Unit 8 - Section 4.3

1. Fill in the blank. The R, measures the proportion of total variation in the response variable that is explained by the least squares regression line. The (1) R", measures the proportion of total variation in the response variable that is explained by the least squares regression line. (1) O total deviation, DO residual coefficient of determination, O linear correlation coefficient, . Fill in the blanks. Total deviation = deviation + deviation Choose the correct answer below. O A. Total deviation = unexplained deviation + explained deviation O B. Total deviation = response deviation + explanatory deviation O C. Total deviation = positively associated deviation + negatively associated deviation O D. Total deviation = predicted deviation + observed deviation Match the coefficient of determination to the scatter diagram. The scales on the x-axis and y-axis are the same for each scatter diagram. (a) R" = 0.90, (b) R
