Dear FS Experts,

I'm interested in performing Repeated Measures ANOVA 2x2. I have 2 groups and two times (pre and post treatment).

I have checked the tutorial for repeated measures anova and previous emails:

However, it is not clear to me, which steps I have to follow to create the matrix and obtain the results for groupxtime effect.

I would be very grateful if someone could help me with this analysis,

Thank you in advance,

Best Regards
