Arbitron PPM Weeklies data for December 2008 Week 2, originally scheduled to release today at 12:00 Noon local time, has been rescheduled to release this coming Thursday, 12/18, at 12:00 Noon local time in all PPM markets. Arbitron has discovered that in some instances, panelists during December Week 2 (11/20-11/26) who may not have met all criteria for in-tab eligibility initially appeared to be eligible. During preliminary data processing, they discovered that a limited number of panelists who had not met the minimum daily motion requirement (i.e., the requirement that panelists wear or carry their meters for a specified number of hours during the survey day) had been inappropriately entered into internal files as having met the requirement.
