Great video, thank you! Can I use this test on data that ranges between 0.00 -> 0.72 (each value in the dataset is an average of 10 percentages, bounded by 0.00 and 1.00) where zero accounts for about 53% of the data?
Hi Nanna, The Mann Whitney test is just for two variables. If you have three or more, you should use an ANOVA test (for normal data), or the Kruskal Wallis test (for non-normal data). Dr E.
