  • 1.  Non-Parametric Tests

    Posted Mon February 22, 2021 11:07 AM
    Hello,
    What's the difference between making a Mann-Whitney test by Analyze>Non-Parametric Tests>Independent Samples OR  Analyze>Non-Parametric Tests>Independent Samples>Legacy Dialogs>2 Independent Samples?

    Sometimes it gives me 2 different values of the test but same sig.

    What is the problem?

    Thanks!!

    The significance levels are exactly the same from the two procedures.  Look in the Agorithms doc to see how the M-W statistic is calculated in the two procedures.
