run; I have 3 subjects (A, B and C). For each subject, i repeat an experient 3 times. So I have 3 quantitave measurements for each subject. Looking at the data, I realize that in each experiment (1, 2 and 3), A < B < C. But for each experiment I don't have the same "order of magnitude" for my quantitative variable, because of manipulation errors. I wanted to do a kruskall-wallis because of the small sample, to test my quantitative variable between my 3 groups. But I don't know how to take into account the fact that there is inter-experimental variability because one and only one CLASS variable must be specified ? And is the kruslll-wallis test the best solution ? Thank you.
