Normal approximation to the poisson distribution
Poisson and Normal Distribution
The normal distribution is the backbone of statistics. This distributions often provides a reasonable approximation to the data. Moreover, the central limit theorem states that to the distribution of a statistic such as the mean of values from non normal distribution is normally distributed. This applet draws the Poisson distribution together with the normal distribution. You can specify the rate and the number of trials (n) in the dialog boxes. By changing these parameters, the shape and location of the distribution changes. This Applet gives you an opportunity to study how the approximation to the normal distribution changes when you alter the parameters of the distribution.Other things to do:
