Probability sampling procedures involve random selection methods, which aim to ensure that every member of the population has an equal chance of being included in the sample. Thus, the results obtained from a probability sample can be generalized to the population with a known level of precision. However, to achieve this goal, the researcher must adhere strictly to the selection procedures to avoid bias and other sources of error that may compromise the representativeness of the sample. In contrast, nonprobability and non-random sampling procedures may not offer such guarantees and may be subject to various forms of selection bias and other limitations, which can affect the generalizability of the findings.
