Show answer & explanation
Correct answer: D
Concept
Sampling methods are distinguished by the rule used to select units. Probability methods use a known random mechanism; non-probability methods may instead use access, fixed quotas, or researcher-defined relevance.
Application
Judgemental sampling means that the researcher intentionally uses informed judgement to select information-rich cases. That selection rule is purposive sampling.
Contrast
Quota sampling fixes how many units to take from specified categories.
Convenience sampling selects units mainly because they are easy to reach.
Cluster sampling selects natural groups, commonly through a probability design.
Cross-check
The Australian Bureau of Statistics states that judgement sampling is also known as purposive sampling. Therefore, the applicable value is Purposive Sampling.
