back to [[Survey Sampling]] :[[Stratified Sampling]] -- [[Multistage Sampling]] -- [[Simple Random Sampling]] A geographically dispersed population can be very expensive to survey with personal interviews due to extravagant travel costs. Greater economy than random sampling can be achieved by including several respondents within a local area. It is usually necessary to increase the total sample size to achieve equivalent precision in the estimators, but the savings in cost may make that feasible. ---- [[Dick Beldin]]
