¶ … True" Experiments vs. Quasi-Experimental Designs
What qualities of the quasi-experimental design are evident in this study?
This study was specifically designed to test the efficacy of a new program designed to improve police responses to cases involving domestic violence. Through the Second Responders Program, trained social workers would follow police after domestic violence-related calls and provide victims with counseling and information about social support services if the victims wished to leave their abusive partners. To evaluate the program, "field researchers contacted eligible subjects and attempted to interview them within 1 week of the domestic violence incident to which police were called; the second interview took place 6 months later" (Lane et al. 2004: 4).
Because the city of Richmond implemented the Second Responders Program in only two of its four police precincts, the researchers chose to use as a control group the precincts...
The experimental group consisted of the precincts were the program was implemented; the control group consisted of the precincts where the program was not implemented. Because the different precincts were within a relatively similar geographic range, they were deemed to be similar enough to warrant a comparison. The same criteria for domestic violence was used when comparing the results of the interviews of both groups and "only cases that occurred during the Second Responders' working hours -- 6 p.m. To 9 a.m. -- were included to ensure experimental and control group comparability" (Lane et al. 2004: 4). Additionally, only female subjects over the age of 18 were compared in both groupings, to ensure demographic homogeneity. Thus although the groups were not part of a randomized control experiment, considered the 'gold standard' of clinical validity in experimental design, the similarities between the two groups were designed to ensure that the…

Eveland's research design is quasi-experimental. The sample populations for the experiment are not randomly selected. There is structure to the experiment with more than one form of measurement during the research process. Quasi-experimental design includes multiple groups and multiple waves of measurement. While there were not a significant number of groups in the experiment, there was more than one. At more than one point in the experiment, measurements were
Methodology for �Why Having a College Education is More Beneficial as Opposed to not Having a College Education�IntroductionThe purpose of this research study is to investigate the benefits of having a college education as opposed to not having a college education.

new reading program on a student's ability to learn to read. Because the program is designed specifically for helping new readers learn basic reading skills the experimenter chooses only beginning first-grade students as the population of interest. Thus, as the subject variable is one that cannot be the target of random assignment (you cannot randomly assigned subjects to the first-grade) a nonequivalent control group pre-test post-test quasi-experimental design is
Unit 3 Question What types of research question(s) can best be addressed through the use of case studies? What are the advantages and disadvantages of the case study approach? The case study approach is favored in many research studies in the social sciences, particularly sociology and anthropology. Case studies are useful in examining questions about a particular social group, and also explain phenomena with multiple causes, such as 'juvenile delinquency.' Finding ways to
In the experimental community, the researchers instituted a media campaign to increase seat-belt usage, followed by increased police enforcement of the seat-belt law. It was found that the percentage of drivers using seat belts increased in the experimental community but remained stable or declined slightly in the comparison community (Piquero and Piquero, 2002). An example of the before-and-after design would be the analysis of the impact of the Massachusetts Bartley-Fox
