The alternative hypothesis for the Kruskal-Wallis test is that the mean ranks for the conditions will not all be the same. This means that there is a difference between at least two of the groups being compared. Therefore, if the null hypothesis is rejected, we can conclude that there is evidence for a difference between the groups.
