Abstract:
|
We often teach ANOVA as an algorithm for generating F statistics and p-values. I'll introduce another way, based on simple ideas of random walks, that makes it clear why we talk about mean squares. This way of presenting ANOVA makes clear the intimate connection between ANOVA and regression, and allows students to move easily beyond the limiting and incorrect notion that ANOVA is just a generalization of the t-test to more than two groups.
