Hi! I need to compare the expression of ~220 genes between two groups (n = 62 and n = 777). I have a dataframe with Z-scores for the expression of those genes (they were actually part of the same group, but I split them based on some criteria, but the z-scores were calculated using them as a group). I have no access to other kind of data like count data. Is it right to use a t-test or a moderated t test to compare them? would be better to use a wilcox test?
Thanks in advance
Thanks, this is what I'll do.
