Maru/Blue Sample Certified is designed to ensure quality sample in markets where the company does not have its own panels. Sample vendors who pass the certification programme will become preferred suppliers.

Managing Director of Maru/Blue, Rob Berger (pictured), said: “In an effort to provide reliable, consistent, quality sample to our clients in markets with no Maru/Blue-owned panels, we have built a global quality certification programme. Sample Certified tests and certifies sample vendors in countries where there is high demand for multi-market insights.”

The company has tested 14 high demand international markets: Australia, Brazil, China, France, Germany, India, Italy, Japan, Mexico, Russia, Singapore, South Africa, Spain and Thailand.

Andrew Grenville, chief research officer, designed the methodology by comparing survey results to what has been measured in censuses, household studies conducted by statistical agencies and other reliable data sources.  It also measures test-retest reliability to ensure quality that is Sample Certified.

No exchange, river or social media sources will be included in the certification programme.
