POL SCI 3 Lecture Notes - Lecture 24: Sampling Fraction, Simple Random Sample, Sampling Frame
Document Summary
Sampling usually has to do with big n. Pretend each of the 50 states has a bicameral government, and that each state has 100 senators. If we have the ability and the funds, we would gather data on all of the cases. Of course, populations aren"t always people: population of trees, population of political parties, population of high schools. Population all the cases that we"re interested in. Every 10 years, the u. s. does a census: gather data on each and every living person in the u. s. A data set on every 200-300 million people in the u. s. Can get it through non-probability and through probability. Our population is the people of the u. s. , but our sample frame is people with landlines. We could also have a frame with people with cell phones. People who don"t have a phone can"t be picked. You have to live in a household (household frame: excludes homeless people and hotels and boats.
