Document Summary
Sosc 3993 chapter 7 qualitative and quantitative sampling. Sample: a smaller set of cases a researcher selects from a larger pool and generalizes to the population. Tend to use sampling based on theories of probability from mathematics (probability sampling) Census: an attempt to count everyone in a target population. Qualitative researchers focus on how the sample or small collection of cases, units or activities illuminates key features of social life. The purpose of sampling is to collect cases, events or actions that clarify and deepen understanding. Nonrandom sample: a type of sample in which the sampling elements are selected using something other than a mathematically random process. This means that they rarely determine the sample size in advance and have limited knowledge about the larger group or population from which the sample is taken. Selects cases gradually with the specific content of a case determining whether it is chosen. Haphazard sampling: get any cases in any manner that is convenient.
