  2. Tukey's range test - Wikipedia

    en.wikipedia.org/wiki/Tukey's_range_test

    Tukey's range test, also known as Tukey's test, Tukey method, Tukey's honest significance test, or Tukey's HSD (honestly significant difference) test, [1] is a single ...

  3. Post hoc analysis - Wikipedia

    en.wikipedia.org/wiki/Post_hoc_analysis

    Tukey’s Test (see also: Studentized Range Distribution) However, with the exception of Scheffès Method, these tests should be specified "a priori" despite being called "post-hoc" in conventional usage. For example, a difference between means could be significant with the Holm-Bonferroni method but not with the Turkey Test and vice versa.

  4. Newman–Keuls method - Wikipedia

    en.wikipedia.org/wiki/Newman–Keuls_method

    This procedure is often used as a post-hoc test whenever a significant difference between three or more sample means has been revealed by an analysis of variance (ANOVA). [1] The Newman–Keuls method is similar to Tukey's range test as both procedures use studentized range statistics .

  5. Siegel–Tukey test - Wikipedia

    en.wikipedia.org/wiki/Siegel–Tukey_test

    Siegel–Tukey test, named after Sidney Siegel and John Tukey, is a non-parametric test which may be applied to data measured at least on an ordinal scale. It tests for differences in scale between two groups. The test is used to determine if one of two groups of data tends to have more widely dispersed values than the other.

  6. Tukey's test of additivity - Wikipedia

    en.wikipedia.org/wiki/Tukey's_test_of_additivity

    In statistics, Tukey's test of additivity, [1] named for John Tukey, is an approach used in two-way ANOVA (regression analysis involving two qualitative factors) to assess whether the factor variables (categorical variables) are additively related to the expected value of the response variable. It can be applied when there are no replicated ...

  7. Talk:Tukey's range test - Wikipedia

    en.wikipedia.org/wiki/Talk:Tukey's_range_test

    Sheskin describes Tukey as one of a number of unplanned comparisons that are done once significance is detected via ANOVA, aka post-hoc. As Lane says, you could decide to use Tukey a priori, but you would limit your options if you did. If ANOVA indicates a difference, perhaps you don't have to contrast every possible combination to answer the ...

  8. Nonparametric statistics - Wikipedia

    en.wikipedia.org/wiki/Nonparametric_statistics

    Siegel–Tukey test: tests for differences in scale between two groups. Sign test: tests whether matched pair samples are drawn from distributions with equal medians. Spearman's rank correlation coefficient: measures statistical dependence between two variables using a monotonic function.

  9. Tukey–Duckworth test - Wikipedia

    en.wikipedia.org/wiki/Tukey–Duckworth_test

    In statistics, the Tukey–Duckworth test is a two-sample location test – a statistical test of whether one of two samples was significantly greater than the other. It was introduced by John Tukey, who aimed to answer a request by W. E. Duckworth for a test simple enough to be remembered and applied in the field without recourse to tables, let alone computers.
