Survey Frame
A survey frame is a list used for survey sampling.
Description
AAPOR recognizes four types of frames:
- List frames
- Address-based frames
- Random-digit dial (RDD) telephone frames
- Probability-based panel frames
This does purposefully exclude the statistics of non-probability web panels.
The details of a frame establish the universe for survey inference.
List Frames
A list of specifically-named individuals.
List frames are commonly taken as a complete population. Assumptions about over-coverage and under-coverage should be examined.
ABS Frames
A list of specific addresses; the specific residents are not necessarily known, nor whether they are eligible.
RDD Frames
A procedure for randomly generating telephone numbers.
Dual-frame RDD (DFRDD) refers to drawing two random samples for landline telephone numbers and cellphone numbers.
