The following results are from an independent-measures, two-factor study with n = 5 participants in each treatment condition.

a. Use a two-factor ANOVA with α = .05 to evaluate the main effects and the interaction.
b. Test the simple main effects using α = .05 to evaluate the mean difference between treatment A1 and A2 for each level of factor B.
