In this part (2a) you will be writing the Introduction (literature review and hypothesis). However, you will not complete the ANOVA calculations until you get to part 1b. However, for this part it is not necessary to know the computational methods, only the general rationale. You may wish to choose a One-way ANOVA or a Two-way ANOVA. The one-way (single-factor) design is easier to construct, but the two-way (two-factor) design gives you more to discuss.
