When conducting research, it is hardly ever possible to study the entire population that you are interested in.For the latter reason, convenience samples are commonly used in the early or pilot stages of research, before a larger research project is launched.A convenience sample is a non-probability sample in which the researcher uses the subjects that are nearest and available to participate in the research study.A convenience sample also has the benefit of allowing for a low- to no-cost research study to be conducted, because it uses the population that is already available.
