Property of correlation coefficient
WebA correlation coefficient is a numerical measure of some type of correlation, meaning a statistical relationship between two variables. [a] The variables may be two columns of a given data set of observations, often called a sample, or two components of a multivariate random variable with a known distribution.

It even satisfies the scalar portion of the linearity property [f(aX,Y)=af(X,Y)]. On a case-by-case basis, if we can conjure up a useful or believable definition of vector addition for a data set, then correlation would meet all the requirements an inner product!
