In this Statistics 101 video, we continue our journey of learning about nonparametric methods (nonparametric statistics). Comparing more than two samples with a blocking variable requires different techniques. In parametric statistics, we would use the Two-Way Block ANOVA. The nonparametric version is called the Friedman Test. This video proposes an example problem, sets up a hypothesis test, and then we go into Microsoft Excel and do everything step by step. Enjoy!
