Given two variables A and B with 35 random data points (generated with Excel in the range of 0 to 1), we applied Analyse -> Nonparametric Tests -> Legacy Dialogs -> 2 connected Samples in SPSS and marked "Wilcoxon" as test, which should perform the the Wilcoxon signed-rank test. All over the internet you find examples of the test reporting a "Z" value. However, our report is
Asymp. Sig. (2-sided): .302
a: Wilcoxon-Test b: based on negative ranks
Why does the test not report a "Z" and how should we modify to obtain a "Z" rather than a "U"?
EDIT: Here's what we did and the output, and the original data is in my Google Drive.
