Question

Quizplus · Accepted Answer

The correlation ratio is appropriate for determining the degree of relationship between two variables when the relationship is markedly nonlinear, as it can measure the extent of association between a nominal-level variable and a ratio-level variable, accommodating nonlinear relationships.
