It uses the judgment of an expert in selecting cases or it selects cases with a specific purpose in mind. (b) Multi-stage sampling is an improvement over the earlier methods. Non-random sampling methods are liable to bias, and common examples include: convenience, purposive, snowballing, and quota sampling. Low cost of sampling. Convenience sampling 29. Purposive sampling of primary studies for inclusion in the synthesis is one way of achieving a manageable amount of data. Here are the advantages of adopting a convenience sampling approach: Collect data quickly: In situations where time is a constraint, many researchers choose this method for quick data collection. 1. In this approach, progression through the list is treated circularly, with a return to the top once the end of the list is passed. Another non-probability method, quota sampling also identifies strata like stratified sampling, but it also uses a convenience sampling approach as the researcher will be the one to choose the necessary number of participants per stratum. Purposive or judgmental sampling: The researcher selects the data to sample based on predefined criteria. Self-selection sampling is a type of non-probability sampling technique.Non-probability sampling focuses on sampling techniques that are based on the judgement of the researcher [see our article Non-probability sampling to learn more about non-probability sampling]. Purposive sampling can be very useful for situations where you need to reach a targeted sample quickly and where sampling for proportionality is not the primary concern. Researchers often believe that they can obtain a representative sample by using sound judgment, which will result in saving time and money.

Pros and Cons of Non-probability Sampling: There are four non-probability sampling methods. 2. Sampling ensures convenience, collection of intensive and exhaustive data, suitability in limited resources and better rapport. Convenience sampling (also known as availability sampling) is a specific type of non-probability sampling method that relies on data collection from population members who are conveniently available to participate in study. The advantages and disadvantages of purposive sampling offer significant levels of flexibility, but they also require a higher level of evidence-based techniques to prove to outside observers that there is relevance to the information collected.
