  2. Kruskal–Wallis test - Wikipedia

    en.wikipedia.org/wiki/KruskalWallis_test

    It extends the MannWhitney U test, which is used for comparing only two groups. The parametric equivalent of the KruskalWallis test is the one-way analysis of variance (ANOVA). A significant KruskalWallis test indicates that at least one sample stochastically dominates one other sample. The test does not identify where this stochastic ...

  3. Median test - Wikipedia

    en.wikipedia.org/wiki/Median_test

    The Wilcoxon–MannWhitney U two-sample test or its generalisation for more samples, the KruskalWallis test, can often be considered instead. The relevant aspect of the median test is that it only considers the position of each observation relative to the overall median, whereas the Wilcoxon–MannWhitney test takes the ranks of each ...

  4. One-way analysis of variance - Wikipedia

    en.wikipedia.org/wiki/One-way_analysis_of_variance

    If data are ordinal, a non-parametric alternative to this test should be used such as KruskalWallis one-way analysis of variance. If the variances are not known to be equal, a generalization of 2-sample Welch's t-test can be used. [2]

  5. List of statistical tests - Wikipedia

    en.wikipedia.org/wiki/List_of_statistical_tests

    Statistical tests are used to test the fit between a hypothesis and the data. [1] [2] Choosing the right statistical test is not a trivial task. [1]The choice of the test depends on many properties of the research question.

  6. Mann–Whitney U test - Wikipedia

    en.wikipedia.org/wiki/MannWhitney_U_test

    The MannWhitney test (also called the MannWhitney–Wilcoxon (MWW/MWU), Wilcoxon rank-sum test, or Wilcoxon–MannWhitney test) is a nonparametric statistical test of the null hypothesis that, for randomly selected values X and Y from two populations, the probability of X being greater than Y is equal to the probability of Y being greater than X.

  7. Van der Waerden test - Wikipedia

    en.wikipedia.org/wiki/Van_der_Waerden_test

    The most common non-parametric test for the one-factor model is the Kruskal-Wallis test. The Kruskal-Wallis test is based on the ranks of the data. The advantage of the Van Der Waerden test is that it provides the high efficiency of the standard ANOVA analysis when the normality assumptions are in fact satisfied, but it also provides the ...

  9. Nonparametric statistics - Wikipedia

    en.wikipedia.org/wiki/Nonparametric_statistics

    KruskalWallis one-way analysis of variance by ranks: tests whether > 2 independent samples are drawn from the same distribution. Kuiper's test: tests whether a sample is drawn from a given distribution, sensitive to cyclic variations such as day of the week. Logrank test: compares survival distributions of two right-skewed, censored samples.
