Kendall's tau singular

Morphology

Kendall's + tau

This is an eponymous technical term: the constituents are a proper name (Kendall's) and a Greek letter (tau), which do not encode the meaning 'a nonparametric measure of association between rankings'. Knowing the two words does not allow a B1 learner to infer the statistical function or sense, so the expression is specialized jargon and opaque.

Etymology

Kendall's tau gets its name from the statistician Maurice Kendall and the Greek letter tau. The idea is to look at every pair of items in two rankings and see if each pair stays in the same order, so that's why it measures the amount of 'agreement' between rankings.
