Document Summary

In nonprobability sampling, elements are chosen through nonrandom methods. The drawback of this strategy is that each element"s probability of being included in the samples cannot be estimated. Because of a lack of random selection, the nonprobability sampling strategy is less generalizable than probability sampling because it tends to produce less representative samples. Convenience sampling is the use of the most readily accessible persons or objects as participants in a study. The participants may include volunteers, the first 25 patients admitted to a certain hospital with a particular diagnosis, all of the people who enrolled in a certain program during the month of september. The participants are convenient and accessible to the researcher; hence the term convenience sample. The advantage of a convenience sample is that it is easy for the researcher to obtain participants. The researcher may need to be concerned only with obtaining a sufficient number of participants who meet the same criteria.
