Repeated Measures Contrasts

[Stephanie Gorman]

Hello,
I am running a 3x2x2 repeated measures design, and I have  a significant between subjects effect. Since I have 3 groups, I need to run contrasts comparing an average of my first 2 groups with group 3, and group 1 vs. group 2. Does anyone know how to do this using the latest version of SPSS?
Thanks!

What is "subjects" effect? How do you run your repeated measures? using Mixed or General Linear Model?

Stephanie,

 

If you fit the model employing the MIXED procedure, then you can obtain the contrast(s) of interest using the TEST subcommand.
