Research Configuration: Research design can be categorized into two sections including experimental and quasi-experimental research design ((Soy, 2015). In an experimental research design, the researcher needs to assign the subjects based on random selection. The subjects are assigned to particular groups for a different level of treatment. On the other hand, the quasi-experiment design suggests a process where the researcher avoids randomization, as the subjects are not selected randomly. The random assignment facilitates the researcher to control participant differences. On the contrary, it has a threat to internal validity of a particular research study (Kafle, 2013). Moreover, experimental research design does not guarantee regarding differences among participants. The researcher needs to maintain the differences while assuming a smaller sample size for the research analysis. In some cases, the researcher may match participants across control and treatment. With the involvement of experimental research design, the researcher treats each pair of participants as one virtual participant (Robson & McCartan, 2016). On the other hand, the quasi-experimental design can be developed by utilizing a control group, measuring moderators. Taylor, Bogdan & DeVault (2015) have argued that quasi-experimental design indicates the time series design, where a series of observations are developed over time. However, the development occurs without intervention and with intervention. In
