Activity Overview

Students learn about Type I and Type II errors. Then, for a given scenario, students will 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.
