Web-based exercise. The best way to develop some feeling for how a regression line fits the points on a scatterplot is to use an applet that allows you to plot and move data points and watch the least-squares line move as the points change. Go to the Statistics: Concepts and Controversies Web site, www.whfreeman.com/scc7e, and look at the Correlation and Regression applet. Click in the “Show least-squares line” box to see the regression line. Where should one place or move points to in order to have the largest effect on the least-squares line?
