Probability sampling refers to the process of selecting a sample from a population where each member of the population has a known and non-zero probability of being selected. This ensures that the sample is representative of the population and can be used to make valid statistical inferences. Other sampling methods, such as nonprobability sampling, purposive sampling, convenience sampling, and judgment sampling, do not guarantee the same level of representativeness and may introduce bias into the sample.
