A Comprehensive Guide to Exploring Non-Numerical Data

In the realm of data analysis, categorical data plays a crucial role in understanding complex phenomena and making informed decisions. Unlike numerical data, which measures continuous variables, categorical data organizes information into distinct groups or categories. An to Categorical Data Analysis, a highly acclaimed book in Wiley's Probability and Statistics series, provides a comprehensive and accessible guide to the analysis of this often-overlooked type of data.

What is Categorical Data Analysis?

Categorical data, also known as qualitative data, consists of non-numerical information that falls into specific categories. Examples include gender, ethnicity, occupation, and brand preferences. The analysis of categorical data involves exploring the relationships between these categories and understanding the underlying patterns to draw meaningful s.
