The explanation of the logic underlying this test and its application are presented. Which test is more appropriate, the Mann Whitney U or the Kolmogorov-Smirnov Z test? Andy Field's Discovering Statistics using SPSS states that K-S Z should be used for small sample sizes: Kolmogorov-Smirnov Z: In Chapter 5 we met a Kolmogorov–Smirnov test that tested whether a sample was from a normally distributed population. Well, a test that was designed for precisely this situation is the Kruskal-Wallis test which doesn't require these assumptions. It basically replaces the weight gain scores with their rank numbers and tests whether these are equal over groups.

The Mann-Whitney doesn't require equal variances unless you're specifically looking for location-shift alternatives. In particular, it is able to test whether the probability of values in the first group are larger than the values in the second group, which is quite a general alternative that sounds like it's related to your original question.
