Thanks, but I have tried to run pairwise wilcoxon after Kruskal (which
works) after you and another, but am missing something. The table is
clearly wrong with lots of '1's and a few non-sig. p values (eg 0.22).
Kruskal has p = .002. It looks like your table, but no sig values. Wilcoxon
between individual pairs (using menu in Rcmdr) gives much different
results, includ. the so called 1.000s. What's missing?

usually, you will test your assumption first. For example, if normality is
violated, then you better use KW. By using multiple pair-wised t-test, you
are increasing chance of getting Type 1 Error. That is what Post-hoc test
comes in handy(e.g Tukey HSD test).

Thanks for the video, very useful indeed. But I have a more complex
analysis to do, I have measurements both before and after an intervention
((repeated measures) on 4 independent groups, and I need to compare the
measurements using non parametric tests as the data is skewed. I understand
it will be a mix of kruskal wallis and Friedman but I don't know hoe to do
it, can you please help ??)
