What is non-probability sampling ?
In non-probability sampling, those who take part in a study are chosen not at random but rather because of some circumstance that provides them an opportunity to take part that other members of the population do not.
(A) Cluster sampling : In cluster sampling, a population is divided into clusters, which are smaller groups. They then choose a sample at random from these clusters.
(B) Judgemental sampling: A non-probability sampling method where the researcher chooses the sampled units based on his own prior information or his expert judgement.
(C) A probability sampling method where researchers select members of the population at a regular interval.
(D) Snowball sampling: A non-probability sampling method in which current study participants find new study participants from their experience.
(E) Quota sampling: A sampling technique that gathers information from a homogeneous group.
