List of non parametric statistical tests
WebNonparametric tests include chi-square, Fisher’s exact test and the Mann-Whitney test. Every parametric test has a nonparametric equivalent. For example, if you have parametric data from two independent groups, you can run an independent samples t-test to compare means. If you have nonparametric data, you can run a Mann Whitney test … Web4 mei 2024 · In nonparametric tests, the hypotheses are not about population parameters (e.g., μ=50 or μ 1 =μ 2 ). Instead, the null hypothesis is more general. For example, when comparing two independent groups in terms of a continuous outcome, the null hypothesis in a parametric test is H 0: μ 1 =μ 2.
