I'm wondering if someone could please help me with my analysis. I'm running a repeated measures ANOVA on my set of data which has 12 measurements (4 measurements at 3 separate times) and also has a between subjects component of 4 conditions. I need to run my analysis with a comparison between some of these conditions. My first issue is that when I run the analysis I am given a different results for each of the measurements (not an average of measurements across the 4 times) which is what I am interested. Secondly how do I specify the contrasts that I need? Any help would be much appreciated!
