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.
