Create a scatterplot of Predicted Grades with Grades, along with a regression line. Pick a data point in the raw data and note the actual value for Grades, Predicted Grades, and the Residual. Is the residual equal to Grades minus Predicted Grades? Now find the same data point on the scatterplot and mark the value on the graph for that person’s Grades and Predicted Grades. Show graphically the residual.
