U-statistics | Nonparametric statistics | Statistical tests
The Wilcoxon signed-rank test is a non-parametric statistical hypothesis test used either to test the location of a population based on a sample of data, or to compare the locations of two populations using two matched samples. The one-sample version serves a purpose similar to that of the one-sample Student's t-test. For two matched samples, it is a paired difference test like the paired Student's t-test (also known as the "t-test for matched pairs" or "t-test for dependent samples"). The Wilcoxon test can be a good alternative to the t-test when population means are not of interest; for example, when one wishes to test whether a population's median is nonzero, or whether there is a better than 50% chance that a sample from one population is greater than a sample from another population. (Wikipedia).

Non-Parametric Alternative Hypothesis Tests in Business Statistics
A parametric test may be used when your data are scale level and the assumptions of the test have been met. Each of the parametric tests we have learned about has an alternative non-parametric test that can be used when your data are nominal or ordinal, your scale data are skewed or non-no
