Introduction: the analysis of categorical data

• Categorical data is perhaps the most common form of data in the social sciences
• But the best-established techniques favour continuous data
  • t-tests, correlations
  • Regression analysis, ANOVA
  • Factor Analysis, etc.
• However, a battery of techniques are available for categorical data, including
  • cross-tabulation
  • loglinear modelling, and
  • binary, multinomial and ordinal logistic regression
