| APPLET | SOURCE | DESCRIPTION |
|
| Sampling Distribution of the Mean applet | WISE (Web Interface for Statistics Education) | Generates samples and shows population and sampling distribution of the mean for one of 4 possible populations and various sample sizes. See http://wise.cgu.edu/sdmmod/index.asp for a tutorial on using this applet. more |
| Sampling Distribution of the Mean Illustrated | Psychological Statistics at Missouri State Univ. (Stockburger) | Generates samples of specified size from one of 4 possible populations and graphically compares sampling distribution of the mean to the population. more |
| The Sampling Distribution of the Sample Mean / Central Limit Theorem | Dept. of Statistics, Univ. of Auckland, (Regan) | Simulates and shows graphical display and statistics for the sample, sampling distribution of the mean, median, variance, standard deviation, range or MAD for one of several possible populations, which can be altered, and various sample sizes and number of samples. Can also be accessed through SOCR or RVLS. See http://serc.carleton.edu/sp/cause/interactive/examples/13785.html for an activity using this applet. more |
| Central Limit Theorem | Univ. of Michigan-Dearborn, Economics | Demonstrates CLT by showing general population and sampling distribution of the mean for samples of size 2, 10, 30, and 100. more |
| Central Limit Theorem | W.H. Freeman & Company | Demonstrates how the shape of distributions of the mean of samples from an exponential distribution will approach a normal as the sample size increases. more |
| Central Limit Theorem | Wolfram Demonstrations Project | For several different samples, shows how distribution of sample mean changes as sample size increases. Requires download of Mathematica player and demo itself, good for classroom demonstration. more |
| Sample size effect on sample mean | Applets for the Cybergnostics project (West) | Generates samples of size 1 through 25 from a population to observe that while the mean of the sample means stays constant, the standard deviation of the sample means decreases as n increases. more |
| Sampling | SABLE: Statistics Activity-Based Learning Environment | Users attempt to build samples with a given amount of error to observe size of sample needed is larger for smaller error margins, students simulate samples of different size and observe errors and distribution to illustrate CLT, also includes stratified sampling activity. more |
