Respuesta :

Answer:

Probability sampling.

Explanation:

Probability Sampling is a sampling method whereby sample from a bigger population are chosen through the use of probability theory. For a participant to be chosen as a probability sample, he or she must be chosen through a random selection. The most vital requirement in probability sampling is that everyone should have an equal chance of being selected e.g. if there is a population of 200 people, everyone involved will have an odd of 1 in 200 to be selected.

Probability sampling provides the best chance to get a sample that truly represents the population.
