Meaning it tests for an overall difference between the variables in the model, i.e. at least one of the groups is statistically significantly different than the others. However, if the ANOVA is significant one cannot tell which groups differ. Factorial ANOVA: Main Effects, Interaction Effects, and Interaction Plots Advertisement Two-way or multi-way data often come from experiments with a factorial design . Assumptions of the Factorial ANOVA. The factorial ANOVA has several assumptions that need to be fulfilled – (1) interval data of the dependent variable, (2) normality, (3) homoscedasticity, and (4) no multicollinearity.

We started out looking at tools that you can use to compare two groups to one another, most notably the \(t\)-test (Chapter 13). Then, we introduced analysis of variance (ANOVA) as a method for comparing more than two groups (Chapter 14).

Dr. Tim Urdan, author of Statistics in Plain English, demonstrates how to interpret a factorial ANOVA conducted using SPSS. Like one-way ANOVA, factorial ANOVA is a tool for testing certain types of hypotheses about population means. So a sensible place to start would be to be explicit about what our hypotheses actually are. Factorial (two-way) analysis of variance; evaluating main effects and interactions; balanced vs. unbalanced designs and the use of type II/III sum-of-squares To make it blunt: in an independent ANOVA (not a mixed-design or even repeated-measures ANOVA) you measure your DV always "between" subjects, i.e.
