Question 6 Multiple Choice (Single Answer)

What is the role of confounding in epidemiology?

  1. Confounding is a factor that is associated with both the exposure and the outcome, and can bias the results of an epidemiological study.
  2. Confounding is a factor that is associated with the exposure but not the outcome, and can bias the results of an epidemiological study.
  3. Confounding is a factor that is associated with the outcome but not the exposure, and can bias the results of an epidemiological study.
  4. Confounding is a factor that is not associated with either the exposure or the outcome, and cannot bias the results of an epidemiological study.
Question 7 Multiple Choice (Single Answer)

What is the purpose of a case-control study in epidemiology?

  1. To investigate the relationship between an exposure and an outcome by comparing a group of people with the outcome to a group of people without the outcome.
  2. To follow a group of people over time to investigate the relationship between an exposure and an outcome.
  3. To identify and summarize existing research on a specific topic.
  4. To design and conduct a new epidemiological study.
Question 8 Multiple Choice (Single Answer)

What is the difference between a relative risk and an odds ratio in epidemiology?

  1. Relative risk is the ratio of the incidence of an outcome in an exposed group to the incidence of the outcome in an unexposed group, while odds ratio is the ratio of the odds of an outcome in an exposed group to the odds of the outcome in an unexposed group.
  2. Relative risk is the ratio of the prevalence of an outcome in an exposed group to the prevalence of the outcome in an unexposed group, while odds ratio is the ratio of the odds of an outcome in an exposed group to the odds of the outcome in an unexposed group.
  3. Relative risk is the ratio of the incidence of an outcome in an exposed group to the prevalence of the outcome in an unexposed group, while odds ratio is the ratio of the odds of an outcome in an exposed group to the prevalence of the outcome in an unexposed group.
  4. Relative risk is the ratio of the prevalence of an outcome in an exposed group to the incidence of the outcome in an unexposed group, while odds ratio is the ratio of the odds of an outcome in an exposed group to the incidence of the outcome in an unexposed group.
Question 9 Multiple Choice (Single Answer)

What is the purpose of a randomized controlled trial in epidemiology?

  1. To investigate the relationship between an exposure and an outcome by randomly assigning participants to either an exposed group or an unexposed group.
  2. To follow a group of people over time to investigate the relationship between an exposure and an outcome.
  3. To identify and summarize existing research on a specific topic.
  4. To design and conduct a new epidemiological study.
Question 10 Multiple Choice (Single Answer)

What is the difference between a cross-sectional study and a cohort study in epidemiology?

  1. A cross-sectional study is a type of observational study in which data is collected from a population at a single point in time, while a cohort study is a type of observational study in which data is collected from a population over time.
  2. A cross-sectional study is a type of experimental study in which participants are randomly assigned to either an exposed group or an unexposed group, while a cohort study is a type of observational study in which data is collected from a population over time.
  3. A cross-sectional study is a type of observational study in which data is collected from a population over time, while a cohort study is a type of experimental study in which participants are randomly assigned to either an exposed group or an unexposed group.
  4. A cross-sectional study is a type of experimental study in which participants are randomly assigned to either an exposed group or an unexposed group, while a cohort study is a type of observational study in which data is collected from a population at a single point in time.

  3. To collect and analyze data from a population.
  4. To interpret the results of an epidemiological study.
Question 12 Multiple Choice (Single Answer)

What is the difference between a case-control study and a cohort study in epidemiology?

  1. A case-control study is a type of observational study in which a group of people with a disease or outcome (cases) are compared to a group of people without the disease or outcome (controls), while a cohort study is a type of observational study in which a group of people are followed over time to investigate the relationship between an exposure and an outcome.
  2. A case-control study is a type of experimental study in which participants are randomly assigned to either an exposed group or an unexposed group, while a cohort study is a type of observational study in which a group of people are followed over time to investigate the relationship between an exposure and an outcome.
