The simulation displays a diagram with a generalized Gaussian normal distribution curve. The user can choose the mean and the standard deviation for the distribution as well as value(s) for the random variable. The simulation calculates the related z-value(s) and displays the area(s) left, right or between the chosen z-values. It also calculates the related probabilities.

The simulation is well suited to support teaching the basics of normal distributed variables. It frees the instructor from working with the normal distribution table and displays the related graph interactively. It can also used by students to confirm the values they have retrieved from a z-table for specific problems. Probabilities are calculated with only one digit behind the decimal point for two reasons. One is that the underlying algorithm is not precise enough. The other reason is that this application should not be used to answer homework questions.
