I demonstrate how to perform a mixed-design (a.k.a., split-plot ANOVA within SPSS. I emphasize the interpretation of the interaction effect and explain why it does not matter if the groups differ at time 1 in this type of design.
In this example, there is one within-subjects factor (with 2 levels: pre-test and post-test) and one between-subjects factor (with 2 levels: control group and training group).
SPANOVA
I wrote a blog about this analysis that you can find here:
