3 X 2 X 2 mixed design


New Member
Hi all,

First time posting. I am having trouble 1) figuring out spss output for and 2) interpreting findings for a study I conducted with a 3 (rm) X 2 X 2 design (note that I did not intend such a complicated design but a reviewer wants me to include participant sex as a variable. I can certainly RUN the statistic in spss but now I do not know how to interpret the output. Should I pay more attention to the multivariate tests than the within or between-subjects ones? Is it possible to have a 3-way interaction that is quadratic? If I violate sphericity (I did) how do I deal with it?

My grad program was at an institution that had a stats consultant...I now teach at a smaller school and have nobody to ask.
