These statistics make sense because if one group tends to outrank the other group we might suspect that it is drawn from a distribution that stochastically dominates the. P 001953 Comments. Generally it the non-parametric alternative to the dependent samples t-test.
In particular it is suitable for evaluating the data from a repeated-measures design in a situation where the prerequisites for a dependent samples t-test are not met.
Wilcoxon Signed Rank Test 1 Wilcoxon Signed Rank Test This is another test that is a non-parametric equivalent of a 1-Sample t-test.

The Wilcoxon signed-rank test is similar except it is for the case of paired data. Use the parts of the output that demonstrate these results.
