Normal Distribution


This applet illustrates the Normal distribution. There are two slider bars which allow changing the mean and variance parameters of the distribution. Note how changing the mean parameter shifts the density to one side or the other. This is known as a location parameter since it changes the location of the mean. The variance parameter is called a shape parameter as it changes the peakedness of the density.

Several statistics are shown for the distribution below the illustration of the density and distribution plots.
