Answer to Question 1

Ans: B
Feedback:
Incidence rate is the measure of the probability that people without a certain condition will develop that condition over a period of time. Incidence density is the use of a person-time denominator in the calculation of rates. A person-day reflects one person at risk for 1 day, and a person-year represents one person at risk for 1 year. Relative risk ratio is the ratio of the incidence rate in the exposed group to the incidence rate in the nonexposed group. Specific rates are detailed rates that are calculated using the number of people in the smaller subgroups of the population in the denominator.
