Show answer & explanation
Correct answer: A
Concept
Non-probability sampling does not select every unit through a known random mechanism. Its methods are distinguished by the rule used to choose units.
In judgment sampling, also called purposive sampling, units are deliberately chosen because the researcher or an expert considers them suitable for the study.
Application
The stem says that sampling units are selected on expert advice or according to the researcher’s own opinion. That selection rule is the defining rule of judgment sampling.
Contrast
Judgment sampling: units are deliberately selected through informed expert or researcher judgment.
Snowball sampling: existing participants refer or recruit further participants.
Quota sampling: category targets are fixed and units are selected until those quotas are filled.
Convenience sampling: readily accessible units are selected because they are easy to reach.
Therefore, the sampling method described is judgment sampling.
