The coefficient of determination r2 is the ratio of which two types of variations? What does r2 measure? What does 1-r measure? The coeffcient of determination is the ratio of the explained variation to the total variation. OA. The coefficient of determination is the ratio of the OB. The coefficient of determination is the ratio of the total variation to the explained variation. explained variation to the total variation. OC. The coefficient of determination is the ratio of the OD. The coefficient of determination is the ratio of the total variation to the unexplained variation. unexplained variation to the total variation. Choose the correct answer below. A. The coefficient of determination is a measure of OB. The coefficient of determination is the percent of how closely two variables vary together. the variation that is unexplained. C. The coefficient of determination is the percent of OD. variation of y that is explained by the relationship between x and y. The coefficient of determination is the percent of the predicted values that equal the actual data values. Choose the correct answer below. A. The value 1-r2 is the percent of the predicted values that equal the actual data values. OB. The value 1-r2 is the percent of the variation that is unexplained. OC. The value 1-r2 is the percent of variation of y that is explained by the relationship between x and y. OD. The value 1-r2 is a measure of how closely two variables vary together.
