I would like to run a Kruskal Wallis test. There are 5 groups that I need to compare.
Group 1 Sample Size: 37 Group 2 Sample Size: 33 Group 3 Sample Size: 36 Group 4 Sample Size: 16 Group 5 Sample Size: 172
Im concerned with the sample size of the last group.Does it have any effect with the results? A post hoc analysis will be ran if the difference is found significant.
