The Kruskal-Wallis is the non-parametric version of one-way ANOVA. Kruskal-Wallis is applied under the same conditions as one-way ANOVA, except that the dependent variable need not be normally distributed for Kruskal-Wallis. Kruskal-Wallis is a more stringent test than one-way ANOVA, so if the dependent variable is normally distributed, one-way ANOVA is preferable.
