Morphology

Kendall + rank + correlation

The parts 'rank' and 'correlation' transparently suggest a relationship measuring association between ranked variables, so a learner could guess it refers to correlation of ranks. However, 'Kendall' is a proper name denoting a specific, technical nonparametric statistic (Kendall's tau) whose exact meaning and properties cannot be derived from the constituents, making the term only partially predictable to a B1 learner.

Etymology

Kendall rank correlation is named after the statistician Kendall and describes a way to compare two ordered lists. Imagine two judges who rank the same items; Kendall rank correlation looks at pairs that keep the same order versus pairs that swap places, so it measures 'how much the lists agree'.
