What is difference between probability and nonprobability sampling?
The difference between nonprobability and probability sampling is that nonprobability sampling does not involve random selection and probability sampling does. In general, researchers prefer probabilistic or random sampling methods over nonprobabilistic ones, and consider them to be more accurate and rigorous.
