Interpreting Correlation Coefficients - Statistics By Jim

WebInterpretation: In 2-b-2 tables, phi can be interpreted as symmetric percent difference, measuring the percent of concentration of cases on the diagonal. Also in 2-by-2 tables, phi is identical to the correlation coefficient. In larger tables, where phi may be greater than 1.0, there is no simple intuitive interpretation, which is a reason why phi is often used only for … WebPhi_K is a practical correlation constant that works consistently between categorical, ordinal and interval variables.
