ADVANCED STATISTICS LAB

Run transparent inference tests, then check the assumptions behind them.

Use t-tests, correlation and regression, or one-way ANOVA with clearly labeled methods, p values, and assumptions. Results support analysis; they do not replace research design or expert review.

INFERENCE WORKSPACE

One-sample t

BROWSER-ONLY

Compare one sample mean to a selected reference mean.
