Independent T-Test

Chapter 7 introduced the idea of thinking through a business question and building a hypothesis test around that query, and it elucidated on the five steps to run a statistical inquiry. This chapter shows how to implement those five steps using the statistical test referred to as the independent t-test or the student's t-test. Again, a small dataset is used for demonstration purposes only to show how to use the independent t-test and understand its purpose. You'll want to use a larger dataset in real-life situations.
