• Evaluate whether the researchers’ conclusion follows logically from the evidence presented.
• Identify threats to internal and external validity that might apply to how this study was conducted.
• Determine whether validity threats were addressed by the researchers. If so, describe how this was done.
• Summarize ethical considerations that were mentioned in the research report.
• Assess what ethical considerations apply to the design of the study but that were not mentioned by the researchers.
• Explain how you might do a study on this topic differently and why your approach would be more appropriate than the one used by the researchers.
• Evaluate whether a quantitative approach would be useful for the research topic you chose in Week 1.
• Describe the actions you would take to ensure that a quantitative study on your topic would be ethical.
• Support your evaluation of the study with citations and references of the required readings and other peer-reviewed sources.
