Created: May 29 2013


This video demonstrates how you can run the equivalent of a repeated measures ANOVA, when you have ordinal data, using a Friedman test. It also illustrates how you can use the Kendall's W test as an estimate of effect size for the same data. Finally, it illustrates how you can use the Wilcoxon signed-rank test as a follow up to determine what scores are significant.
