Fundamentals of Research in Criminology and Criminal Justice

I am a professor of CJ at a state university where I teach Research Design at the junior/senior level. I use this book in my class and the students seem to like it.

I teach out of this book, and can say that, for instructors who want their students to acquire a deep understanding of research methods, and of science itself, this book (and its various relatives, all with Schutt as author or co-author) is by far the best. It's also available bundled with SPSS.
