Chapter 2:
Question 5: Your answer is partially correct but not complete. You wrote "COHORT STUDY", which is
part of the correct answer. The full correct answer is "Cohort Study or Nested-Case Control Study".
While a cohort study is indeed appropriate for the scenario described, a nested case-control study could
also be used.
Question 10: Your answer is incorrect. You marked this as TRUE, but the correct answer is FALSE. The
statement "A cohort study involves a group of individuals who has a disease compared to a similar group
without the disease" is false. This description actually refers to a case-control study. A cohort study, on
the other hand, follows a group of individuals over time to observe the development of outcomes,
rather than starting with cases (those with the disease) and controls (those without).
