Question

Quizplus · Accepted Answer

The coefficient of determination is a measure of effect size that represents the proportion of variance in the dependent variable that can be explained by the independent variable(s). It is mathematically equivalent to eta-squared, which is used in ANOVA. The coefficient of determination is equal to the correlation coefficient squared, which indicates the strength of the relationship between two variables. Therefore, all of the options are correct.
