Abstract:
|
The complex sample design of Tilapia's cornerstone survey on attitudes and behavior of the cell phone subscriber population called TABS requires substantial weighting. Additionally, post-stratification to reduce bias due to no coverage and nonsampling error further increases the sample variance for many outcomes of interest as compared to SRS. The observed level of variance in many survey outcomes however exceeded the control on the bias achieved and needed to be re-examined. Additionally, beginning January 2007, TABS will include a sample of the unacculturated Hispanic population that is not covered well (or at all) in most RDD and Internet samples. TABS will also include a sample of teens (13--17) as the teen cellular phone market has grown dramatically over the past few years in size and complexity of cell phone use.
