Rank statisticsof actual variatesplay an important role in university undergraduate nonparametric statistics courses. This article derives explicit expressions of the correlation coefficients between Xi and Rj for not only i = j but also, forcontinuous variableswith a distribution functionof X and: (a)for any i, revealing that the correlation can be as close to one as expected, while may also unexpectedly decrease approaching zero for other distributions of X; (b)for any, inferring a negligible negative association with ranks from other data; (c) the partial correlation coefficient between Xi and Ri on Xj for anyequals ρ(Xi,Ri)·Xj=ρXi,Ri/1−ρXj,Ri2∈(ρXi,Ri,n−1n2−2], invariably exceeding. Implications of the results necessitate more relevant interpretation of ranks in sharing information of data.
