Friedman Test Graph. The friedman test is the non parametric alternative to the one way anova with repeated measures. The test is similar to the kruskal wallis test we will use the terminology from kruskal wallis test and two factor anova without replication.
Was the matching effective. It is used to test for differences between groups when the dependent variable being measured is ordinal. A box plot is also useful for assessing differences.

The whole point of using a repeated measures test is to control for experimental variability. Some factors you don t control in the experiment will affect all the measurements from one subject equally so they will not affect the. Under the null hypothesis the chi square distribution approximates the distribution of s. Friedman s test is a nonparametric test that compares three or more paired groups.
