What Goes in a Methods Section: The Subsections Graders Check First

The replication standard: the test every methods section must pass

One sentence covers the whole assignment: another trained researcher, reading only your methods section, should be able to repeat your study and get comparable results. That standard decides the level of detail — exact survey instrument names and versions, the manufacturer and model of equipment, the settings an instrument ran at, the exclusion rules applied to participants, the software and its release number. It also decides what to leave out: routine steps any practitioner would assume, and background theory, which belongs in the introduction.

The standard explains why graders read methods first when they suspect a problem. A result that cannot be traced to a procedure is not evidence, so the methods section is the audit trail for every claim the paper makes. In practice the section is written last among drafts or continuously in a lab notebook, then cleaned up — never reconstructed from memory at the end of the project, which is where invented round numbers and unverifiable steps enter. Replication is also why past tense is universal: the study already happened.

The numbers at a glance

Methods subsections and what each must state — the range, and where each row actually shows up in coursework. Skim it first; the sections below explain why the range exists and which row applies to you.

The five subsections, in order

The canonical order runs design, participants or sample, materials or instruments, procedure, analysis — each as its own labeled subsection in an empirical paper, and each answering one grader question. Design names the study type and why it fits the question: within-subjects experiment, cross-sectional survey, quasi-experimental field study. Participants reports the sample size, how people or specimens were selected, the setting, and the demographics that matter to the question. Materials inventories instruments, scales and software with their validation sources and versions. Order matters because each subsection sets up the next one's vocabulary.

Procedure narrates the session in chronological order — recruitment, consent, the task sequence, timing, debriefing — at the granularity of what a replicator would follow. Analysis closes the section by naming the statistical tests, the software, the significance threshold and the assumption checks. A methods section missing any of the five reads as incomplete even when the writing is good, because each subsection maps to a rubric line in almost every empirical course, from introductory psychology research proposals to graduate theses. Head each one with the label your field uses rather than a creative variant.

Tense, voice and person

Methods are written in past tense because the work is done: 'Participants completed a 20-item survey' rather than 'Participants will complete.' Voice is the part with real variation — chemistry and biology lab manuals often preserve the passive ('the solution was heated to 85 degrees'), psychology journals have normalized first person ('we recruited 120 undergraduates'), and most APA 7 journals now prefer active voice wherever it reads cleanly. The safe course is to check the department's lab manual or the journal's author guidelines, then hold one voice consistently across the entire section.

Person rules interact with the passive-voice question, and the methods section is where the old blanket ban breaks down: passive constructions that hide the actor genuinely obscure methods ('the samples were incubated' — by whom, at what setting?), while passive that foregrounds the procedure is exactly right. What graders penalize is not a percentage but confusion — sentences where the reader cannot tell who did what to which sample. First person plural with strong verbs ('we measured absorbance at 5-minute intervals') is the most common pattern in current journal writing across health and behavioral sciences.

How long a methods section should be

Proportion is the reliable guide: methods runs 10-20% of the total paper in most empirical genres. A 2,000-word lab report carries a methods section of 250-350 words; a psychology research report of 10 pages runs 700-1,000; a graduate thesis can devote 1,500-3,000 words across multiple studies. Published articles compress because they cite prior work for standard procedures — 'the Stroop task followed the standard protocol' — a move students should imitate sparingly, citing the source procedure and describing only what differed. Rubrics usually reward proportion over raw length.

Overshoot and undershoot have opposite diagnoses. A bloated methods section usually contains results ('participants scored higher on the second trial') or rationale paragraphs that belong in the introduction; move them. An undersized one usually hides missing subsections — no analysis plan, no participant exclusions, no instrument validation. Count the subsections before counting the words, because a methods section that names all five parts but stays brief reads as efficient, while one that never mentions its analysis plan reads as unfinished regardless of length.

Methods across genres: lab, survey, secondary data and IT

The five-part skeleton survives genre changes with renamed parts. In an IMRaD lab report, participants becomes sample and materials becomes reagents and apparatus, but the logic is identical. Survey research adds distribution mode, response rate and the recruitment funnel — 412 opened the link, 389 consented, 361 completed. Secondary-data studies (a public health paper on BRFSS data, an environmental analysis of USGS records) name the dataset, the years, the variables used and the exclusion criteria, because their 'procedure' is entirely selection and cleaning.

Information technology papers document differently but answer the same grader: a capstone's methods-equivalent section states the environment, the requirements-gathering method, the tools and versions, and the test plan — what was tested, with what data, against which acceptance criteria. Systems analysis assignments add the traceability step, mapping each requirement to the design element that satisfies it. Whatever the field, the replication standard travels intact: a reader who knows the field should be able to take your section and repeat the work without emailing you a single question.

The format check graders run before reading

Graders check mechanics first and content second — a two-minute scan that decides the paper's first impression. The list: correct font and size, double spacing throughout (no stray single-spaced paragraphs), one-inch margins, page numbers in the right corner, the required title-page fields, heading levels used consistently, and references formatted with hanging indents. Each item is trivial; missing two costs measurable points in most rubrics.

Do this scan on the exported PDF, not the working document — export quirks (shifted margins, dropped page numbers, orphaned headings) only appear there. The style switcher below shows the same source formatted in APA 7, MLA 9 and Chicago side by side, which is the fastest way to catch the format you've been half-remembering from the wrong course.
