Question
For this assignment, again, it is beneficial that you keep the topic you would like to research for the capstone proposal in mind. The capstone will require a literature review for your proposal, of which you may use articles obtained during this course.
Select a peer-reviewed, experimental research study that exemplifies a two-group design (two independent groups design, two matched groups design, or repeated measures design) and a factorial design (use keywords method, results, and discussion in your Boolean search). These studies can be found using tools such as the GCU Library and Google Scholar.
Write a 500-750-word paper in which you:
- Compare the two research designs
- Identify the independent variable(s), dependent variable, and any possible extraneous variable
- Identify main effects and interactions for the factorial design
- Explain if the study has a random sample and/or random assignment? Were there other limitations that were noticed?
Solution
Experimental Design
The main purpose of this paper is to critique and compare an article that utilizes a two-group design and that uses a factorial design. At first, a two-group design is an experimental design that entails two groups: a treatment group and a control group. According to Myers and Hansen (2012), this type of experimental design uses a random assignment, thus increasing its internal validity. Additionally, this research design conducts a pre-test and a post-test to determine any relationship between the two groups. When trying to find a cause and effect association between two variables using the two-group design can be beneficial. On the other hand, a factorial design investigates the relationship between several dependent variables and the dependent variable. This research design is beneficial when applying it in establishing the main and interaction effects of variables.
