I'm trying to compute some mann-whitney tests on my datas, and I use the really handy "Realstats".

As you can see on this link, there are several functions available.

As a noob in stats, I used the MANN_EXACT function to gte my p-values, but after reading some articles I wonder if I shouldn't have used the MTEST function. I didn't find anything about the Mann-Whitney exact test on google.

What is the difference between these two ? When should I use each ?

What does the manual say about the difference between the two functions? – Scortchi - Reinstate Monica May 31 '16 at 13:20
This says "Based on the relationship between the Mann-Whitney Test and the Wilcoxon Rank-Sum Test, we can modify the exact test described in Wilcoxon Rank-Sum Exact Test to provide an exact test for Mann-Whitney". But that makes no sense to me... – Dan Chaltiel May 31 '16 at 13:25
