| APPLET | SOURCE | DESCRIPTION |
|
| Binomial Distribution | Hooper, Clarkson Univ. | Simulates several discrete (including binomial) and continuous distributions (including normal, t, F and chi-square - see "Several Distributions") as well as sampling distribution of the mean, shows visually theoretical and observed distribution and parameters. 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 |
| T demonstration | Applets for the Cybergnostics project (West) | Illustrates how shape of t distribution changes as df increase and compares to normal. more |
| StudentT | Seeing Statistics (McClelland) | Illustrates how shape of t distribution changes as df increase and compares distribution and 2-tailed critical values for 5% to those of normal. more |
| Student's t-Distribution | Wolfram Demonstrations Project | Illustrates how shape of t distribution changes as df increase and compares to normal, indicating the percent overlap between the distributions. Requires download of Mathematica player and demo itself, good for classroom demonstration. more |
| T probabilities applet | Statistical Java (Dorai-Raj, Anderson-Cook, Robinson) | Computes area to left or right of a value or between two values on a t with specified degrees of freedom, compares to probability on a normal, and displays both visually. more |
| Statistics Web, Normal vs. t-dist | Industrial Engineering Dept., South Dakota School of Mines & Technology | Computes critical values of a t distribution and compares to normal critical value for a specified alpha/2 value. more |
| T calculator -- Graphics Version (T distribution calculator) | Applets for the Cybergnostics project (West) | Computes area to left or right of a value of a t with specified degrees of freedom or computes critical value from specified probability and displays it visually. more |
