What is the main characteristic of convenience sampling?

Convenience sampling is primarily defined by selecting participants based on availability. This method involves choosing individuals who are easy to reach or readily accessible, rather than using a systematic approach or criteria that represents the larger population. This can often lead to a sample that is not representative of the overall population, which can limit the generalizability of the findings.

By focusing on availability, researchers can quickly gather data without the time-consuming processes involved in random sampling or stratified sampling techniques. This approach is often used in preliminary research or exploratory studies where the aim is to gather insights without extensive resource allocation. While convenience sampling can yield quick results, it should be noted that its limitations include potential bias and difficulties in drawing broader conclusions from the findings.
