Application of Power

Activity Overview

Students use the concept of power to explore how the probability of rejecting the null hypothesis, when it is false, plays a role in a real-world scenario.

Key Steps

    Students use the concept of power to explore how the probability of rejecting the null hypothesis, when it is false, plays a role in a real-world scenario.

    They will first answer a few questions about what power represents related to the hypotheses and what it represents related to the scenario.

    Then, by manipulating the sample size, the true population mean, and alpha, students recognize how each of these decreases or increases the value of power. Students will determine what impact each variable has on the real-world scenario.
