c. Construct a scatter diagram graph that shows Goodmans and Landry returns on the vertical axis and the Market Indexs returns on the horizontal axis. It is easiest to make scatter diagrams with a data set that has the X-axis variable in the left column, so we reformat the returns data calculated above and show it just below. Year Index Goodman Landry 2016 0.0% 0.0% 0.0% 2015 0.0% 0.0% 0.0% 2014 0.0% 0.0% 0.0% 2013 0.0% 0.0% 0.0% 2012 0.0% 0.0% 0.0% To make the graph, we first selected the range with the returns and the column heads, then clicked the chart wizard, then choose the scatter diagram without connected lines. That gave us the data points. We then used the drawing toolbar to make free-hand ("by eye") regression lines, and changed the lines color and weights to match the dots.
