Detailed explanation-1: -This is one of the most common forms of non-probability sampling. Sampling is done until a specific number of units (quotas) for various subpopulations have been selected.
Detailed explanation-2: -Snowball sampling or chain-referral sampling is defined as a non-probability sampling technique in which the samples have rare traits. This is a sampling technique, in which existing subjects provide referrals to recruit samples required for a research study.
Detailed explanation-3: -In non-probability sampling, the sample is selected based on non-random criteria, and not every member of the population has a chance of being included. Common non-probability sampling methods include convenience sampling, voluntary response sampling, purposive sampling, snowball sampling, and quota sampling.
