| APPLET | SOURCE | DESCRIPTION |
|
| p-value applet | Molina, accessed from J. Berger website | Demonstrates that common interpretations of p-values can be very misleading. Simulates data based on user specified inputs to show that the proportion of times that the null hypothesis is true when the p-value is in a specified range is much higher than alpha levels. more |
| P-Value of a Test of Significance | W.H. Freeman & Co. | Generates samples and shows sample mean and p-value on a graph as users vary hypotheses, sample size, standard deviation and true population mean. more |
| One sample hypothesis test | Java Applets for the Visualization of Statistical Concepts (VESTAC) | Generates a specified number of samples (shown visually) to illustrate the effects on the p-value of the test for a mean as users vary the hypotheses about a mean as well as the sample size, variance, significance level and true population mean. more

| Mean Test Experiment | Virtual Laboratories in Probability and Statistics (Siegrist, Duehring) | Simulates data for 1- or 2-tailed hypothesis tests for one mean, outputs for each run the sample statistic, test statistic, rejection indicator, and percentage of time hypothesis is rejected compared to theoretical, users can vary population distribution and parameters, test values, sample sizes, and significance levels, uses either Z or T as specified. NOTE: xhtml files may not run in all browsers. more |
| Hypothesis Testing Applet | WISE (Web Interface for Statistics Education) | Draws and shows samples of specified size from a normal population with user-adjusted parameters, calculates test statistics and p-values for a test for one mean, allows user to test against several different alternative hypotheses to see effects on p-values. See also http://opl.apa.org/TeacherTour/Power_Applet_Demo_Guide_060815.pdf for a demonstration guide for the applet. more |
| Proportion Test Experiement | Virtual Laboratories in Probability and Statistics (Siegrist, Duehring) | Simulates data for 1- or 2-tailed hypothesis tests for one proportion, outputs for each run the sample statistic, test statistic, rejection indicator, and percentage of time hypothesis is rejected compared to theoretical, users can vary population parameters, test values, sample sizes, and significance levels. NOTE: xhtml files may not run in all browsers. more |
| Proportions | Java Demos for Probability and Statistics (Stanton) | Simulates multiple trials of a test for a proportion, user sets hypothesized population proportion and actual value used to simulate the data, the alternative hypothesis and the significance level, displays visually sample data, sample proportion, and rejection region. more |
| Variance Test Experiment | Virtual Laboratories in Probability and Statistics (Siegrist, Duehring) | Simulates data for 1- or 2-tailed hypothesis tests for one variance, outputs for each run the sample statistic, test statistic, rejection indicator, and percentage of time hypothesis is rejected compared to theoretical, users can vary population distribution and parameters, test values, sample sizes, and significance levels.
