AB - 19] Limitations in Applicability of Contingency Coefficient 367 A SECOND CATEGORY OF LIMITATIONS IN THE APPLICABILITY OF THE CONTINGENCY COEFFICIENT By J. ARTHUR HARRIS AND CHI Trr, University of Minnesota Pearson in his fundamental paper on the theory of contingency 1 indicated clearly the difficulties of comparing coefficients of association, correlation and contingency. He then wrote (p. 22): "The degree of approach of both C and C to the correlation must be studied for each 1 2 special class of cases, and only when this has been done will their use be really legitimate and effective." This was written twenty-five years ago, but notwithstanding various subsequent contributions by Pearson himself, much remains to be done in the study of the special classes of cases to which it may seem desirable to apply contingency methods. This is unfortunate because of the fact that the contingency coeffi­ cient is the most general measure of the relationship between two variables. The contingency coefficient is independent of the nature of the variables (whether quantitatively measurable or only describ­ able in categories), of the form of the frequency distribution, of the order of arrangement of the classes, and of the nature of the regression
