"e;aIt is a great textbook for undergrads who are being exposed to statistics in the field for the first time and for Masters students who need a better grasp of the fundamentals of statistics before taking more advanced coursesa"e; aCalli M. Cain, University of Nebraska at Omaha"e;A must-have textbook for Instructors and students alike in the fields of Criminology and Criminal Justice.A The book is user-friendly."e; aBonny Mhlanga, Western Illinois UniversityAn Introduction to Statistics in Criminology and Criminal JusticeStatistics for Criminology and Criminal Justice, Third Edition demonstrates how statistics is relevant to a students life and future career by illustrating the logical connections between basic statistical concepts and their real-world implications in criminology and criminal justice. Written for students with a limited mathematical background, author Jacinta Gau eases student anxiety around statistics by simplifying the overarching goal of each statistical technique and providing step-by-step instructions for working through the formulas and numbers. Students use real data from the field to build a foundational knowledge of statistics, rather than merely memorizing key terms or formulas.A New to the Third Edition NEW Thinking Critically feature encourages students to apply the concepts from the chapter to real-life scenarios, with open-ended questions that are designed to inspire students to think about the nuances of science, statistics, and their application to criminal justice.A Additional illustrations and examples in every chapter keep students engaged with the content and offer ample opportunities for them to practice the techniques.A New and updated data sets from a wide range of relevant sources, such as the NCVS and UCR, BJS, LEMAS, the Census of Jails, and much more have been incorporated to give students insights into the state of criminal justice research today.A New research on critical topics encourages students to discuss changes happening in the field such as the Census of Jails, inmate-on-staff assaults in prisons, and homicide rates. Practicing Statistics Whiteboard Videos, available in SAGE edge, walk students through statistical calculations to reinforce key concepts.A Previous edition errors have been corrected by a statistician.A Give your students the SAGE edge!SAGE edge offers a robust online environment featuring an impressive array of free tools and resources for review, study, and further exploration, keeping both instructors and students on the cutting edge of teaching and learning.
