Overview
1. Review the video on Normal Distribution in the Calculations section of the "Statistics Visual Learner" media piece. Bob compares his SAT Verbal score of 400 to Marge's ACT Verbal score of 20. "I beat you," he exclaims. "My score is 20 times your score!" Although his multiplication is good, his logic is faulty. Explain why.
2.Review the video "Linear Correlation" in the Calculations section of the "Statistics Visual Learner" media piece. It is sometimes said that the higher the correlation between two variables, the more likely the relationship is causal. Do you think this is correct? Discuss.
3.Discuss the strengths and weaknesses of correlational and regression studies; discuss concepts such as positive and negative correlations, correlation coefficients, confounding variables, and causality.
