Categorizing Statistics Problems

On this webpage, you can practice identifying situations where various hypothesis tests and confidence intervals are used. Press begin to select the items that would like to practice identifying. You will be presented with a statistics problem, and your goal is to identify what inference procedure would be used in the situation presented.

This program was adapted by Skylar Smith as an AP Statistics student at Fishers High School. This program is originally from a webpage by Larry Green, a member of the faculty of Lake Tahoe Community College.
