If the assumptions for ANOVA cannot be met, then the Kruskal-Wallis test is an appropriate substitute. This test does not require the assumption of equal variances or normality and it is used to compare the median ranks of different groups to determine if they are significantly different from each other. Therefore, it is a suitable alternative when the assumptions of ANOVA cannot be met.
