Convenience sampling
Sampling from the part of the population close at hand / From Wikipedia, the free encyclopedia
Convenience sampling (also known as grab sampling, accidental sampling, or opportunity sampling) is a type of non-probability sampling that involves the sample being drawn from that part of the population that is close to hand.

Convenience sampling is not often recommended by official statistical agencies for research due to the possibility of sampling error and lack of representation of the population.[1] It can be useful in some situations, for example, where convenience sampling is the only possible option. A trade off exists between this method of quick sampling and accuracy. Collected samples may not represent the population of interest and can be a source of bias, with larger sample sizes reducing the chance of sampling error occurring.
