Problems of designing an experimental research design

Case study provided in Skidmore’s article utilizes casual designs tests while the null hypothesis uses confirm design. The primary objective of the study is proving that manipulation of independent variables does not affect the active participation of online students. Among the provided research design in the Skidmore 2008 article are pretest-posttest control group design, the posttest-only control group, and Solomon four-group designs. Following the nature of my study, Solomon four-group designs present the fittest design. Making use of the design the study population will be divided into two group of conducting the study and two control groups. Moreover, using the most appropriate sample size selection method helps in reducing threats of the study. Aiming at realizing ethical principles of the research, I will base the study on true presentation of human experiences globally.
