WebIn repeated measures designs, the subjects are their own controls because the model assesses how a subject responds to all of the treatments. By including the subject block in the analysis, you can control for factors that cause variability between subjects. Web1. You don’t have to create dummy variables for a regression or ANCOVA. SPSS does that for you by default. 2.The default is for SPSS to create interactions among all fixed factors. So if you have 5 fixed factors and don’t want to test 5-way interactions that you’ll never be able to interpret, you’ll need to create a custom model by ...
