A design in which two or more independent variables, at least one of which is manipulated, are simultaneously studied to determine their independent and interactive effects on the dependent variable. Strong experimental design. See Figure 12.15.

1. Experimental studies and observational studies both make causal comparisons of exposed and non-exposed groups. Clarify the primary advantage of using a randomized experiment for this purpose. (50 word maximum) 2. Why was blinding employed in the Colford et al. study? Give examples of improper influences that would have occurred without blinding?

Quasi-experimental Designs – An experimental approach (control and test groups) where participants are not randomly assigned or groups such as classes are assigned either randomly or not randomly. Acceptable research design examples include: Non-randomized [Non-equivalent] Control Group Pretest-Posttest Design. Solomon Four Group Design.

Non-experimental research, e.g., case studies, surveys, correlation studies, is non-manipulative observational research usually conducted in natural settings. While laboratory-controlled experimental studies tend to be higher in internal validity, non-experimental studies tend …

C (R) O O The advantage here is the randomization, so that any differences that appear in the posttest should be the result of the experimental variable rather than possible difference between the two groups to start with. This is the classical type of experimental design and has good internal validity.

c) Explain The experimental design was quasi-experimental. I believe this could be an appropriate fit for the research question, as the authors describe several studies in which educational interventions in schizophrenic individuals taking antipsychotics have been shown effective in preventing weight gain.

Much of the study of experimental design is devoted to controlling extraneous variables More on control later in this lecture. Example of controlling for an extraneous variable – from Biderman, Nguyen, Cunningham, & Ghorbani (Journal of Research in Personality, 2011).
