Section 8 of the Review Sheet

I asked Dr. Clements what you would need to understand about Section 8) "Know how models that mix random effects and fixed effects behave and how models that mix Repeated Measured and Randomized Groups behave. Understand the similarities and differences between such a mixed factorial model and a randomized effects factorial model."

She said something very similar to what TJ said in the review. Both random effects and repeated measures variables influence the whole model in that they change the way in which effects are tested. So if there is one random effect IV, it changes the way all IVs are evaluated (against what error term). Same goes for repeated measure.

You should be able to recognize whether there is either a repeated measure or a random effect from the data as opposed to analyses that don't include either.
