Kendall Test - English Definition & Meaning

Definition

The Kendall test (or Kendall's tau) is a non-parametric statistical test used to measure the ordinal association between two variables. It determines the degree to which two variables tend to increase or decrease together. ➕ It's particularly useful when data is not normally distributed or is ranked. Think of it as judging a dance competition; you rank the dancers, not just score them. It's used in various fields, including economics and social sciences.

Etymology

The Kendall test is named after statistician Maurice Kendall, who developed the test in 1938. 'Tau' (τ) is the Greek letter used to represent the Kendall correlation coefficient. The test provides a measure of the similarity in the ordering of two sets of data. Kendall's work contributed significantly to non-parametric statistics.
