The experiment simulates a value of a random variable with a specified distribution. The value is recorded on each update. The following distributions can be chosen from the list box:
distributions can be chosen from the list box. In each case, the parameters of the distribution can be varied with scroll bars. You may have to undock the toolbar to make all of the controls visible. The density and moments of the distribution are shown in blue in the graph, and the moments are given in the second table. On each update, the empirical density and moments are shown in red in the graph, and the empirical moments are recorded in the second table.
This applet illustrates the distributions in the list above and the topics and concepts in the list below. Click on the links to learn more about the mathematical theory.

To add the applet to your web page, insert the following in the html file, at the point where you want the applet to appear:
<applet code="edu.uah.math.experiments.RandomVariableExperiment.class"
archive="RandomVariableExperiment.jar" width="600" height="450"></applet>
The jar file and the html file must be in the same folder.
This width and height dimensions are simply suggestions and can be varied. Generally, components such as graphs and tables expand and contract proportionally, while components such as buttons, scrollbars, dice, and coins are fixed in size.
