Writing the Methods Section

Enough detail to reproduce the study

The methods section reports exactly what was done — research design, participants and sampling, materials and measures, procedure, and analysis plan — in enough detail for another researcher to replicate the study and judge its validity. It is written in the past tense and reports decisions and their justifications, not a narrative of every false start.

What Is the Methods Section?

The methods section is a structured part of a research report that transparently accounts for how the study was conducted. Its primary purpose is reproducibility: a reader should be able, from this section alone, to replicate the study independently and evaluate the trustworthiness of the findings. The section is written in the past tense because it reports completed actions. A well-written methods section reveals not what the researcher planned to do, but what was actually done — and why those decisions were made.

Core Subsections and Their Content

The methods section typically comprises four core subsections. Research design: whether the study is quantitative, qualitative, or mixed-methods, and the specific experimental or observational design, are explained. Participants and sampling: sample size, inclusion and exclusion criteria, and the sampling strategy are reported. Materials and measures: questionnaires, tests, or instruments are described along with evidence of their validity and reliability. Procedure: how data were collected is laid out step by step. The analysis plan specifies which statistical or qualitative techniques were used and justifies those choices.

An Applied Example

In a study examining the effect of social media use on academic procrastination, the methods section might report: a quantitative, cross-sectional survey design was adopted; 318 undergraduate students were recruited via convenience sampling; the Procrastination Assessment Scale (Cronbach's α = .87) and self-reported daily social media use time served as measures; the online survey was administered over two weeks; Pearson correlation and multiple linear regression were conducted using SPSS 27. This level of detail is sufficient for another researcher to replicate the study.

Common Pitfalls and Best Practice Tips

The most frequent errors are: omitting participant eligibility criteria, skipping psychometric properties of measures, failing to name the analysis software or version, and leaving methodological decisions unjustified. Because the section is not a narrative, only the procedures that actually took place — not pilot failures or abandoned approaches — should be reported. Past tense and passive voice are conventional in many disciplines, though some journals prefer the first person; consistency matters in either case. Following relevant reporting guidelines (APA 7, CONSORT, COREQ, etc.) minimises overlooked details.
