10 Steps to Write a Methods Section That Gets Published

Key Takeaways

• Draft your methods section early during or before data collection to capture accurate details about procedures, settings, and decisions in real time, reducing gaps in the narrative.

• Use logical subheadings like Study Design, Participant Selection, Data Collection, and Statistical Analysis to help reviewers navigate quickly and signal an organized study.

• Write in past tense throughout, describe procedures with enough step-by-step detail for replication, and cite established methods while fully explaining any modifications or novel approaches.

• Include all critical details about sample size determination, inclusion/exclusion criteria, recruitment methods, demographics, and statistical tests with software versions and significance thresholds.

• Align your methods section with your target journal's specific guidelines, word limits, and required subheadings before writing to avoid major revisions and meet submission standards.

• Verify consistency between your methods and results sections, include ethics approval and blinding statements, and use a reporting guideline checklist (CONSORT, STROBE, PRISMA) to catch common errors before submission.

The methods section is one of the most important parts of any research manuscript. It tells reviewers exactly what you did and how you did it. A weak methods section can lead to desk rejection, even when your findings are strong.

Peer reviewers use this section to judge the quality of your study. They check whether your approach was sound, reproducible, and appropriate. If key details are missing or unclear, they may reject your paper outright. Learning how to write a methods section correctly can significantly improve your chances of acceptance.

This guide walks you through 10 clear, practical steps. Whether you are a PhD candidate, a clinician, or an early-career scientist, these steps will help you write a methods section that satisfies reviewers and meets journal standards. You can also explore our guide on what makes the methods section so critical for additional context.

Why the Methods Section Matters

The methods section does three key things. First, it shows that your study design was appropriate. Second, it allows other researchers to replicate your work. Third, it supports the credibility of your results.

According to Oxford University Press academic publishing guidance, it is generally better to include more relevant methodological detail than too little. This is especially true when word limits allow. The section supports both critical appraisal and replication, two pillars of scientific publishing.

You can find well-indexed published methods sections across disciplines by browsing PubMed, the leading database for biomedical literature.

10 Steps to Write a Strong Methods Section

Step 1: Start Writing Early

Many experienced editors recommend drafting the methods section before or alongside data collection. This approach reduces the risk of omitting key details later. It also keeps your thinking organized from the start.

Starting early means you can document procedures in real time. You will remember exact settings, materials, and decision points more accurately. Waiting until your study is complete often leads to gaps in the narrative.

Step 2: Review Your Target Journal’s Guidelines

Every journal has specific requirements. Some journals require detailed subheadings. Others prefer a continuous prose format. Word limits also vary widely between publications.

Before writing, download your target journal’s author instructions. Note any required or preferred subheadings, word count limits, and formatting rules. Aligning your methods section with these guidelines from the start saves significant revision time later. If you need help interpreting journal requirements, our scientific editing service can assist.

Step 3: Use Logical Subheadings

Subheadings help reviewers navigate your methods section quickly. They also signal that your study was well-organized. Publisher guidance from 2023 recommends using the following subheadings as a baseline framework:

1. Study Design and Setting
2. Selection of Participants or Samples
3. Data Collection or Data Source
4. Intervention or Procedures
5. Measures and Outcomes
6. Statistical Analysis
7. Ethical Approval

Not every study requires all of these. Adapt the subheadings to fit your specific research design. Consistency between your subheadings and the structure of your results section also improves readability.

Step 4: Write in the Past Tense

The methods section describes work that is already complete. Use the past tense throughout. For example, write “Participants were recruited from” rather than “Participants are recruited from.”

There are two common exceptions to this rule. Use the present tense when describing established facts about instruments or validated tools. Also use the present tense when referring to figures or tables that appear in your manuscript.

Step 5: Describe Your Study Design Clearly

Open your methods section by stating the study design. Use precise, recognized terminology. For example, specify whether your study was a randomized controlled trial, a cross-sectional survey, or a retrospective cohort study.

Also state the study setting and time period. This context helps reviewers assess the generalizability of your findings. Many journals use reporting guidelines such as CONSORT or STROBE to standardize how this information is presented. Refer to the appropriate guideline for your study type.

Step 6: Describe Participants or Samples in Detail

Clearly describe who or what was studied. Include all relevant details:

• Inclusion and exclusion criteria
• How participants were recruited or samples were selected
• Sample size and how it was determined
• Relevant demographic or baseline characteristics
• Any exclusions that occurred after enrollment

Missing participant details are one of the most common reasons methods sections receive critical reviewer comments. Be thorough here. If you are unsure whether to include certain details, it is usually safer to include them.

Step 7: Explain Procedures Step by Step

Describe your procedures in enough detail for replication. Explain what was done, in what order, by whom, and under what conditions. This is the replication standard emphasized consistently in editorial guidance since 2023.

Follow a chronological or thematic order, whichever is more logical for your study. Avoid jumping between procedures. Clarity here reflects the quality of your scientific thinking. For more detailed guidance, read our article on best practices for writing a research methodology section.

Step 8: Cite Established Methods, Describe New Ones

You do not need to re-explain well-known procedures in full detail. Instead, cite the original publication where the method was described. This keeps your section concise and credits original authors appropriately.

However, if you modified an established method, explain clearly what you changed and why. Any new or novel methods should be described in full. Reviewers need to evaluate whether your modifications were appropriate and well-justified.

Here is a quick reference for how to handle different types of methods:

Step 9: Report Your Statistical Analysis Clearly

The statistical analysis subsection is closely scrutinized by reviewers. Include the following elements:

• The statistical software used (name and version)
• The specific tests applied to each type of data
• The significance threshold (e.g., p < 0.05)
• How missing data were handled
• Any adjustments made for confounding variables

Be precise. Vague statements like “appropriate statistical tests were used” are not acceptable in most journals. Reviewers expect you to name each test and justify its use. For deeper insights, explore what biostatistics means for your medical manuscript.

Step 10: Include Ethics and Blinding Statements

Most journals require a statement confirming ethical approval for studies involving human participants or animals. Include the name of the approving ethics committee and the approval reference number.

If your manuscript is submitted for blinded peer review, also check whether your methods section contains any details that could reveal your identity or institution. Many journals require authors to remove identifying information before submission. Your methods section should meet these requirements before you submit.

Common Mistakes to Avoid

Even experienced authors make avoidable errors in their methods sections. Here are the most frequent problems that editors and reviewers identify:

• Omitting key details: Missing information about sample size, recruitment, or data collection procedures
• Wrong tense: Using the present tense for completed procedures
• Passive overuse: Excessive passive voice that makes procedures difficult to follow
• Unexplained choices: Failing to justify why a particular design or test was selected
• Inconsistency with results: Reporting outcomes in the results section that were not mentioned in the methods
• Ignoring journal guidelines: Not following the required reporting checklist for your study type

Reviewing your methods section against a reporting guideline checklist — such as CONSORT, PRISMA, or STROBE — is one of the most effective ways to catch these errors before submission. Learn more by reading our article on 11 expert tips for writing a strong methods section.

Active vs. Passive Voice in the Methods Section

There is ongoing debate about whether to use active or passive voice in scientific writing. Many journals now accept or even encourage active voice because it is clearer and more direct. However, some disciplines and journals still prefer passive voice for procedural descriptions.

The safest approach is to follow your target journal’s style. When in doubt, prioritize clarity over convention. A sentence that is easy to read will always serve your reader better than one that follows tradition at the expense of understanding. Our resource on active vs. passive voice in scientific writing offers further guidance on this topic.

How Long Should a Methods Section Be?

There is no single universal word count for a methods section. Length depends on your study design, your field, and your target journal’s word limit. As a general principle, your methods section should be long enough to allow replication but no longer than necessary.

For most empirical journal articles, the methods section typically ranges from 400 to 1,000 words. Highly complex studies or those using novel techniques may require more. Always check the journal’s instructions for authors and keep your writing concise.
