If I carry out a Kruskal Wallis test and the result comes out as significant, how do I then go about describing those differences and also which groups the difference is present between? For example if I have group A, B and C and I get signiciant difference Do I carry out a certain test for A + B, A + C? Or do I just report percentages/medians? Keep in mind my data was likert scale which I have converted into 1-5 numbers for the purpose of this analysis
Thanks
