In the world of statistical analyses, there are many tests and methods that for categorical data. Many become extremely complex, especially as the number of variables increases. But sometimes we need an analysis for only one or two categorical variables at a time. When that is the case, one of these seven fundamental tests may come in handy.
These tests apply to nominal data (categories with no order to them) and a few can apply to other types of data as well. They allow us to test for goodness of fit, independence, or homogeneity—and yes, we will discuss the difference! Whether these tests are new to you, or you need a good refresher, this training will help you understand how they work and when each is appropriate to use.
- Chi-Square Goodness of Fit Test
- Chi-Square Test of Independence
- Cochran-Mantel-Haenszel Test of Independence
- Chi-Square Test of Homogeneity
- Two-Sample Z Test for Proportions
- Fisher Exact Test
- McNemar Test of Symmetry
