I have a set of pre and post treatment scores on 8 measures. I'd like to test which of these show significant improvement after treatment. If I use within-subjects t tests it will mean carrying out 8 t tests, and risking type I error.
My textbooks all say that repeated subjects ANOVA is for more than two measures, but I only have 2 (pre & post). There is only one group - no control group or anything. What is the most appropriate test to use?
