An example in R, as sample size goes up, p-value gets smaller but Cramer's V stays the same:

Did you know?
WebThe statistics phi and Cramér’s V are commonly used. Cramér’s V varies from 0 to 1, with a 1 indicting a perfect association. phi varies from –1 to 1, with –1 and 1 indicating perfect associations. phi is available only for 2 x 2 tables. Cohen’s w is similar to Cramér’s V in use, but it’s upper value is not limited to 1. WebWhen rows = columns = 2, Cramer's V is the same as the phi coefficient. As well, the phi coefficient is the same as the Pearson correlation between the two nominal variables (e.g., as if they...
WebCramér’s V is an effect size measurement for the chi-square test of independence. It measures how strongly two categorical fields are associated. The effect size is calculated in the following manner: Determine which field has the fewest number of categories. Subtract 1 from the number of categories in this field. 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.
WebTABLE 1: phi = -.667, Cramer's V = .667 TABLE 2: phi = .667, Cramer's V = .667 All p-values = .001 Remember that Phi = Pearson's r on a pair of dichotomies. So negative values must be... WebCramer’s V, Tschuprow’s T and Pearson’s Contingency Coefficient, all measure the degree to which two nominal or ordinal variables are related, or the level of their association. This differs from correlation, although many often mistakenly consider them equivalent.
In statistics, Cramér's V (sometimes referred to as Cramér's phi and denoted as φc) is a measure of association between two nominal variables, giving a value between 0 and +1 (inclusive). It is based on Pearson's chi-squared statistic and was published by Harald Cramér in 1946. Zobraziť viac φc is the intercorrelation of two discrete variables and may be used with variables having two or more levels. φc is a symmetrical measure: it does not matter which variable we place in the columns and which in the … Zobraziť viac Cramér's V can be a heavily biased estimator of its population counterpart and will tend to overestimate the strength of association.
