Hi Bruce, correlation ratio (eta) is different from correlation coefficient (rho). While correlation coefficient captures only a linear relationship btw variables, correlation ratio captures both linear and non-linear relationships. It is the defined as the ratio of the variance between arrays to the total variance.
