Week 10: Two-Way ANOVA

Welcome!

This week we explore one final area of ANOVA, a situation where we have multiple explanatory variables. This is called a two-way ANOVA. A two-way ANOVA extends the one-way ANOVA to situations with two categorical explanatory variables. This new methods allows researchers to simultaneously study two variables that might explain variability in the responses and explore whether the impacts of one explanatory variable change depending on the level of the other explanatory variable.
