What term refers to a list of all eligible sampling units for a given study?

The term that accurately describes a list of all eligible sampling units for a given study is the sampling frame. The sampling frame serves as a comprehensive representation of the population from which the sample will be drawn. This framework is crucial because it ensures that every member of the target population has a chance of being selected, which strengthens the representativeness and validity of the research findings.

The sampling frame can consist of various elements, such as a list of individuals, households, or organizations, depending on the context of the research. It is essential for researchers to have a well-defined and inclusive sampling frame to minimize bias and ensure that data collected reflects the broader population accurately.

While a sampling plan refers to the strategy for selecting the sample and the sample size indicates how many units will be included in the study, these concepts are distinct from the idea of a sampling frame, which is specifically the list of units eligible for sampling. A population list could imply a similar notion, but it is not the standard terminology used in research methodology. Thus, the sampling frame is the most precise term in this context.
