  1. Risk Ratio
  2. Odds Ratio
  3. Relative Risk
  4. Attributable Risk

  1. Risk Ratio
  2. Odds Ratio
  3. Relative Risk
  4. Attributable Risk
Question 8 Multiple Choice (Single Answer)

What is the formula for calculating the incidence rate?

  1. Incidence rate = (Number of new cases / Population size) x Time period
  2. Incidence rate = (Number of existing cases / Population size) x Time period
  3. Incidence rate = (Number of deaths / Population size) x Time period
  4. Incidence rate = (Number of cases / Population size) x Time period
Question 9 Multiple Choice (Single Answer)

Which formula is used to calculate the prevalence?

  1. Prevalence = (Number of existing cases / Population size) x Time period
  2. Prevalence = (Number of new cases / Population size) x Time period
  3. Prevalence = (Number of deaths / Population size) x Time period
  4. Prevalence = (Number of cases / Population size) x Time period
Question 10 Multiple Choice (Single Answer)

What is the formula for calculating the mortality rate?

  1. Mortality rate = (Number of deaths / Population size) x Time period
  2. Mortality rate = (Number of new cases / Population size) x Time period
  3. Mortality rate = (Number of existing cases / Population size) x Time period
  4. Mortality rate = (Number of cases / Population size) x Time period
Question 11 Multiple Choice (Single Answer)

Which formula is used to calculate the risk ratio?

  1. Risk Ratio = (Incidence of disease in exposed / Incidence of disease in unexposed)
  2. Risk Ratio = (Prevalence of disease in exposed / Prevalence of disease in unexposed)
  3. Risk Ratio = (Mortality rate in exposed / Mortality rate in unexposed)
  4. Risk Ratio = (Odds of disease in exposed / Odds of disease in unexposed)
Question 12 Multiple Choice (Single Answer)

What is the formula for calculating the odds ratio?

  1. Odds Ratio = (Odds of disease in exposed / Odds of disease in unexposed)
  2. Odds Ratio = (Risk Ratio - 1) / Risk Ratio
  3. Odds Ratio = (Relative Risk - 1) / Relative Risk
  4. Odds Ratio = (Attributable Risk / (1 - Attributable Risk))
Question 13 Multiple Choice (Single Answer)

Which formula is used to calculate the relative risk?

  1. Relative Risk = (Incidence of disease in exposed / Incidence of disease in unexposed)
  2. Relative Risk = (Prevalence of disease in exposed / Prevalence of disease in unexposed)
  3. Relative Risk = (Mortality rate in exposed / Mortality rate in unexposed)
  4. Relative Risk = (Odds of disease in exposed / Odds of disease in unexposed)
Question 14 Multiple Choice (Single Answer)

What is the formula for calculating the attributable risk?

  1. Attributable Risk = (Incidence of disease in exposed - Incidence of disease in unexposed) / Incidence of disease in exposed
  2. Attributable Risk = (Prevalence of disease in exposed - Prevalence of disease in unexposed) / Prevalence of disease in exposed
  3. Attributable Risk = (Mortality rate in exposed - Mortality rate in unexposed) / Mortality rate in exposed
  4. Attributable Risk = (Odds of disease in exposed - Odds of disease in unexposed) / Odds of disease in exposed
