Media-Tainted Diaries Prompt Revised San Diego Arbitrends
September 26, 2008 at 12:44 PM (PT)
ARBITRON has discovered that three SUMMER 2008 Week 2 SAN DIEGO metro diaries were returned from a media-affiliated household. The diaries, which were in-tab for the originally released Arbitrends estimates, should not have been included in the in-tab sample.
Revised SAN DIEGO Arbitrends data for the SUMMER Phase 1 Arbitrends report period (MAY-JUNE-JULY) and the SUMMER Phase 2 Arbitrends report period (JUNE-JULY-AUGUST), based on an in-tab sample that excludes these diaries, will release on FRIDAY, SEPTEMBER 26th, at 10a PT.
Audience estimates for KLSD-A may be substantially affected in particular demos and dayparts. Estimates to other stations may be slightly affected, as a result of sample balancing and reprocessing procedures that accompany deletion of any diary from the sample.
