| APPLET | SOURCE | DESCRIPTION |
|
| Normal Demonstration | Applets for the Cybergnostics project (West) | Shows how the normal curve changes as mean and standard deviation are varied with sliders. more
 |
| Bell Curves | Wolfram Demonstrations Project | Shows change in location and shape of a normal as mean and standard deviation are varied. Requires download of Mathematica player and demo itself, good for classroom demonstration. more |
| Area of a Normal Distribution | Wolfram Demonstrations Project | Shows a normal alongside the standard normal with z-scores and associated x values and left and right tailed probabilities shown, can vary mean, standard deviation and z-scores with a slider and view changes in both curves. Requires download of Mathematica player and demo itself, good for classroom demonstration. more |
| Normal Distribution | Interactive Statistics (Lind, Marchal, Wathen) | Displays the change in the curve and calculates an upper tail probability for an x value as mean and standard deviation are varied. more |
| Normal Probability Calculator | Rossman/Chance Applet Collection | Compares graphically two user-specified normals, computes z-scores for both and calculates interior or two tailed probabilities for any values. more
|
| The Random Variable Experiment | Virtual Laboratories in Probability and Statistics (Siegrist, Duehring) | Simulates normal distribution (or other continuous distributions) with specified mean and standard deviation (values limited) and compares mean and standard deviation of data to theoretical. NOTE: xhtml files may not run in all browsers. more |
| Quantile applet | Virtual Laboratories in Probability and Statistics (Siegrist, Duehring) | Use like a statistical table (with graphical display) for several continuous distributions, calculates left tail probabilities from given values or vise versa.
