Summary

This is the only book that introduces students to the statistical methods of criminology and criminal justice and shows how they are actually used. Each detailed yet accessible chapter combines instruction in statistical analysis with investigations of key research questions in the field; for example, what are the causes of crime? Useful at both the introductory and intermediate levels, the text contains in-depth coverage of descriptive statistics, including graphical displays of data and exploratory data analysis, along with bivariate and multivariate analyses. Emphasis is placed equally on calculation and interpretation.
