Parametric Tests

In the previous chapter, we introduced the concept of a hypothesis test and showed several applications of the z-test. The z-test is a type of hypothesis test in a family of hypothesis tests called parametric tests. Parametric tests are powerful hypothesis tests, but the application of parametric tests requires certain assumptions to be met by the data. While the z-test is a useful test, it is limited by the required assumptions. In this chapter, we will discuss several more parametric tests, which will expand our parametric tool set. More specifically, we will discuss the various applications of the t-test, how to perform tests when more than two subgroups of data are present, and the hypothesis test for Pearson’s correlation coefficient. We will complete the chapter with a discussion on power analysis for parametric tests.

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

  • Assumptions of parametric tests
  • T-test—a...
