Categorical Statistics for Communication Research / Edition 1

Categorical Statistics for CommunicationResearch presents scholars with a discipline-specific guide to categorical data analysis. The text blends necessary background information and formulas for statistical procedures with data analyses illustrating techniques such as log- linear modeling and logistic regression analysis.

  • Provides techniques for analyzing categorical data from a communication studies perspective
  • Provides an accessible presentation of techniques for analyzing categorical data for communication scholars and other social scientists working at the advanced undergraduate and graduate teaching levels
  • Illustrated with examples from different types of communication research such as health, political and sports communication and entertainment
  • Includes exercises at the end of each chapter and a companion website containing exercise answers and chapter-by-chapter PowerPoint slides
