Judgmental Sampling Definition<\/h2>\n

Judgmental sampling, also called purposive sampling or authoritative sampling, is a non-probability sampling technique in which the sample members are chosen only on the basis of the researcher’s knowledge and judgment. As the researcher\u2019s knowledge is instrumental in creating a sample in this sampling technique, there are chances that the results obtained will be highly accurate with a minimum <\/span>margin of error<\/span><\/a>. <\/span><\/p>\n

The process of selecting a sample using judgmental sampling involves the researchers carefully picking and choosing each individual to be a part of the sample. The researcher\u2019s knowledge is primary in this sampling process as the members of the sample are not randomly chosen. <\/span><\/p>\n

When to execute Judgmental Sampling?<\/h3>\n

Judgmental sampling is most effective in situations where there are only a restricted number of people in a population who own qualities that a researcher expects from the target population. Researchers prefer to implement Judgmental sampling when they feel that other sampling techniques will consume more time and that they have confidence in their knowledge to select a sample for conducting research. <\/span><\/p>\n

Judgmental or Expert sampling is usually used in situations where the target population comprises of highly intellectual individuals who cannot be chosen by using any other <\/span>probability<\/span><\/a> or <\/span>non-probability<\/span><\/a> sampling technique. It is also used in situations where the sample selected using other sampling methods need to be approved or filtered. For instance, in situations where a researcher conducts <\/span>convenience sampling<\/span><\/a> to gather feedback from professors about their university but the fact that there are high chances of the results to be skewed, researchers prefer judgmental sampling to select those professors who will provide 100% feedback about the university.<\/span><\/p>\n

Selecting each individual of the sample is a critical challenge that an intellectual researcher will undertake. It is a tedious task to handpick members of a sample while ensuring there is no bias involved. <\/span><\/p>\n

The authority involved in the selection process may not necessarily be \u201cexperts\u201d in the field but they have to comply with certain characteristics expected from a Judgmental sampling authority and sampling errors<\/a>. Education or work experience is not considered while appointing authorities for the selection process. <\/span><\/p>\n

Purposive sampling is used where there is time-constraint for sample creation and the authorities involved would prefer relying on their knowledge and not on other <\/span>sampling methods<\/span><\/a>. But, one must keep in mind, the fact that a researcher may or may not have the appropriate proficiency to conduct an effective sampling process. This is the only disadvantage of purposive sampling<\/a>. Each researcher who takes up the responsibility of creating a sample using expert sampling will have to be extremely confident in their own skills and understanding of the subject.<\/span><\/p>\n
