Question

Quizplus · Accepted Answer

Probability sampling uses mathematical techniques to choose a representative subset of the population, ensuring that each member of the population has a known, non-zero probability of being selected. This is generally considered the most rigorous sampling technique and is the best choice when trying to generalize findings to the larger population. Simple random sampling is a type of probability sampling, but it is not as precise as other probability sampling techniques. Purposive sampling involves deliberately selecting specific individuals or groups that are believed to be representative of the population. Snowball sampling involves selecting participants based on referrals from previous participants and can lead to biases in the sample.
