Observations on the K Measure of Association

Berry and his associates presented a new nominal level measure of association K, that is useful for statistically evaluating research hypotheses applied to a 2 × 2 contingency table. We have added shortcut computational equations for K along with an alternative interpretation. Limitations of K are noted, including specified logical relations being in part a function of the marginal configuration and the lack of the property of invariance. Two new coefficients are added, one of which expands K to larger tables and to a wider scope of measures and another that norms K by its expected value
