Welcome to the Companion Website!

This site is intended to enhance your use of Statistics for Criminology and Criminal Justice by Jacinta Gau. Please note that the materials on this site are especially geared toward maximizing your understanding of the material.

Statistics for Criminology and Criminal Justice, Second Edition is an introductory statistics text for undergraduate criminology and criminal justice majors. The topics and engaging presentation style are targeted to students who have a basic background in algebra but who have had little or no exposure to the study of statistics. The overarching goals of the book are to demonstrate to students that statistics used in criminal justice can be enlightening and eye-opening and, that pre-conceived notions of their academic inadequacies coming into the course are false.


The fully updated Second Edition includes new learning objectives and learning checks to help guide students through the material and ensure content understanding and retention. Coverage of the fundamental areas in statistics begins with descriptive statistics, moves into probability, and ends with regression to make the content easier for students to follow. By use of real data and research, emphasis is placed on balancing thoroughness with ease of understanding in order to show students the importance and relevance of statistics in their future criminal justice careers.
