Students learn about Type I and Type II errors. Then, for a given scenario, they calculate the probabilities of errors and the power of the test.

Key Steps

  • Image

    Students are introduced to Type I and Type II errors, and the concept of power. Self-check questions allow students to test their understanding of the concepts.

    In the second part of the activity, students calculate Type I and Type II errors and the power of the test using a given scenario. They are led through steps of finding a z-interval and standardizing values to find the probability of type II errors.
