Friedman Test Real Statistics Using Excel. The Friedman test is a non parametric alternative to ANOVA with repeated measures. No normality assumption is required. The test is similar to the Kruskal Wallis Test. We will use the terminology from Kruskal Wallis Test and Two Factor ANOVA without Replication. Property 1 Define the test statisticwhere k the number of groups treatments, m the number of subjects, Rj is the sum of the ranks for the jth group. If the null hypothesis that the sum of the ranks of the groups are the same, thenwhen k 5 or m 1. The null hypothesis is rejected when Q. Example 1 A winery wanted to find out whether people preferred red, white or ros wines. They invited 1. 2 people to taste one red, one white and one rose wine with the order of tasting chosen at random and a suitable interval between tastings. Each person was asked to evaluate each wine with the scores tabulated in the table on the left side of Figure 1.

The ranks of the scores for each person were then calculated and the Friedman statistic Q was calculated to be 1. Since p value CHITEST1. Observation Just as for the Kruskal Wallis test, an alternative expression for Q is given bywhere is the sum of squares between groups using the ranks instead of raw data. For Example 1, we can obtain  from the ranked scores i.
