Which of the following statements pertaining to the contingency coefficient is FALSE?
A) The contingency coefficient is directly related to the chi-square test.
B) Its upper value limit is determined by the number of categories in a problem.
C) Some of the difficulties encountered in interpreting the contingency coefficient are overcome by squaring the coefficient, thereby obtaining the proportion of variance in the criterion variable explained by the predictor variable.
D) The contingency coefficient as a measure of association is difficult to interpret purely by examining the calculated value.
E) The contingency coefficient provides a measure of the strength of the association between the variables.

The contingency coefficient is indeed related to the chi-square test and provides a measure of association between variables, but squaring the contingency coefficient does not yield the proportion of variance in the criterion variable explained by the predictor variable. This description applies to the coefficient of determination (R^2) in regression analysis, not to the contingency coefficient.
