Dear Oliver Walter,
I attached a shortened data file and Output (Copy in Excel including syntax). The data base is not very large but results should be the same, or? Maybe its my fault by doing the analysis. The independent Variables are I002_01 to I002_04. The group variable is sum_HL with groups 0 and 1. John Darrington mentioned, that there was an error, which was fixed (I suspect this is bug 47041 which has been fixed about a year ago). So, I installed PSPP new and did the analysis again (see Excel file). I have installed the version: pspp-20160927-daily-32bits-setup.exe Hope you can help, because my students use pspp and I like to be sure that they get correct data output. The attached data is from such a student project. Thanks for your fast response. Kind regards, Mandy Nuszbaum Von: Dr. Walter Statistics [mailto:i...@walter-statistics.com] Gesendet: Samstag, 4.

Kind regards Oliver Walter --- Dr. Walter Statistics Gabelsberger Straße 27 24148 Kiel Am 04.03.2017 um 19:20 schrieb Mandy Nuszbaum: Dear all, I computed Mann-Whitney-U using PSPP and SPSS and compared the results using different data sets. Results are completely different and led to wrong conclusions. Can anyone fix the problem?
