1. Chapters 14, 15, and 16 talk about factorial designs, repeated measure designs, and mixed design. Explain in your own words the difference between these. Give specific examples for which you would choose one method instead of the others.
2. Through Chapters 12 - 16, the author has mentioned homogeneity of variance and sphericity. Why must we consider these factors in General Linear Model (GLM) statistics?
3. Explain in detail a "Goodness-of-Fit" test and when and why this test would be used versus any other analysis test.
