Correct Answer Explanation
The Sampling Frame refers to all the sampling units of the population — i.e., the complete list of all units from which the sample is to be selected. In random sampling, all units in the sampling frame get an equal chance of being included.
Key Points:
- Example: All 300 households in a locality form the sampling frame when selecting 30 for a survey.
- A well-defined sampling frame is essential for unbiased random sampling.
- An incomplete or inaccurate sampling frame leads to sampling bias.
- Sampling frame is the operational definition of the population for sampling purposes.
