examine two of the provided articles. One article use a quasi-experimental design; and one article that uses a factorial experimental design
1.Quasi-Experimental Article:
Pata, R. W., Lord, K., & Lamb, J. (2014). The effect of Pilates based exercise on mobility, postural stability, and balance in order to decrease fall risk in older adults.Journal of Bodywork and Movement Therapies, 18(3), 361-367.
2.Factorial Article:
Allison, M. & Lee, C. (2015). Too fat, too thin: Understanding bias against overweight and underweight in an Australian female university sample. Psychology & Health, 30(2), 189-202
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?
