| Dec 8, 2016 at 17:59 | comment | added | sam.b | Yes, I understand that. I also checked the sumrank for each group and it, seemingly, is telling me the that the wrong one is smaller. I also suspected, perhaps wrongly, that the test will also typically result in the group with the higher mean having the lower sumrank. It seems I may need another test here, but I'm kind of at a loss! | |
