D) any level of measurement

Question

Quizplus · Accepted Answer

Phi and Cramer's V are appropriate measures of association for variables measured at the nominal level. They are calculated based on the frequency of observations in each category, and do not take into account the magnitude of the differences between categories (as would be necessary for interval-ratio level variables) or the ordering of the categories (as would be necessary for ordinal level variables). Therefore, they are most effective for nominal level variables, where the categories are simply labels with no inherent order or magnitude.
