Answer to Question 1

Ans: C
Feedback:
Prevalence rate is the measure of the number of people in a given population who have an existing condition at a given point in time. Adjusted rate is the statistical procedure that removes the effects of differences in the composition of a population, such as age, when comparing one with another. Incidence rate is the measure of the probability that people without a certain condition will develop that condition over a period of time. Specific rates are detailed rates that are calculated using the number of people in the smaller subgroups of the population in the denominator. Often people are divided into subgroups by age and sex, although any characteristic can be used.
