How Likely …? Two-Way Tables and Chi-Squared Distributions

Technology: TI-84 Plus Family, TI-Nspire™ Technology
Speakers: Ray Barton, Landy Godbold

Many statistical investigations revolve around the question, “How likely could this event occur by chance?” Two-way tables, graphical representations and chi-squared distributions can help students answer this question in many contexts. TI technology can be a powerful tool to help students see and interact with these concepts.

In this webinar, presenters will:

  • Show how to create interactive two-way tables and their associated bar graphs
  • Use these interactive tables and graphs to help students understand conditional probabilities
  • Demonstrate technology tools that calculate probabilities involving chi-squared distributions
  • Discuss related AP* questions

Presenters will utilize both TI-84 Plus CE and TI-Nspire™ handheld devices during the webinar.
