The design in Exercise 11 is sometimes called a split-plot / repeated measures (SP/ RM) [1,2], where
Question:
a. Draw a Hasse diagram corresponding to this study, assuming that we are interested in all possible two-way interactions (do not include three-way interactions).
b. Calculate an appropriate ANOVA for this study, assuming that we are interested in testing all two-way interactions. Check the model assumptions and use an appropriate transformation if needed. Some software packages such as Minitab, do not easily analyze a split-plot design with two whole-plot factors. Instead create one new factor (Gender and Division) with 4 levels and use this as the one whole-plot factor in your ANOVA.
c. State your conclusions for this study. Provide appropriate plots and take into account random sampling and random allocation when stating your conclusions.
