Hi Guys,
I have three grous and their distribution is not normaly distributed so I decided to use Kruskal-Wallis rather than One way ANOVA. The annoying thing is that Kruskal-Wallis tells if there is/isn't a significant difference between the three groups but does not tell from where the difference come if there is. In other words, is the difference (if there is) is between group 1 and 2 or 1 and 3 or 2 and 3. Any ideas how to know these info?
Many thanks in advance
