Friedman Anova by Ranks

In this tutorial, we show how to use the FRIEDMAN’S ANOVA BY RANKS component. We use this test when we want to check the null hypothesis that K related (matched) samples come from the same population. That matching can be achieved by studying the same group of individuals under each of the K conditions (repeated measure with various conditions).

Keywords: comparison of population, matched samples, analysis of variance, ranks, nonparametric, ANOVA
