Welcome to WISE!

Updating Applets

We have been working hard updating our applets to canvases so that they no longer require Java. Our confidence interval creation tool has been redone, and is now available without Java. Check it out!

Java Notice:

With the most recent Java update, your security settings might block our applets from running. We are currently working on this issue. In the meantime, if you wish to unblock our applets, you must go through a few steps in the Java Control Panel:
  1. Go to the Java Control Panel (On Windows Click Start and then type Configure Java)
  2. Click on the Security tab
  3. Click on the Edit Site List button
  4. Click the Add button
  5. Type http://wise1.cgu.edu
  6. Click the Add button again
  7. Click Continue and OK on the security window dialogue box
  8. Restart your computer

You can read more about the issue at Java.com

Our goal is to provide students and teachers of statistics easy access to a wide range of resources that are freely available on the Internet. We invite you to explore our website and enjoy many wonderful statistics materials from around the world.

A special feature of WISE is the sequence of interactive tutorials on key statistical concepts (sampling distributions, the central limit theorem, hypothesis testing, and statistical power). The tutorials use dynamic applets that allow the user to explore relationships on their own. Guided exercises are designed to help the learner to take full advantage of the applets to gain a deeper understanding of the concepts and logic that underlie much of inferential statistics.

We invite your feedback on WISE. If you find any errors, if you have suggestions for additions or improvement, or if you find this site useful, we would love to hear from you. Drop us an email at

NOTE: If WISE applets are not loading properly, download and install the latest version of the free Java Runtime Environment. For more information, refer to our technical support page.

Confidence Interval Game

Test your ability to estimate p values from confidence intervals with the WISE Confidence Interval Game! Do you have what it takes to get a perfect score?

A Guide can be downloaded for this game.

Bootstrapping Applet

The WISE Bootstrapping Applet can be used to demonstrate bootstrapping by creating a confidence interval for a population mean or median. The user can manipulate the population distribution, sample size, and number of resamples. An associated guide gives suggestions for teaching bootstrapping.
