WebSep 16, 2024 · Phi and Cramer’s V provide a test of statistical significance and also provide information about the strength of the association between two categorical variables. They can be used as measures of the effect size. If one has a 2 x 2 cross-tabulation, phi is the appropriate statistic. For larger cross-tabs, Cramer’s V is used. WebCramer's V. A problem with both Cramer's V and phi is that values between 0.00 and 1.00 can be interpreted only as an index of the relative strength of the association.

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. WebIt is interpreted as a measure of the relative (strength) of an association between two variables. The coefficient ranges from 0 to 1 (perfect association). In practice, you may find that a Cramer's V of .10 provides a good minimum threshold for suggesting there is a substantive relationship between two variables.
