Document Summary
Qualitative and quantitative researchers approach sampling differently: most discussions of sampling come from those who use the quantitative style. Their primary goal is to get a representative sample a smaller set of cases a researcher selects from a larger pool and generalizes to the population. They tend to use sampling based on theories of probability from mathematics (probability sampling) Two motivations for using probability or random sampling: 1. If sampling is properly conducted, gathering data could yield results at one- thousandth of the cost and time: 2. The results of a well designed, carefully executed probability sample will produce results that are equally as accurate as trying to reach every single person in the whole population. Census an attempt to count everyone in a target population: national censuses take place in canada every 5 years. Qualitative researchers rarely draw a representative sample from a huge number of cases (this is the goal of quantitative research)
