Hello! My question is rather into Interpretation of Mann-Whitney in PSPP,
maybe
somebody can help. Would be great! (:
I performed u-test.
My Syntax:
NPAR TESTS
/MANN-WHITNEY = age BY sex (1, 2)
As a result it showed "Asymp. Sig. (2-tailed)" = 0,00 , z was infinite.
To me that means, that the groups are significantly different. Which was
confusing me, as they are almost the same. So I calculated again in two
different Browser-Programs. Both showed p(2-tailed) = 0,91 and z = 0,11
Which is
much more probable for that data.
Does anybody have an idea what I could have done wrong?
This would suggest that one of the groups has no members. Are you sure that 1
and 2
are the correct categorical values? Perhaps it should be 0 and 1 ?
What do you see in the "Ranks" box that the command produces?
