What Is The Tukey HSD Test? - Sciencing The Tukey HSD test is a way of reporting ANOVA results and determining if the relationship between three independently varying quantities is statistically significant It relies on first collecting values from a standard ANOVA test and then using specialized programs or sites for the Tukey HSD
Tukey Test Tukey Procedure Honest Significant Difference 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 significant overall, but it won’t tell you exactly where those differences lie
How to Perform Tukey’s Test in R - Statology One of the most commonly used post hoc tests is Tukey’s Test, which allows us to make pairwise comparisons between the means of each group while controlling for the family-wise error rate This tutorial explains how to perform Tukey’s Test in R

What is Tukeys method for multiple comparisons? - Minitab Tukey's method for multiple comparisons is used in ANOVA to create confidence intervals for all pairwise differences between factor level means while controlling the family error rate to a level you specify
John Tukey - Utah State University Tukey wrote his first paper in mathematical statistics in 1938 and wrote solely about mathematical statistics starting in 1944 In the 1960s, he began trying to answer how to determine whether two variables are associated and if their association shows causation
Tukeys range test - Wikipedia 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-step multiple comparison procedure and statistical test
