Random digit dialing is the most common method used to select respondents for a telephone survey. It involves generating phone numbers randomly to ensure a representative sample of the population. Using telephone books or opt-in lists may introduce bias as they only include certain segments of the population. Records provided by wireless phone companies may also be incomplete or biased. It is not illegal to select samples via telephone unless certain regulations are violated, such as the national Do Not Call registry.
