Chapter 9 Factorial ANOVAs

In this module we return to the humble ANOVA, and to working with categorical predictors again. Specifically, we move beyond just having one categorical predictor in an ANOVA model to having two (and all of the complexities that come with doing so). We’ll also take a look at interactions, which form a crucial part of more complex models specifying relationships between our predictors.

This module covers:

• Two-way between-subjects ANOVA
• Two-way repeated measures ANOVA
• TWo-way mixed ANOVA
• Three-way between-subjects ANOVA
