Sample consistency is critical to quality research. End users are aware of the data quality issues the industry is facing and are now looking for proof of 'quality' and 'consistency' in their sample. We must identify changes in our data from shifts in our sampling frame. The Sample Source Auditors test sample sources regularly for consistency.
We provide the following recognition for those participating in the Grand Mean Project® and for those that prove consistency over time:
|
|
Bronze Certification is awarded to sample sources that participate in the Grand Mean Project™ and whose data is of sufficient quality to be included in the calculation of the Grand Mean.
|
|
|
Silver Certification is awarded to sample sources who prove consistency over a three or more wave Consistent Track™ audit program.
|
|
|
Gold Certification is awarded to those companies that attain Consistent Track™ excellence by successfully completing a multi-year consistency program.
|
|
|
Seal of Consistent Excellence is awarded to a sample source that has emulated the Grand Mean and has been determined suitable for tracking studies through its long term commitment to excellence by application of the Consistent Track™ program, and the Grand Mean Project™, as well as other extensive quality measures (i.e. Optimum Blending Solutions™, as well as other proprietary solutions).
