= Survey Frames = In survey methodology, a '''frame''' is the set of records from which a [[SurveyStatistics/Samples|sample]] is drawn. <> ---- == Definition == AAPOR recognizes four types of frames: 1. List frames 2. Address-based frames 3. Random-digit dial telephone frames 4. Probability-based panel frames This does purposefully exclude the statistics of non-probability web panels. ---- == List Frames == A '''list frame''' is simply a list of specifically-named individuals. Generally, if a list frame is available, it is assumed to be the population. Frame over- and under-coverage assumptions should be examined. ---- == ABS Frames == '''Address-based samples''' ('''ABS'''), or address-based frames, are lists of specific addresses without the specific individuals who are believed to live there. ---- == RDD Frames == '''Random-digit dial''' ('''RDD''') frames are randomly-selected telephone numbers. This is inherently a [[SurveyStatistics/Samples|sample]]. '''Dual-frame RDD''' ('''DFRDD''') refers to drawing two random samples for landline teleophone numbers and cellphone numbers, respectively. ---- == Probability-based Panels == ---- CategoryRicottone
