FRAME

Statistics Directorate    
French Equivalent: Base

Definition:
A list, map or other specification of the units which define a population to be sampled.

Context:
The frame consists of previously available descriptions of the objects or material related to the physical field in the form of maps, lists, directories, etc., from which sampling units may be constructed and a set of sampling units selected. (Eurostat, “Assessment of Quality in Statistics: Glossary”, Working Group, Luxembourg, October 2003)

The frame may or may not contain information about the size or other supplementary information about the units, but should have enough details so that a unit, if included in the sample, may be located and taken up for inquiry. The nature of the frame exerts a considerable influence over the structure of a sample survey. It is rarely perfect, and may be inaccurate, incomplete, inadequately described, out of date or subject to some degree of duplication. Reasonable reliability in the frame is a desirable condition for the reliability of a sample survey based on it.
