The formula for Cramer's phi statistic is: A)the square root of [χ²/N (df smaller)] B)the square root of [χ²/N (df larger)] C)df smaller multiplied by N-1 D)χ²/ df smaller

Question

Quizplus · Accepted Answer

Cramer's phi statistic is calculated as the square root of the chi-square statistic divided by the sample size and the smaller of either the number of rows minus one or the number of columns minus one, which is not represented by any of the provided formulas exactly. However, choice A, despite its unconventional notation, suggests a formula involving the square root and division by N, which aligns more closely with the concept of Cramer's phi, albeit the notation is incorrect or unclear.
