Morphology
coefficient + of + correlation
The phrase is compositionally built from 'coefficient' (a measuring constant) and 'correlation' (the relationship/association between variables), so its meaning as a numeric measure of correlation is directly derivable from the parts. The noun + of + noun construction is a standard, cross-linguistic compositional pattern, making the expression transparent to learners who know the constituent words.
Etymology
Coefficient of correlation comes from the idea that a number, the coefficient, shows how much two things, the correlation, 'move together'. Imagine two dancers: if they move the same way the number is close to +1, if they move the opposite way it is close to -1, and if they do not match it is near zero. So the term means a number that tells how strongly two measurements change together.
