Choose numbers stratified random sampling-the population is divided into subpopulations called strata and random samples are drawn from each of these strata. Can take an equal number of people from each strata. Can determine each group"s proportion in the population and take that many people from each strata survey methods. Pros: quick, lack of interviewer bias, sensitivity of topic. Cons: questions have to be self-explanatory, no control of order of answers, response rate bias.
