Quizplus · Accepted Answer

Correlation coefficients are used to measure the degree of association between two continuous variables measured at the ratio or interval level. Categorical variables (A and D) are better analyzed using t-tests or an F-ratio, while a correlation coefficient is not appropriate for variables measured at the nominal level (C).
