1. Understand when a "post-hoc" analysis is needed (just based on the analyses we have learned in this course so far) and what it tells us (in other words, why we need it as well we how it helps us understand results of the statistics we use it for).
2. Understand what anR2tells us and what is considered a large, moderate, and small value (according to Cohen). It will help to compare it to what we learned about Cohen'sdvalues (which are different values) and to also know the "general idea" of both (i.e., the characteristics of the "desired values").
3. Understand the main difference between a One-Way ANOVA and Factorial ANOVA (meaning how many independent variables they can have in the analysis) as well as why we would choose the more "complicated" one.
