Wilcoxon Test Results

 

Hello everyone, 

I am using Wilcoxon Test for comparing the mean differences between two groups. I do understand the meaning of Prob>ChiSq, however would someone please tell if it relevant for one-sided test or two-sided? 

If it is relevant to two-sided test, how can we calculate the probability for one-sided test.

Thank you,

Ne

(Note that this edit corrects and clarifies my original response. A colleague made me reconsider.)

 

The chi square test, like the t test, can be performed as a lower-tailed, upper-tailed, or two-tailed test. The Wilcoxon test is an upper-tailed test.

Learn it once, use it forever!
