This chapter introduces students to nonparametric tests, which allow us to draw inferences about nominal or ordinal data. This chapter’s focus is the Chi-Square test, used for analyzing nominal-level data. The Goodness of Fit Χ2 tests an expectation of
How to perform a chi-square test The exact procedure for performing a Pearson’s chi-square test depends on which test you’re using, but it generally follows these steps: Create a table of the observed and expected frequencies.This can sometimes be the most difficult step because you will ...
