Inferential statistics

Three discussion questions at two hundred words each: the difference between a goodness-of-fit test and a test of independence, a reflection on the week's material, and a plain-language explanation of a chi-square output.

This guide covers the independent-versus-dependent decision that runs through all of them, the one-tailed test question one flags, why p = .000 is never correct, and the arithmetic behind preferring ANOVA to repeated t-tests.
