Exploring “What’s Typical?” Using Sampling Distributions and Simulation

Many statistical investigations revolve around the question, “What’s typical?” This is especially true in formal inference. Reference distributions provide the basis for addressing that question.

Presenters will:

• Relate the need for reference distributions to the logic of hypothesis tests and confidence intervals
• Explore both theoretical and simulation-based reference distributions based on AP* items
• Show how the functionality of TI technology can enhance the understanding of reference distributions

Both TI-84 Plus and TI-Nspire™ technology are used.
