Quizplus · Accepted Answer

Snowball sampling is a technique where participants are recruited through referrals from other participants who belong to the difficult-to-access population. This technique is useful for reaching populations that are difficult to identify or locate, such as drug addicts, homeless people, or illegal immigrants. Availability sampling is a technique where participants are selected based on their availability at a given time and place, which is not applicable in this scenario. Simple random sampling and probability sampling, on the other hand, are techniques used to obtain a representative sample from a larger population, which is not the aim of snowball sampling.
