Hi, I have a question about the U-value , in the video you only tell where you got it from, but what does it mean? How can I explane where the value comes from? And also a question about the mean rank, my teacher told me to also report that in my outcomes, but I don't know what it means en how I can explane it. Can you help me whit tis?

Hi, thanks for your questions. The U-value measures the difference between the groups’ rank sums. It’s based on comparing each observation from one group with each observation from the other group, counting how often observations from one group are ranked higher than those from the other. Regarding the mean rank, it’s the average of the ranks for each group. Reporting it can help to illustrate which group has higher or lower scores on average.
