Question

How can we reduce the rate of refusals in telephone surveys? Mostpeople who answer at all listen to the interviewer'sintroductory remarks and then decide whether to continue. One studymade telephone calls to randomly selected households to askopinions about the next election. In some calls, the interviewergave her name, in others she identified the university she wasrepresenting, and in still others she identified both herself andthe university. The study recorded what percent of each group ofinterviews was completed. Is this an observation study or anexperiment. Why? What are the explanatory and responsevariables?
