You continue with the Kruskal Wallis test. However, when you interpret it later, you do no compare the medians of the independent variables, but instead only compare the rank means.
I am in the same boat. I have violated assumption number 4, and doing a Kruskall-Wallis test it has retained the null hypotheses. Do i then need to interpret the mean ranks in my output? They don't quite make sense to me in their values.
Thank you for this video. It was very helpful. I have one question though, how do you include the post test (mann whitney analysis between groups) in your box plots ? other statistics programs such as prism graph pad usually show an asterisk when there is a statistically significant difference found between two groups.

Great video, super clear and thorough!
what do you do if the 4th assumption is violated? As in, the shape of the distributions are different.
