Perform a Kruskal Wallis Test with this free online calculator.

The Kruskal-Wallis test can be used to see if there are significant differences between an independent categorical variable and a continuous dependent variable. It does not depend on a distribution (it is non-parametric), so it can be used when the assumptions of one-way ANOVA are not met.
