Cramer's statistic is the appropriate index for measuring the strength of the relationship between two variables in a contingency table when both variables have three levels. The phi coefficient and Pearson correlation are appropriate when both variables have two levels while the fourfold point correlation coefficient is not a valid measure of association for contingency tables with three levels.
