Chapter 12, Problem 1RQE

Summary Introduction

Introduction:

A quasi-experiment does not randomly assign subjects to control and experimental groups. Qualitative design allows for more in-depth results because responses are not confined to numerical or closed-ended questions. Experiments attempt to establish cause and effect relationships between variables.

Explanation of Solution

Answer and explanation:

(This question calls for a subjective answer. This is an example of an appropriate response.)

I would use a combination of evaluation designs to determine the effectiveness of an alcohol- and drug-free teen center. Rates of teen use and/or abuse of alcohol or drugs would need to be established before the center is opened. These data should be readily available, as they may have motivated the desire for the teen center in the first place. Qualitative analysis would include interviews with the teens after they have been using the center for a while to determine their attitudes toward the effort. An experimental evaluation would occur in comparing drinking and drug use rates before and after the center has been open for some time. A quasi-experimental approach would likely be needed, since it would be unethical to create a control group that has access to the center, and an experimental group denied its use.
