Assignment 1: Development of a Research Scenario
Pre- and Posttest Control Group Design
Develop a hypothetical research scenario that would necessitate the use of a Pre- and Posttest Control Group Design. The research can be either experimental or quasi-experimental.
| Group | Pretest | Treatment | Posttest |
| 1 | O1 | X | O2 |
| 2 | O1 | – | O2 |

1. Identify the research scenario including the relevant independent and dependent variables.
2. Develop the appropriate primary research question to be associated with this design.
3. Discuss the sampling strategy and technique used to access the appropriate sample.
4. Indentify the assignment technique to be utilized. Discuss whether it will be experimental or quasi-experimental research.
5. Identify what type of comparison group will be used opposite of the treatment group. Why would this type of comparison group used?
6. In accordance with the assignment technique and comparison group, discuss the various control techniques that will be utilized with this specific design.
7. Discuss the major threats to validity associated with this design and type of research (experimental or quasi-experimental). How will these threats be addressed in accordance based on the discussion of the control techniques in number 6?
8. Enter the relevant variables in the chart below.
9. Briefly discuss any limitations associated with this research scenario and the specific design.
