In survey research, a sampling frame is best described as:
Correct answer: A. A list of population units available for selection
- A. A list of population units available for selection
- B. A formula for calculating the sample variance
- C. A statement of the research hypothesis
- D. A table showing the final survey results
Explanation
A sampling frame is the operational list or source from which the sample is drawn. It should represent the target population as completely and accurately as possible.
Report an error
The more specific you are, the faster it gets fixed. A source beats an opinion.

About Sampling and Estimation
Sampling covers population and sample, sampling frames, simple random, systematic, stratified, cluster and convenience methods, along with sampling and non-sampling errors. Estimation includes sample statistics, population parameters, point estimates, confidence intervals and margins of error, with attention to how sample size affects precision.
