Exploring “What’s Typical?” Using Probability
Technology: TI-84 Plus family, TI-Nspire™ Technology
Speakers: Tracy Watson, Don Worcester
Many statistical investigations revolve around the question, “What’s typical?”
Probability provides a way to measure how “typical” something is and provides a language for describing uncertainty. Sample space and event are “duals” of population and statistic. Formulas for combining random variables explain inference standard error formulas for differences.
- Relate key concepts of probability to corresponding concepts in statistics
- Examine probability as a long-run measurement
- Illustrate how technology can be used to determine probabilities through direct calculation and through simulations
- Investigate calculation and interpretation of expected values
- Discuss measures for random variables formed by combining other random variables
- Relate each of these concepts to the AP* testing experience
Both TI-84 Plus and TI-Nspire™ technology are used.Play Webinar Download Associated Documents
