The Normal Distribution and Density

The Normal Distribution and Density

The user is be able to change the mean and the standard deviation using the sliders and see the density change graphically. The check buttons (68, 95, 99) will help one realize the appropriate percentages of the area under the curve. An example of this "68-95-99.7" rule follows. Overall this site, created by author Balasubramanian Narasimhan of Stanford University, is a good resource to help students better understand the concept of standard deviations.
