Non-parametric Tests

Most of the tests that we study in this website are based on some distribution. These are called parametric tests. Parametric tests require that certain assumptions are satisfied. We now look at some tests that are not linked to a particular distribution. These non-parametric tests are usually easier to apply since fewer assumptions need to be satisfied.

      Rajesh,
      If you press Ctrl-m and select the T Test and Non-parametric equivalents option you can access the Mann-Whitney test for two independent samples and the Wilcoxon tests for one sample and paired samples.
