The following scatterplot examines the potential association between years of education and weekly salary. The data was obtained from the Combaro dataset on the student website (Combaro.xls). Write short descriptions about what you would expect to see in the graph and what you actually see. In examining both descriptions, estimate the correlation coefficient in each case. Using the Combaro dataset, calculate the correlation coefficient. What does your analysis suggest about the years of education an employee has completed and the amount they are paid?
