Assignment
The task for this week requiresme to examine the two of the provided articles.. One article uses a quasi-experimental design; and one article uses a factorial experimental design. These two articles are based onmy program specialization:
Forensic Psychology
Quasi-Experimental Article:Boxer, P., Kubik, J., Ostermann, M., & Veysey, B. (2015). Gang involvement moderates the effectiveness of evidence-based intervention for justice-involved youth. Children and Youth Services Review, 52, 26-33. doi:10.1016/j.childyouth.2015.02.012

Ithen answer the following based on the articles provided formy specialization.
For the Quasi-Experimental Design article, answer the following:
1. Operationally define both the (quasi) independent and dependent variables.
2. Explain how the groups differ.
3. Explain why, in this case, a quasi-experimental design was used (rather than an experimental design).
4. Describe the threats to validity (external or internal) in article. Did authors address these threats?
For the Factorial Design article, answer the following:
1. Operationally define both the (quasi) independent and dependent variables.
• Explain the levels of the independent variable.
• How many independent variables were used?
• Describe the design (e.g. 4 x 2 x 2 factorial design)
2. Identify the main effects in this study (e.g. , experienced versus non-experienced; cognitive therapy versus psychoanalytical).
3. Explain how your groups differ.
4. Explain why, in this case, a factorial design was used.
5. Did the authors use a participant variable?
• Why or why not?
• What additional information was obtained including a participant (or might be obtained, if a participant was not included)?
6. Describe the threats to validity (external or internal) in article.
• Did authors address these threats?
Length: 5-7 pages
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
