The Mann-Whitney U test procedure uses the rank of each case to test whether the groups are drawn from the same population. Mann-Whitney tests that two sampled populations are equivalent in location. The observations from both groups are combined and ranked, with the average rank assigned in the case of ties. The number of ties should be small.
