Effect Sizes: Why Significance Alone is Not Enough
WebThey are used as measures of effect size for tests of association for nominal variables. The 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.
