Tool for Teaching Regression
Professor Charles Stanton of California State University, San Bernardino has put up a nifty tool that can help in the understanding of linear regression. The java applet allows you to place regression points on a Cartesian plane. Once you put down two points, the applet draws a regression line and gives you the equation for the line. As you add more and more points, the line and the equation update in real time. It’s fun to see how outliers can completely give false results. Check it out here.
