CHAPTER 16 Analysis of Categorical Data

LEARNING OBJECTIVES

The overall objective of this chapter is to give you an understanding of two statistical techniques used to analyze categorical data, thereby enabling you to:

1. Use the chi-square goodness-of-fit test to analyze probabilities of multinomial distribution trials along a single dimension.

2. Use the chi-square test of independence to perform contingency analysis.
