(Similar to Pearson …

WebCramer's V is used as a measure of association between two nominal variables, or as an effect size for a chi-square test of association. For a 2 x 2 table, the absolute value of the phi statistic is the same as Cramer's V. Because V is always positive, if type="perc" , the confidence interval will never cross zero. WebCramer's V is an effect size from the 'correlation family' of effect sizes. Therefore, you could convert using the formula for converting r to d: Cohen's d = 2 r 1 − r 2. However, note that this ' d ' is quite different from the regular Cohen's d, which represents the difference between two means expressed in standard deviations.
