In a community survey, the ASHA worker records nutritional status of all children in her village. This sampling method — including all members of the accessible population — is termed:

• A Cluster sampling
• B Census (complete enumeration) ✓
• C Purposive sampling
• D Convenience sampling

Explanation

When every individual in the accessible population is included without any sampling, it is termed a census or complete enumeration. Cluster sampling involves randomly selecting groups (clusters) and surveying all members within selected clusters. Purposive sampling selects individuals based on specific characteristics. Convenience sampling takes whoever is easily accessible. For small populations like a village, complete enumeration is feasible and eliminates sampling error, though it cannot be generalized to other populations as a sample would be.
