Nonparametric tests do not depend on the assumption that values were sampled from Gaussian distributions. This section explains the general idea of nonparametric tests. Later sections explain individual tests:

Wilcoxon signed rank test

Mann-Whitney and Kolgmogorov-Smirnov tests

Wilcoxon matched pairs test

Kruskal-Wallis test

Friedman's test
