An applet that allows users to see plots with a specified correlation; to compare plots, varying the correlation and standard deviations of the variables; and to play games to test ability to estimate the correlation coefficient for a given plot.
This applet, while not intended to teach the concept of correlation, does a good job showing the meaning of the strength of the correlation. Running the animation allows the student to see what happens to the scatter plot as the correlation moves away from a perfect positive correlation. In an online envirnoment this applet will allow an instructor to pose a questions relative to the applet on the discussion board and then have students work with the applet to answer the questions.
