John Wilder Tukey (/ ˈtuːki /; [3] June 16, 1915 – July 26, 2000) was an American mathematician and statistician, best known for the development of the fast Fourier Transform (FFT) algorithm and the …

The Tukey Test (or Tukey procedure), also called Tukey’s Honest Significant Difference test, is a post-hoc test based on the studentized range distribution. An ANOVA test can tell you if your results are …

Nov 26, 2018 · The Tukey test is a post hoc test in that the comparisons between variables are made after the data has already been collected. This differs from an a priori test, in which these …

Tukey is credited with the invention of many methods, both graphical and numerical, that are extremely effective in statistical applications. Tukey has done work in time series analysis, exploratory data …

Oct 30, 2023 · Tukey test, also known as Tukey’s Honest Significant Test (HSD) test, is a post-hoc statistical test used to determine whether the means of two sets of data are statistically different from …

The Tukey test is a post hoc test used in statistics after an ANOVA test has rejected the null hypothesis. Its purpose is to identify which specific pairs of group means are significantly different from each other.

Tukey popularized exploratory data analysis. This is the practice of looking at data summaries, especially graphical summaries, before conducting any inference.

But it doesn't tell you which groups differ from which (In the T-test, there are only two groups, so the question does not arise). This is where a Tukey's post-hoc test comes in.

Tukey discovered and named the jackknife procedure meant to provide a general estimate of variance. It evaluates a broadly computable indication of the uncertainty of an estimate by judiciously combining …

There are several multiple comparison procedures that can be employed, but we will start with the one most commonly used, the Tukey procedure. In the Tukey procedure, we compute a "yardstick" value …
