Quizplus · Accepted Answer

The coefficient of determination, often denoted as R^2, measures the proportion of the variance in the dependent variable that is predictable from the independent variable(s). It essentially tells us how much variance in one variable is shared with another, making option A correct. It does not directly allow for cause-and-effect statements, prediction of specific scores, or determination of regression coefficients without further calculation.
