Dear prof. David thanks a lot as i noticed your pdf file but i need all types that in SPSS at least the commonest types to teach it in faculty in medicine for post graduates in preparatory exams in MD.
Hello Khaled Almaz I will try to answer your second question. There are many sources on the first question.
1- Here is a Post hoc test (It doesn't matter what, like LSD). Pay attention to everything, especially the boxes I have drawn. Ignore the rest of the results. They are not important here.
2- Here is an Estimated Marginal Means done. Again, pay attention to everything.
3- Now let's see what happens in Kruskal-Wallis?
Therefore, it is better to say that we do not have Post hoc tests in Kruskal-Wallis (as well as Friedman) and what we have is Pairwise Comparisons.
It's good to add here that some software like Prism uses a test called Dunn's for pairwise comparisons in Kruskal-Wallis.
