Various advantages of sampling are as discussed below: -. As a refresher, non-probability sampling is where the samples for a study are gathered in a process that does not give all of the individuals in the population equal chances of being selected. 4 What are the advantages of purposeful sampling? Research findings can never be 100% representative of population. The same strategy can be followed to conduct research or study individuals belonging to certain underground subculture, or individuals who have a hidden identity or are members of a cult etc. Low cost of sampling If data were to be collected for the entire population, the cost will be quite high.

In order for a study to be conducted as efficiently as possible, researchers should strive to use the sample that is most relevant to their population of interest as possible. Other advantages of this methodology include eliminating the phenomenon of clustered selection and a low probability of contaminating data. The researcher may be unable to calculate the intervals and the margin of error. By proceeding from one recommendation to the next, the researchers may be able to gain a large enough sample for their project. Really Listening? What is the benefit of judging?

Efficiency: Judgment sampling is often used when the population of interest is rare or hard to find. Then, the researchers randomly select people within those clusters, rather than sampling everyone in the cluster. It can glean information from the various extremes of population groups. When researchers use the homogeneous purposive sampling technique to collect information, then they are selecting individuals who have a shared set of characteristics.
