The Probability/Statistics Object Library
The applets in our library are intended to illustrate concepts and techniques in probability and statistics in an interactive, dynamic way. You can download an applet, "drop" it into a web page (details on page 4), and then add other elements of your choice, such as expository text, data sets, and graphics. The PSOL currently contains approximately 60 applets that fall into two basic categories:
In the next three sections we will consider a particular representative applet, the Dice Experiment, in some detail. My purpose is not to discuss the underlying mathematics, but rather the issues of reuse and adaptability.
