A researcher computes a 4 * 6 chi-square test for independence with a sample of 120 participants,with $\chi$² = 14.79.What is the effect size for this result? A) .04 B) .20 C) .12 D) .35

Question

To compute the effect size, we need to use the formula for Cramer's V, which is the square root of the chi-square statistic divided by the sample size multiplied by the minimum of the number of rows minus 1 or the number of columns minus 1. In this case, the square root of 14.79 divided by 120 multiplied by the minimum of 3 minus 1 or 10 minus 1 is approximately .20. Therefore, the effect size is .20, which corresponds to choice B.
