Hi
I'm trying to work out a 2 way anova / anova2 or anovan, syntax.
I have 2 groups that have pre and post scores.
I have 4 columns : Pre scores of group A, Post scores Group A, Pre of Group B, Post Group B.
The groups are not the same size
I want to perform a 2 way anova of both time and group effects (between groups).
After reading both anovan and anova2, I'm still having issues how to perform this….
tnx
