APA 7 results formatters

Turn a t test, ANOVA, correlation, regression, chi-square, descriptives, reliability, or nonparametric result into a clean, copy-ready APA 7 sentence — plus a standalone check for a reported p-value, the same class of check as the statcheck R package. Every formatter recomputes what it can and preserves italics when pasted into Word or Google Docs.

Solve for the sample size a study needs, or the power a planned sample already has — for t tests, one-way ANOVA, correlation, and chi-square, plus a multilevel/cluster-randomized-trial MDES calculator with sensitivity charts and a proposal-ready methods paragraph.
