WebThe 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 … WebJan 4, 2024 · Unlike classic hypothesis tests, which depend on parametric assumptions and/or large sample approximations for valid inference, nonparametric tests use computationally intensive methods to provide valid inferencial results under a wide collection of data generating conditions.
