Which quasi-experimental design would be appropriate to evaluate the effectiveness of the chairpersons intervention?
Why? Given that a true experiment is not an option (probably because of the perceived difficulty of implementing random assignment of students to residence halls) the two alternative quasi-experimental designs are a nonequivalent control group design or a time series with nonequivalent control group design. The time series with nonequivalent control group design is preferred because it increases the reliability of the study because there are multiple measurements before and after the treatment. If the chairperson of the committee wanted to make a decision soon after the first term in which the quiet hours have been implemented, then the nonequivalent control group design may be preferred. Either the time series with nonequivalent control group or the nonequivalent control group design is preferable to a simple time series design because they control for threats to internal validity such as history and maturation.
