A team of researchers wants to know whether a new crime prevention program is really effective in reducing crime in young adolescents. The researchers find two middle schools, Adams Middle School and Monroe Middle School, which serve similar kinds of students and report similar rates of theft, physical assault, and vandalism. The researchers implement the program at Adams and use Monroe as a control group. Afterwards, they discover that crime has decreased at Adams but not at Monroe. This study is a good example of a(n) _______ design.

 A.correlational   
 B.experimental   
 C.cross-sectional   
 D.quasi-experimental

D.quasi-experimental

I think. Experiments that take advantage of natural occurrences are quasi-experiments, for example, comparing achievement level of first-born children with that of later-born children; or comparing student performance at two schools, one of which has a lower student-teacher ratio. The experimenter is unable to assign subjects to treatment level - the subjects are already in pre-existing groups.

Quasi-experiments are sometimes called natural experiments because membership in the treatment level is determined by conditions beyond the control of the experimenter (subjects are already in the box). An experiment may seem to be a true experiment, but if the subjects have NOT been randomly assigned to the treatment condition, the experiment is a quasi- experiment (quasi = seeming, resembles).
