Incidence rate (market research)

Incidence rate (IR) in market research is a measure for the rate of occurrence or the percentage of persons eligible to participate in a study. For example, in a study of American washing machine owners, if the eligibility of research is defined as owning a washing machine then the IR will be the percentage of Americans who own a washing machine.
