Definitions:

Nonequivalent Control Group Design

is a quasi-experimental design in which subjects are not randomly assigned to the experimental and control groups, potentially leading to selection bias.

Incidence of Crime

The frequency or rate at which crimes occur in a particular area over a specific time period.

Quasi-Experiments

Research designs that attempt to establish cause-effect relationships among the variables being studied, without the full control or random assignment inherent in true experimental designs.

Equivalent Groups

In experimental research, two or more groups that are made to be as similar as possible through random assignment, ensuring that differences in the experiment's outcome can be attributed to the treatments received.
