JASP and SPSS Mann Whitney p-values differ
I am curious if anyone else gets different results for Mann Whitney U tests on JASP and SPSS. For me, both the p-values and test statistics are coming out differently (although they are close in most cases). Does anyone know why this might be?
It looks like JASP is printing out Wilcoxin (W) statistics when you check the 'Mann-Whitney U' option under independent samples t-tests.
