True and Quasi-Experimental Designs Essay Example

Essays on True and Quasi-Experimental Designs Essay The paper "True and Quasi-Experimental Designs" is a worthy example of an essay on education. Design is the structure of any  scientific  work that gives direction and  systemizes  the research. In view of the  second  responder's program: coordinated police and social service response to domestic violence, it is clear that the researchers employed the quasi-experimental design; this being both qualitative and quantitative method (Gribbons Herman, 1997). Field findings of the researchers  are based  on two waves of victims: women who received  second  responder intervention, and women who received police intervention. The experimental and control groups  were defined  by a geographical boundary, a wide range of  demographical  data  was collected. The  second  responder's program  was implemented  in two of its four police precincts’ in Richmond. Interview findings  were presented  in four broad areas: services provided by police and responders, attitude towards police and second responders, the  probability  of receiving follow up, and the likelihood of receiving protection. The study opted for a quasi research design over a true experimental design  because  the true experimental design tends to  prove  or reject a hypothesis mathematically with statistical analysis.  It has more of a quantitative design  method  reason  for this could be due to  the random  assigning of groups that  are approached  in the later design (Gribbons Herman, 1997). Again the true experimental design demands a viable  control group, this design suggests that only one variable can be manipulated and tested yet we see that the research involved testing of more than one variable. The true experimental design also involves a process whereby the tested subjects  are randomly assigned  to either experimental or control groups. However, what we see in the study is that the experimental group  was drawn  from the first and second precincts whereas the control group from third and fourth precincts.
