What, if any, variables were controlled in the analysis to reduce the risk of spurious relationships and rival causal factors? (200 words at least)
3. Which of the 8 possible variables (factors) listed on page 68 of your textbook that affect the internal validity of the conclusions concern you the most as it relates to this research article? Explain and justify your response. (200 words at least)
4. Briefly describe the difference between a cross-sectional and longitudinal design. What are the pros and cons of using each? Describe the longitudinal aspect of Kempinen & Kurlychek’s (2003). (200 words at least)
