Hello everybody
I am doing some research in sleep medicine where I compare the test results of different sleep and vigilance tests. Within these different vigilance test results, the data is sorted in different patient groups. Since my data is non-normally distributed, I performed a Kruskal-Wallis test in order to assess whether there were significant differences among the values obtained for each diagnostic group in each sleep test. Then I performed a Post Hoc test in order to assess between which diagnostic groups these differences where. In order to show which differences between which groups were more important, I performed an Effect Size calculation on each group comparison.
Now I would like to show, e.g. that the difference between patient groups A and B, is greater in Sleep Test X than in Sleep Test Y. I suspect that simply comparing the Effect Size results across Sleep Test samples would be incorrect. Does somebody know how I can correctly perform this task?
My goal is to show that certain diagnostic patient groups are more easily differentiated from others in certain Sleep Tests than in others.
Thank you very much for your support!
