Kendall’s tau

(symbol: τ) a nonparametric measure of the degree of association between two ordinal variables (i.e., rank-ordered data). For example, a researcher could calculate Kendall’s tau to assess how much of a relationship there is between the rankings of students’ performance provided by two observers (e.g., a teacher and a teaching assistant). Also called Kendall’s rank correlation coefficient. [Maurice Kendall]
