The results of a survey might provide lots of information on characteristics of students at your school, such as what proportion eat breakfast regularly, like first-period classes, have a job, or own a car. Does a “yes” response to one of these characteristics help us predict what the response of that same person will be to another characteristic? Is a person who eats breakfast likely to have an early class? Is a person who has a job likely to own a car? Looking for associations between categorical variables is an important part of the analysis of frequency data. How to begin the process of measuring association is the subject of this lesson.
