Symmetrics Sampling

Symmetric provides sampling services to companies that place a very high value on representative samples, scientific sampling methods and advanced fraud-detection systems. Symmetric applies advanced technology and sophisticated systems to create and manage some of the best online panels in the world. From its origins in 1996, Symmetric's suite of online panels have expanded to include American Consumer Opinion® and five B2B panels. All are carefully balanced, continually refreshed, and systematically cleaned via high-tech and low-tech methods. Nonresponders, speedsters, and cheaters are continually purged. In addition to its worldwide panels, Symmetric can supplement its samples by drawing participants from hundreds of other sampling sources, using the Icion® sampling platform. All samples are vetted by Symmetric's Sleuth™ fraud-detection systems. Stratified sampling controls and random selection of participants within each cell help ensure that each sample is as representative as possible.
