Statistics Question

Description

Chi square quiz

Chi Square is a non parametric statistical technique that explores relationships among nominal variables. It is not correlation, but the interpretation of chi square output is similar in nature to correlation. That said, it is important to know that they are not the same, and are not to be confused or called the same name. They are separate, distinct procedures.

This quiz focuses on your knowledge of this technique with data that are analogous to the examples presented in the lecture recording and the posted data files in Canvas.
