Hi everyone,

I am using the Kruskal Wallis rank test to see if there are any statistically significant differences in 3 different groups. I have 2 questions (unrelated):

1) How do I determine whether I use the p-values with ties or without ties?

2) is there a statistical test for medians that can account for multiple observations per person (kind of like a GEE)?

Thank you.
