Learning about 2-Sample T-Tests with Guitar Hero

Learning about 2-Sample T-Tests with Guitar Hero

Description:

-Demonstrate how to compare independent means using a 2-sample t-test
-Review assumptions and conditions
-Present how to calculate the p-value from the t-distribution using the appropriate degrees of freedom using a graphing calculator

This learning packet will demonstrate how to perform a 2-sample t-test to determine if there is a significant difference between two independent quantitative variables. In this experiment, we will be testing if there is a significant difference in gender ability on Wii's Guitar Hero.

Getting Prepared to Perform a Hypothesis Test to Compare Independent Means

In this video, I set up the null and alternative hypothesis, review the conditions and assumptions that need to be satisfied in order to perform a 2-sample t-test, and introduce the 2-sample t-test equation.
