Quizplus · Accepted Answer

The product moment coefficient, also known as Pearson's correlation coefficient, is the statistic that summarizes the strength of association between two metric variables. Regression analysis can also be used to analyze the relationship between two variables, but it involves predicting one variable based on the values of the other. Partial correlation coefficient is used to quantify the association between two variables while controlling for the effects of one or more additional variables. ANOVA is used to compare the means of two or more groups. Gamma is a measure of association between two ordinal variables.
