From statistical considerations the preference is given to probability sampling over non-probability sampling.

Question

Quizplus · Accepted Answer

Probability sampling ensures that every member of the population has an equal chance of being selected for the sample, which makes the sample more representative of the population and minimizes the risk of bias. Non-probability sampling methods do not have this property and may result in a biased or unrepresentative sample. Therefore, statistically speaking, probability sampling is preferred over non-probability sampling.
