correlation coefficient

n.

A measure of the interdependence of two random variables that ranges in value from -1 to +1, indicating perfect negative correlation at -1, absence of correlation at zero, and perfect positive correlation at +1. Also called coefficient of correlation.

correlation coefficient

n

(Statistics) statistics a statistic measuring the degree of correlation between two variables as by dividing their covariance by the square root of the product of their variances. The closer the correlation coefficient is to 1 or –1 the greater the correlation; if it is random, the coefficient is zero. See also Pearson's correlation coefficient, Spearman's rank-order coefficient
