• Explain the advantages and disadvantages of each of the observational study designs.
• Explain how to interpret the basic results of each study design.

Answer 1

Answer 1) I would prefer YPLL rate over YPLL because YPLL rate will provide a better sense of burden of deaths from homicide and legal intervention between white and black males. This is because the

YPLL rate= (YPLL/ number of individual below the end point)* 10ⁿ.

Therefore, it will give us the information about the burden of deaths along the population size which may be different for white males and black males.
