Mann Whitney U test - Clarification on numerical outputs in SPSS

  1. Nov 23, 2011 #1
    Hello to all!

    I was wondering if anyone would help clarify a couple of things please.

    I have two data sets.

    The first data set has two grouped variables.

    The second data set has eight independent variables (let's call them learning methods)

    My understanding is that the aim of this is to compare the two variables in the group with each method.

    I ran off a Mann Whitney U test in SPSS with these data.

    It's outputted in a nice table which includes 8 Mann Whitney U values and 8 Asymp.Sig. vaues. However, I am not sure what some of the values are representing.

    For example, the Mann-Whitney U figure for one method is 49 and the Asymp.Sig (2 tailed) figure is 0.53

    What do these values mean? How do these figures inform the two groups which have been compared? I'm not sure what the values are saying.

    Thank you very much in advance.
