Показать описание
(Part 3) I demonstrate how to perform and interpret Cochran's Q in SPSS. This test is suitable for testing the difference between percentages (or proportions) derived from dichotomously scored data associated with within-subjects design with two or more levels.

Thanks for your video. It's very useful for me, but I've a question. Is any faster post hoc if I have more related, dichotomous samples or I have to do Cochran's Q test for every pair?
