What is the primary purpose of probability sampling in quantitative methods?
What is the primary purpose of probability sampling in quantitative methods?
- To study cases that provide a great deal of central importance to the research
- To select information-rich cases for in-depth study
- To permit confident generalization from the sample to a larger population (correct)
- To focus on relatively small samples, even single cases
