Table of contents: Example 1: Studentized Range Cumulative Distribution Function … WebTukey'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. It can be used to find means that are significantly different from each other.
