Random digit dialing is a technique used to increase the representativeness of the sample in telephone surveys. It ensures that every possible phone number in a given area has an equal chance of being selected, which minimizes sampling bias and makes the sample more representative of the population. This can improve the accuracy and generalizability of the findings.
