Meaning of Alpha

Activity Overview

• Students will recognize that the alpha value (significance level of a test) is the relative frequency for sample statistic values that lead to a "reject the null" conclusion, given that the null hypothesis is actually true.
• Students will recognize that a sample mean can lead to a "reject the null" or "fail to reject the null" depending on the alpha level.

Objectives

• Students will recognize that the alpha value (significance level of a test) is the relative frequency for sample statistic values that lead to a “reject the null” conclusion, given that the null hypothesis is actually true.
• Students will recognize that a given sample mean can lead to a “reject the null” or “fail to reject the null” depending on the alpha level.
