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