In which of the following sampling methods is the sample also known as an accidental sample and a haphazard sample?

APurposive sampling

BQuota sampling

CStratified random sampling

DConvenience sampling ✓ Correct

Correct answer: (D) Convenience sampling

Explanation

The sample also called accidental or haphazard is drawn by convenience sampling.

Convenience sampling takes whoever is easily available, so cases arrive by chance of access.

Purposive sampling instead selects cases deliberately for their relevance, not by accident.

Quota sampling fills preset category quotas, giving structure absent in accidental selection.

Stratified random sampling is a probability method drawing randomly within strata.

Convenience sampling is quick and cheap but weak in representativeness.
