A Kruskal-Wallis Test SPSS 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.


ANCOVA SPSS is short for Analysis of Covariance.
It is a combination of an ANOVA and a regression analysis.
It can include more than one covariate, and SPSS handles up to ten.SPSS tutor dedicates a number of sections of our enhanced one-way ANCOVA guide to help you get valid results while running the statistical tests on these assumptions.
