The Practice of Research in Criminology and Criminal Justice, Seventh Edition, follows the research process from questions and study design to analysis and reporting. Bachman and Schutt use policing, courts, corrections, and juvenile justice examples to introduce sampling, measurement, data collection, ethics, and qualitative and quantitative methods for students and practitioners.

Research design, sampling, and measurement in criminal justice settings
Current listed price $23.00Regular price $49.00Digital ebook
Criminal justice settings give context to the methodological decisions examined in this textbook. Readers consider how to define a research problem, select experimental or other designs, construct measures, and identify a sample. Surveys, interviews, observation, and existing records illustrate alternative ways to gather evidence about crime and justice institutions.
Analysis includes quantitative and qualitative approaches, while ethics material addresses consent, confidentiality, review procedures, and research involving vulnerable populations. Examples also introduce social network analysis, cybercrime measurement, and intelligence-led policing. Guidance on communicating findings connects research activity with reports and policy discussions. The seventh edition serves upper-level undergraduate and graduate methods courses and practitioners evaluating studies, programs, or crime-related data.

Inside The Practice of Research in Criminology and Criminal Justice, 7th Edition.
Bachman and Schutt treat research as a chain of decisions, each one constraining the next. A vague question produces a muddled design; a loose measure produces a confident but empty result. Working through examples drawn from courts, policing, juvenile justice, and corrections, the book shows how to keep question, method, evidence, and conclusion aligned from start to finish.
Early chapters cover purposes of inquiry, theory, and the ethics of studying people entangled with justice institutions. Concepts and measures come next, then sampling and the logic of causal comparison. Experiments, surveys, and fieldwork each get a chapter, followed by secondary records, crime mapping, networks, program evaluation, and mixed designs. The final section handles quantitative and qualitative analysis and the writing of findings. Examples stay close to real agency settings, and the text repeatedly asks what a given piece of evidence can and cannot support.
Purpose, theory, and harm
A study begins by deciding whether it will describe how common something is, explore an unfamiliar process, explain variation, or evaluate a program. That choice dictates what must be observed. Ethics is not a single form to sign: recruitment, consent, record access, storage, and publication each create risk, and people in justice settings may find refusal costly. Confidentiality must survive combined details, not just removed names.
Choose the aim before the technique
Map risk at every stage
Guard against re-identification by detail
Chs. 1–3
Turning concepts into measures
Conceptualization says what a term covers, for instance which acts qualify as victimization. The next step, operationalization, says how researchers will observe it, using reports, official records, or structured watching. Those indicators measure different processes, because a recorded incident depends on occurrence plus decisions to notice, report, classify, and file it. Consistency and fit are separate tests, and a reliable count of referrals can still miss misconduct.
Fix what counts as the phenomenon first
Distinguish reliability from validity
Check an indicator against a second source
Ch. 4
Selection and causal comparison
Generalization rests on how the sample was drawn. Probability designs let you estimate uncertainty where each unit's chance of selection is known, and stratification and clustering solve practical problems at a cost. Causation is a different matter altogether: it needs association, proper time order, and a serious effort to rule out rivals. Random assignment builds comparable groups on average, while matching and before-after designs lean on extra assumptions.
Match sampling frame to population
Separate who enters from what they get
Attack alternatives before claiming cause
Chs. 5–7
Surveys, fieldwork, and records
Survey answers hinge on wording, the recall period, answer choices, administration mode, and who agrees to respond. Then probe one specific experience in a defined period and check how participants interpret the question. Observation and interviews expose routines, viewpoints, and informal practice, but only if you document access and your own effect on the scene. Existing records need scrutiny too: who made them, under what categories, and whether definitions shifted mid-period.
Ask questions people can actually answer
Log how access and presence shaped data
Interrogate the record's categories
Chs. 8–10
Maps, programs, and mixed designs
A crime map shows recorded incidents across space, so positional accuracy, boundaries, reporting habits, and who is exposed to risk shape the picture. Network analysis depends just as heavily on what is treated as a tie. A cluster is a lead, not an explanation. Program evaluation should track delivery as well as results, since an unchanged outcome may mean the activities never reached anyone; mixed methods pay off when the pieces are integrated on purpose.
Treat a hot spot as a question
Measure what the program delivered
Integrate the strands on purpose
Chs. 11–13
Analysis and honest reporting
Look at distributions and gaps in the data before comparing groups, and let the measurement level decide which summaries make sense. Qualitative work needs systematic coding, cross-case comparison, and a search for cases that resist the emerging story. Then write so a reader can reconstruct what you did: question, sample, measures, results, limitations. Report both uncertainty and patterns you did not expect, and keep findings from one setting separate from guesses about elsewhere.
Inspect distributions before testing
Keep conclusions tied to the data
State the claim's reach plainly

Key takeaways
Identify what an indicator actually measures and how the value entered the dataset.
Keep selection into a study distinct from assignment to a treatment condition.
Read the implementation data before crediting a program with an observed outcome shift.
Undergraduates studying crime and justice, graduate students beginning methods training, and practitioners who need to read evaluation research critically. Familiarity with basic social science helps, but the examples carry readers who are new to research design.
