Morphology

phi + correlation

This is a noun+noun label where 'correlation' gives the general meaning and 'phi' functions as a technical label (the Greek letter), so a learner who knows both words can infer this denotes a particular type of correlation. However, the specific property that it measures association between binary variables and its technical interpretation are not derivable from the constituents alone, requiring specialist knowledge.

Etymology

Phi correlation is named after the Greek letter phi, which early statisticians used to label a special number that shows how much two 'yes/no' things go together. So, phi correlation today means a simple measure of the 'relationship' between two 'yes/no' outcomes.
