Online Simulation: Confidence Interval
This Java applet is designed to help students understand what is meant by a confidence interval around the mean and how the width of this interval depends on both sample size and confidence level.
The simulation and its associated questions can be used as either homework assignment or as an in-class activity for those classes with access to computers with Internet connection. It can also be used easily in courses that utilize a course management system. Students can work either in pairs or individually as they run the simulations and answer the questions.
