A one-way ANOVA is a parametric test which compares the means of three or more groups in terms of one independent variable. This test has several requirements and assumptions in terms of the data and its subsets used in including ones about variance and distributions for the subsets compared. The Kruskal–Wallis test is the non-parametric alternative. One way ANOVAs can be contrasted with two-way ANOVAs which compare groups in terms of two independent variables.
