In any event, the RCC is applied to a setof ordinal rank no., with1 for the individual ranked in quality, or quantity and so on , to n for the individual ranked last in a group of n individual.

In any event, the RCC is applied to a setof ordinal rank no., with1 for the individual ranked in quality, or quantity and so on , to n for the individual ranked last in a group of n individual. RANK CORRELATION COEFFICIENT IS DEFINED AS :- R = 1 - 6?D²/N³- N Where r denotes RCC and D refers To the difference of the rank between paired items in to series.
