Which of the following statements refers to a sampling frame?

AA comprehensive coverage of the stages involved in designing a survey

BA summary view of all the main clusters of units in a sample

CA list of all the units in the population from which a sample will be selected ✓ Correct

DA table used to display random numbers

Correct answer: (C) A list of all the units in the population from which a sample will be selected

Explanation

A sampling frame is the list of all the units in the population from which a sample is selected.

A comprehensive coverage of survey design stages describes the research plan, not the frame.

A summary of the main clusters is only a partial view and misses the full unit list.

A table of random numbers is a selection tool, not the listing of population units.

Gaps or duplication in the frame cause coverage error in the sample.

The quality of the sampling frame directly limits how representative the sample can be.
