Morphology
The meaning is directly derivable from combining 'correlation' (a measure of relationship) with 'coefficient' (a numeric factor), so a learner who knows both constituents can infer it denotes a numeric measure of the relationship between variables. Although technical, the noun+noun composition is compositional and follows common cross-linguistic patterns, making it morphologically transparent.
Etymology
The term correlation coefficient combines correlation (how two things move together) and coefficient (a single number that measures it). Imagine two dancers: if they move exactly together the number is +1, if they move opposite the number is -1, and if they move without a pattern the number is about 0, so the term means 'a number that shows the strength and direction of a relationship'.
