| APPLET | SOURCE | DESCRIPTION |
|
| Hypothesis Tests for a Proportion | Prentice-Hall applets (West) | Generates samples to illustrate how test statistics, p-values, actual Type I error rates and power vary for a test for the proportion based on user-specified sample size, population shape and parameters, and null proportion. more |
| Power Simulation | Rossman/Chance Applet Collection | Simulates samples for tests for the proportion and calculates and shows graphically the observed level of significance and approximate power based on specified hypothesized and alternative values of pi, sample size, and significance level. more |
| Several under "Calculation of Hypothesis Tests" and "Power of Hypothesis Tests" | Dept. of Statistics, Texas A&M Univ. | Several applets for one or two means and one or two variances, each allows user to specify distribution for population, sample size, significance level, and (for power applets) alternative hypothesis and to generate samples and tally the proportion of times the null is rejected, population, samples and type I error are shown graphically, includes some explanatory information on hypothesis tests. more |
