Sample item

What measure compares risk in exposed versus unexposed groups?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Relative risk

The defining Epidemiology principle supports Relative risk; it directly accounts for the forensic observation, evidence requirement, or public-health measure in the question.

Option by option

  • A. Specificity

    Specificity may be useful elsewhere but is not the best answer here.

  • B. Standard deviation

    Standard deviation is not consistent with the finding or appropriate action described.

  • C. Median

    Median does not establish the requested epidemiology conclusion.

  • D. Relative risk (correct)

    Correct. Relative risk best fits the important clue in this sample.
