This activity enables students to learn about confidence intervals and hypothesis tests for a population mean. It focuses on the t-distribution, the assumptions for using it, and graphical displays. ...

This applet allows users to play several probability games like Monty Hall, Gambler's Ruin, Galton's Board, etc. Select a game from the drop down menu and click "About" to read its background. ...

This applet simulates rolling dice and displays the outcomes in a histogram. Students can choose to roll 1, 2, 6, or 9 dice either 1, 10, 20, or 100 times. The outcome studied is the sum of the...

Share with your students why the presence of an outlier affects which measure of central tendency to report. Feel free to modify this Powerpoint presentation to fit the needs of your students. ...

This tutorial is intended to teach students how power in a one-sample Z-test is influenced by effect size, variability (population standard deviation), sample size, and significance level. WISE Power...

This applet simulates drawing samples of Reese?s Pieces from a candy machine. Users set the sample size, number of samples, and theta, the population proportion of orange pieces. The applet keeps...

A collection of applets addressing data analysis, sampling distribution simulations, and probability and inference. Some can be used individually, though others require context from the textbook.

This applet simulates drawing samples from a binomial distribution. Users set the population proportion of success (pi), sample size (n), and number of samples. By clicking ?Draw Samples,? the applet...

This applet generates confidence intervals for means or proportions. The options for confidence intervals for means include ?z with sigma,? ?z with s,? or ?t.? The options for confidence intervals...

This applet is designed to help students visualize p-value by allowing them to set null and alternate hypotheses, population parameters, and sample statistics. It accompanies "Practice of Business...
