Quizplus · Accepted Answer

Pearson's r is the most appropriate measure of association for measuring the strength of the linear relationship between two continuous variables, such as income and education. The slope (b) would only measure the strength of the linear relationship between income and education in a regression model, whereas gamma and chi square are typically used for measuring the strength of association between two categorical variables.
