The Kruskal-Wallis test does not require that sample sizes be equal across all groups; it can handle unequal sample sizes. This test is a non-parametric method used when the assumption of normality for ANOVA is violated. It assumes that the samples are independent, that the data are continuous or ordinal, and that the populations have identical distributions except possibly for differences in the median.
