I am running a Kruskal-Wallis and selected All Pairwise Multiple Comparisons. I assume the Multiple Comparisons use the Mann-Whitney U test, but I don't see that the p values are corrected with Bonferroni. I assume, then, that I need to multiply each p value by 3 (I have three comparisons) in order to apply the Bonferroni Correction. Is that right?voltants.com  · oneway— One-way analysis of variance 5 We find that the average weight was largest when we used fertilizer concentration 1.

Stata has three built-in pairwise methods (sidak, bonferroni and scheffe) in the oneway command. Although these options are easy to use, many researchers consider the methods to be too conservative for pairwise comparisons, especially when the are many levels. voltants.com  · You would not use the Bonferroni adjustment on the Kruskal-Wallis test itself.

Mann-Whitney test for between-groups comparisons with Bonferroni correction for multiple comparisons (altogether 10 comparisons).

I have performed Kruskal-Wallis one-way analysis of variance (which came up significant) and after that I had to check which groups were significantly different.
