This module is presented in the style of a brief slide-deck but with interactive components. The setup is a typical two-group analysis and presents the null distribution and alternative distribution conceptually. Students can visualize how effect size, sample size, and alpha affect statistical power, as well as obtain a brief preview to how power analysis for sample size planning may work.
