Sampling frame definition – UGC NET Question

A sampling frame is a practical list or representation of all units in the population that can potentially be selected for the sample, such as a roster of students or a registry of schools. It operationalises the population for sampling purposes. The quality of the sampling frame strongly affects the representativeness of the sample. Because the stem describes a complete list of sampling units from which the sample is drawn, sampling frame is the correct term.

Option A:
Population denotes the entire set of individuals or units to which the researcher wishes to generalise findings, but it may exist conceptually without a concrete list. A sampling frame is a specific listing used to select sample elements. Therefore, population does not precisely match the stem’s description.

Option B:
A sample is the subset of units actually selected from the sampling frame for study, not the list from which they are chosen. The stem focuses on the list itself, so sample is not the right completion.

Option C:
Sampling frames are crucial for probability sampling, as they determine whether every population element has a known chance of selection. Incomplete or biased frames can lead to coverage error. This role corresponds exactly to the description in the question, confirming sampling frame as the appropriate answer.

Option D:
Cluster refers to naturally occurring groupings within the population, such as schools or villages, which may be sampled in cluster sampling designs. It is not the same as the comprehensive list of units used in selection. Hence, cluster is not the correct term here.
