Question:

Add gender to the analysis in Exercise 1, and compute the mixed-design ANOVA. Request a plot of the cell means, and explain your ANOVA results in terms of the pattern in your graph. Regardless of whether the interaction is significant, follow the mixed-design ANOVA with separate one-way RM ANOVAs (i.e., simple main effects) for each gender.


Data from exercise 1
