The product moment correlation,r²,is an index used to determine whether a linear,or straight-line,relationship exists between X and Y.It indicates the degree to which the variation in one variable,X,is related to the variation in another variable,Y.

Question

Quizplus · Accepted Answer

The product moment correlation is denoted by "r", not "r²". "r²" is the coefficient of determination, which indicates the proportion of variance in one variable that is predictable from the other variable.
