Probability and Quantile Applets (by Balasubramanian Narasimhan)
The first applet on this page allows the user to find areas within any region under the normal density curve. The second applet can be used to find the z-score corresponding to any given probability value for a normal cumulative density function.

Student's T-distribution (by Balasubramanian Narasimhan)
This page provides a Java applet that illustrates the relationship between a t-distribution and a standard normal distribution for alternative degrees of freedom. You can use this applet to see how quickly the t-distribution converges to a standard normal distribution as the size of a sample rises. On this page you can also learn how a brewing company was responsible for providing us with the use of t-statistics.
