Overview
This chapter takes us further into inferential analysis of categorical data. Two prior chapters have concentrated on categorical variables. In Chapter 6, we learned to compute relative frequencies, which we then used to illustrate concepts and rules of probability. In Chapter 10, we studied dichotomous categorical variables to learn about confidence intervals and hypothesis tests for a single population proportion.
In this chapter, we’ll consider two basic issues. First, we’ll learn to draw inferences about a categorical ...
