Create a CORRECT example of a class list log.  You will need to complete the headings and write an APPROPRIATE behavior to observe, make up children’s names, and make up the information you observed:    (12 points for a correct class list log with all components) (Obviously, we do not have a chart so type it out the best you can.)

Suppose a team of researchers conducted a prospective cohort study on the effect of physical activity on the 6-month risk of depression. To assess potential effect modification by gender, the researchers estimated the effect of physical activity on depression separately for men and women. In men, the estimated risk difference was -0.11 and the estimated risk ratio was 0.71. In women, the estimated risk difference was -0.07 and the estimated risk ratio was 0.80. Based on these effect estimates the researchers concluded that gender is indeed an effect modifier, so the researchers decided to report the conditional effect estimates in their manuscript.   Please provide an interpretation of the estimated risk ratio of 0.71. Make sure to incorporate the number 0.71 in your interpretation and assume that physical activity was the exposure level of interest and physical inactivity was the comparison level. (max. 4 points)

Suppose that the true risk difference for the association between childhood adverse events and substance abuse is 0.04 (i.e., individuals who experienced childhood adverse events have a 0.04 higher risk of abusing substances compared to individuals who did not experience childhood adverse events). Suppose that a researcher conducted a prospective cohort study and estimated a risk difference of 0.08 for the association between childhood adverse events and substance abuse (i.e., individuals who experienced childhood adverse events have a 0.08 higher risk of abusing substances compared to individuals who did not experience childhood adverse events).   What type of bias is this?

Suppose a team of researchers investigated the association between obesity and gallstones using a prospective cohort study design. The researchers were concerned about confounding by high cholesterol diet, so they performed a few different analyses in which they attempted to minimize confounding. The results of their analyses are reported in Table 1. Table 1. Unadjusted, stratified, and Mantel-Haenszel effect estimates from the hypothetical study on obesity and gallstones.   Unadjusted Estimates Estimates for the subsample with a low cholesterol diet Estimates for the subsample with a high cholesterol diet Mantel-Haenszel estimates Odds ratio 3.24 3.01 2.83 2.92 Risk difference 0.20 0.17 0.17 0.17   Based on the information in Table 1 report the following information: Was it appropriate to estimate an odds ratio using Mantel-Haenszel methods (yes/no)? (2 points) Explain why this is/is not appropriate (2 points). Was it appropriate to estimate a risk difference using Mantel-Haenszel methods (yes/no)? (2 points) Explain why this is/is not appropriate (2 points).
