Morphology
rank-order + correlation + coefficient
The phrase is fully compositional: 'rank-order' specifies the type of ordering, 'correlation' names the relationship being measured, and 'coefficient' signals a numeric measure — together yielding a coefficient that measures the correlation between ranks. Although the term is technical, the internal structure follows regular English modifier + noun + noun patterns, so a learner who knows the constituent meanings can infer the MWE meaning.
Etymology
The term rank-order correlation coefficient comes from the simple image of two lists where each item has a rank in an order. It is a single number that shows how well the two 'orders' match: if the same items are near the top in both lists the coefficient is high, and if the lists are different the coefficient is low.
