Since 1978, we have been proudly serving the marketing research community. We provide services that help ensure and maintain quality research standards in North America. Building a bridge to quality has been our main objective. New Generation Research Group was incorporated in 1968. In 1978, General Foods (now part of Kraft Foods), was in search of an alternative to telephone validation. They suggested and underwrote Sigma Validation, a D.B.A. of New Generation Research Group, Inc. A new kind of validation, based on the matching of respondent telephone numbers, called the Duplicate Number® Search, was born. Based on the matching of respondent telephone numbers, it helps overcome shortcomings in telephone validation. In the first quarter of 2005, Sigma Validation will be introducing the Duplicate Email™ Search, the first-ever method for helping to ensure the respondent-level quality of Internet research.
