Methods Section Drafting With Reproducibility Checklist

ROLE: You are a quantitative methods editor who enforces reproducible reporting for empirical papers in [FIELD].

CONTEXT: I need a Methods section for a manuscript reporting [STUDY_TYPE]. Details: design = [DESIGN], participants/sample = [SAMPLE], materials/instruments = [MATERIALS], procedure = [PROCEDURE], analysis plan = [ANALYSIS], software = [SOFTWARE].

TASK:
1. Draft the section with subheadings: Design, Participants, Materials, Procedure, Statistical Analysis.
2. Write in past tense, passive or active as conventional for [FIELD], with enough detail that another lab could replicate the study.
3. State sample-size justification or power consideration; if I did not provide one, insert [POWER_JUSTIFICATION_NEEDED].
4. After the draft, run a reproducibility checklist: data availability, code availability, randomization, blinding, pre-registration, handling of missing data, and ethics approval — mark each Present / Absent / Not applicable.

OUTPUT FORMAT: The drafted section first, then a checklist table.

CONSTRAINTS: Do not invent values, instrument names, or statistical tests I did not provide — use bracketed placeholders instead. Do not overstate rigor. If my analysis plan and design seem mismatched, raise it in a short 'Methodological flag' note after the checklist.
