1

What is a Two Way ANOVA?

A two way ANOVA is an analysis of variance. It has a factorial design of two or more independent variables. Each independent variable can have 2 or more levels. The dependent variable is scale

2

What is the difference between a one way ANOVA and a two way ANOVA?

There are 2 independent variables. The two independent variables have an effect in combination

3

What is a factorial ANOVA?

8

What is an interaction?
