Since 1978, the mission of Sigma Validation has been to uphold the integrity of respondent-level data being collected in consumer research studies.

We continue to maintain our mission through offering services that will help research professionals to identify potentially data-corrupting issues in traditional and online quantitative and qualitative research.

To further assist and empower our clients, we are now providing access to relevant industry presentations, articles and "Tips of the Trade."  We feel this information will provide actionable knowledge that will enhance the quality of research at its roots -- the respondent input level.
