Document Summary
Political polling is one of the most viable uses of survey sampling. The key to generalizing from a sample to a larger population is probability sampling, which involves the important idea of random selection. Social research as a whole is both art and science, sampling leans towards science. Form of sampling based on probability sampling, this technique involves the selection of a random sample . Probability sampling remains the primary method for selecting large, representative samples for social science research. Used in situations that don"t permit kinds of probability samples used in large-scale surveys (example: homeless people; there"s no list of homeless people) Non-probability sampling: any technique in which samples are selected in some fashion not suggested by probability theory (examples: purposive, snowball and quota sampling) Relying on available subjects, such as stopping people at a corner (risky method) This method doesn"t allow control over the representative ness of a sample.
