Hello,
I want to compare two groups, a group with a disease and a control group that look to photographs of humans and birds. For the group of humans I grouped the photos into 6 conditions and for the group of humans I did the same, meaning the the same 6 conditions. My natural thought was to do a Repeated measures ANOVA with disease group and control group as between subjects and two levels of within subjects, first level human/bird and the other level with the 6 conditions. However, I have 60 photos of humans and 21 photos of birds. So, the sample is a bit unbalance. In this case, is the Repeated measures ANOVA the correct analysis? If not, what is the best analyses to compare the performance between two groups and within to different levels? Thank you for your help.
