Random-digit dialing is a technique used to overcome the bias of unpublished and recent telephone numbers. In this technique, all telephone number digits are selected at random, which helps to ensure that the sample is representative and not biased towards any particular group. Systematic dialing, cluster dialing, quota dialing, and speed dialing are other types of sampling techniques used in phone surveys, but they are not specifically designed to overcome the bias of unpublished and recent telephone numbers.
