The applet shows the relationships among these distributions well. In order to fully appreciate this, students must be aware of the relationships to begin with.

Though this applet does provide a good display of the three distributions (binomial, poisson, and normal) on the same graph, the set-up is a bit misleading. Since the normal distribution shifts as the value of 'p' is altered, the user may think that 'p' is a parameter associated with a normal distribution.

This is a very useful toos for Elementary Statistics class because I can do simulation by changing the value of n and p. The same data can present different pictures. It is amazing.
