Introduction to Inferential Statistics

In this chapter, we get into actual analyses—the fun part of data analysis. In this chapter, you will need to know what t-test, chi-square, correlation, and simple linear regression analyses are, as well as when to use them. We also included some hands-on practice for these analyses to help reinforce how and why each analysis is used. If you like, you are free to follow along and practice on your own, or you can simply read through and move on. Do what makes you feel confident in your understanding of the material.

In this chapter, we’re going to cover the following main topics:

  • Understanding t-tests
  • Knowing chi-square
  • Calculating correlations
  • Understanding simple linear regression
