Quizplus · Accepted Answer

The correlation coefficient (r) is a measure of the strength and direction of the linear relationship between two variables. It is also considered an effect size indicator because it provides an estimate of the magnitude of the relationship between the two variables. F and t statistics are measures of the significance of the difference between groups or the relationship between variables, but they do not directly provide an estimate of the effect size. p-value is also not an effect size indicator, it is a measure of the probability of obtaining the observed results by chance.
