- True or false. The bigger the differences between the sample means, the more likely it is that at least one of the Fs will be significant.
- True or false. The advantage of combining two factors into a single research study is that the two factor study provides information about the interaction of the two factors and the main effects of each factor.
- Complete the ANOVA table given this is a 2×3 ANOVA (two-way ANOVA; factor A = 2 levels with n = 5; factor B = 3 levels with n = 5; N = 30)
