University of Colorado: Normal Probabilities Applet #2
This Applet allows the user to grab and drag the ends of the included region below the standard normal curve to the appropriate places needed. The user directly experiences the connection between the shaded area under the curve and the...
California State University
Cal State San Bernardino: Central Limit Theorem Applet
In this applet, rolling of dice is studied. The number that lands face "up" on the die is graphed as the die is rolled repeatedly. The user begins to see, with increased accuracy, the standard normal curve appearing as the graph.
