| APPLET | SOURCE | DESCRIPTION |
|
| Practice True or False Questions Involving Elementary Statistics | Larry Green's Applet Page | Dozens of true/false questions with instant feedback covering descriptive statistics and sampling techniques, graphical displays, probability concepts, confidence intervals and Z, hypothesis testing, regression analysis, chi-square tests and ANOVA. more |
| The Reasoning of a Statistical Test | W.H. Freeman & Co. | Illustrates concepts of hypothesis tests and making decisions based on sample data by generating samples of basketball players shooting free throws (with graphics) and allowing user to try to ascertain veracity of claims about true free throw percentages. more |
| Decisions Based on P-Values and Significance Levels | Wolfram Demonstrations Project | Illustrates relationship between alpha and p-value by showing how changes in values affect rejection decision. Requires download of Mathematica Player as well as demo itself, good for classroom demonstration. more |
| Hypothesis Testing | SABLE (Statistics Activity Based Learning Environment) | Expository information on hypothesis testing, along with activities to reinforce concepts, including: making decisions about populations based on sample data, observing sampling distributions from a small finite population and changing sample sizes and observing effects, determining statistical significance and rejection decisions based on summary data and p-values for various examples. more
  |
| T Distributions | SABLE (Statistics Activity Based Learning Environment) | Expository information on T distributions, along with activities to reinforce concepts, including comparing t distributions to the standard normal, finding probabilities and critical values, and making rejection decisions for both single population and two population tests. more |
| Hypothesis Testing Applet | Kerbaugh | Walks user through a hypothesis test step by step, from specifying hypotheses and significance level to entering data or sample statistics and selecting the correct rejection criteria and observing p-value and results of the test. more |
| Hypothesis Tests for the Population Mean | Economics Dept., Univ. of Michigan-Dearborn | Walks student through process of testing a hypothesis about a mean using both the critical value and p-value approach, user can change sample statistics and alpha but can only test that the mean is equal to 10. Also includes explanations. more |
| Hypothesis Tests about a Population Mean | Wolfram Demonstrations Project | For either one or two tailed tests, allows user to adjust sample size, hypothesized mean, population variance and significance level to see the effect on the rejection region, p-value and decision. Requires download of Mathematica Player as well as demo itself, good for classroom demonstration. more |
