  1. Of the study methods discussed in class (single case, observational, survey, quasi-experimental, or single factor), which method would be ideal for the researcher to use? Why?
  2. Based on the study method you identified, briefly describe how the researcher could structure their study.
  3. What are strengths and limitations to the use of this study method?
  4. Each scenario has a possible bias/error associated with it. Based on the bias/error listed for this scenario, how could this affect the study results, and how could a researcher work around this?
