescribed formats and sections.
- Use Standard Checklists: Familiarize yourself with established checklists relevant to your study type (e.g., CONSORT, PRISMA, STROBE) that can help ensure you cover all necessary components.
Organizing Your Methods
- Chronological or Thematic Arrangement: Organize the Methods section in a logical order where you can either follow the timeline of your experiments or group similar methods together thematically.
Detailed Descriptions
- Participants and Subjects: Describe the characteristics of your subjects clearly. This includes:
- Species (if applicable)

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.
