# Experience 13 - Goodness Of Fit (GOF) Tests

**Goodness-of-Fit Tests**

**Why**

The goodness-of-fit test will provide us with an inferential procedure for testing whether a frequency distribution follows a specific shape. In many situations testing the mean alone is not enough and we need to know if a data set is distributed a certain way.

**Learning Objectives**

- Know the basic features of the chi-square distribution
- Understand the procedure for conducting goodness-of-fit tests

**Performance Criteria**

- The learner will calculate p-values for goodness-of-fit tests using technology
- The learner will write up each part of a goodness-of-fit test using correct notation and complete sentences.
