Thank you, John. Maybe you or other developers think again about
including the non-parametric tests like the Mann Whitney U test in the
GUI as well. Some people may not know that PSPP can do these tests.
I'm looking forward to the next release of PSPP.
Kind regards,

I pushed a fix for this problem.
It will be included in the next release. In the meantime, I suggest that
you use the work-around described by Oliver Walter or build your own
binary from the git repository.
Thanks again for reporting the issue.

Dear Prof. Nuszbaum,
your question would be easier to answer if you described it in more
detail, e.g. by posting your outputs and / or your data sets (if the
sample sizes are small, we could compare the results).

I suspect this is bug 47041 which has been fixed about a year ago.
See https://savannah.gnu.org/bugs/?47041
If you have a build where this has not been fixed, then you can use the
work-around described on that page.

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?
Kind regards,
