A type of research design for conducting studies in field or real-life situations where the researcher may be able to manipulate some independent variables but cannot randomly assign subjects to control and experimental groups. The procedures of quasi-experimentation were developed mainly in the context of evaluation research projects. For example, you cannot cut off someone's unemployment benefits to see how well he or she could get along without them or to see whether an alternative job-training program would be more effective for some unemployed persons. But you could try to find volunteers for the new program. You could compare the results for the volunteer group (experimental group) with those of people in the regular program (control group). The study is quasi-experimental because you were unable to assign subjects at random to treatment and control groups. Questionnaire - A group of written questions to which subjects respond. Some restrict the use of the term "questionnaire" to written responses.
