Learn by Doing 1. Calculate each point's contribution to the part of the total variation explained by the regression model (i.e. the vertical distance between the least-squares regression line (the predicted value for the point) and the mean of the y-values). Report your answer to one decimal place. Part of total variation explained by the model for (1,3): Part of total variation explained by the model for (2,5): Part of total variation explained by the model for (3,6): Part of total variation explained by the model for (4,6): 2. What is the sum of the four point's contributions to the part of the total variation explained by the regression model? ? Next
Learn by Doing 1. Calculate each point's residual (i.e. the vertical distance between each point's observed value and the least-squares regression line (the predicted value for the point). Report your answer to one decimal place. Residual for (1,3): Residual for (2,5): Residual for (3,6): Residual for (4,6): 2. What is the sum of the residuals of the four points? Previous
