AP STATISTICS “Do Cell Phones Distract Drivers?”

RESULTS OF CELL PHONE STUDY

WHAT ARE THE POSSIBILITIES? Either the cell phones make a difference, and are a real cause for driver distraction OR There is NO difference between cell phones and passengers, and these study results were due to the random assignment of the drivers to the treatment groups.

SIMULATION RESULTS Number of drivers who miss exit in cell phone group in each trial… RECALL – these results assume that the cell phone makes no difference in missing the exit!

COMPUTER SIMULATION RESULTS

4 BROAD CONCEPTUAL THEMES Exploring Data: Describing patterns and departures from patterns Sampling and Experimentation: Planning and conducting a study Anticipating Patterns: Exploring random phenomena using probability and experimentation Statistical Inference: Estimating population parameters and testing hypotheses
