Sphericity violation in RM Anova
Posted: Thu Mar 07, 2024 5:45 pm
I am doing an RM anova, to compare repeated measures of 3 subjects in 4 different conditions. In the sphericity check, only the 4th condition is violated. I understand then that I must do a Welch anova.
Would it be correct in this case to perform only the Welch Anova for condition 4 and report the results of the other 3 conditions according to the RM Anova analysis?
Would there be any particularity in this case in writing the results? I'm wondering if I should put any specific mention or simply describe how the tests that have been carried out are normally done.
