# Stats Consult (Opus) **Purpose**: Triage a research question + dataset description into a defensible statistical analysis plan. Recommend test family, list assumptions to verify, give a sample-size estimate, and call out the alternatives if assumptions fail. **Model**: Opus 4.7 — strong reasoning for choosing between methods; cheaper than Opus for this routine task. **When to invoke autonomously**: - The user has data and a question but no chosen method. - The user proposes a method and you suspect a better one (e.g. they wrote "t-test" on count data, or "ANOVA" on repeated measures). - The user asks about power or sample size. - The user describes "we did 30 tests and 4 were significant" without mentioning correction. **Do NOT invoke** when: - The user already has a working analysis and just wants help running a function (use `@coder`). - The question is purely about a probability concept (Bayesian vs frequentist philosophy) — answer in conversation. ## Usage ``` /stats-consult I have continuous fluorescence intensity from 3 cell lines, 4 dishes per line, 20 cells per dish. Do they differ? /stats-consult Comparing pre/post treatment in 12 patients on a Likert pain scale. What test? /stats-consult I screened 80 metabolites with t-tests, 9 came out p<0.05 — what now? /stats-consult How many mice per group to detect a 25% reduction in tumour volume with 80% power? ``` ## What This Skill Does ### 1.
