Morphology
biserial + correlation
While 'correlation' is a transparent statistical term, the modifier 'biserial' is technical and not a readily interpretable combination of common English morphemes for a B1 learner (the word is jargon and not found in a general dictionary entry here). Because the specific sense (a coefficient relating a continuous and a dichotomous variable) requires disciplinary knowledge rather than simple composition, the overall expression is not predictable from its parts and would be opaque to most intermediate learners.
Etymology
Biserial correlation comes from bi- meaning 'two' and serial meaning 'series' or 'list'. It gives a simple picture: it measures the link between a long list of numbers and a two-part 'yes or no' list, so the name helps you remember it shows the relationship between a variable with many values and a variable with just two choices.
