Kruskal Wallis Test Using SPSS

 


A Kruskal Wallis test is a rank-based nonparametric test to find out if there is a statistically significant difference between the medians of three or more independent groups or not. At SPSS tutor we perform a Kruskal-Wallis H test assuming that your distributions are not the same shape and you have to interpret mean ranks rather than medians.
