Test selection & execution (parametric ↔ non-parametric)
Design- and assumption-driven test choice with execution: compare_groups (auto Student/Welch/Mann-Whitney, paired t/Wilcoxon, ANOVA/Welch ANOVA/Kruskal, RM-ANOVA/Friedman with effect sizes, CIs, post hoc, table + figure), explicit non-parametric tests, chi-square family, and factorial/repeated/mixed/ANCOVA designs.

How to run it
Method skills run inside a workflow skill — ask for the analysis in plain language (for example, "run a CFA on these items") and the workflow calls this method with its assumption checks, effect sizes and figures. You can switch it off per project under Customize → Skills.
