Quizplus · Accepted Answer

The product moment correlation is a commonly used statistic to summarize the strength of association between two metric variables. It measures the degree to which the variables are linearly related to each other, ranging from -1 (perfect negative correlation) to 1 (perfect positive correlation), with 0 indicating no correlation. ANOVA, partial correlation coefficient, and multiple regression analysis are all used to analyze relationships between variables, but they are not specifically designed to summarize the strength of association between two metric variables.
