Set-Top Box Lexicon: Common Measurement Language -- Averages and Proportions

CIMM is taking a pro-active role in advancing new media nomenclature and processes with both its Lexicon (terms and definitions associated with Set-Top Box data measurement) and Asset Identification Primer (glossary of asset terms). These documents form the basis of the Word-A-Week column which offers a common language for Set-Top Box nomenclature that can expedite the roll-out of the data for its many industry applications. 

It's not just the buying and selling of time and eyeballs that makes a marketplace. Metrics must be used to measure the quality and quantity of the audiences. For the last two weeks, we provided some of the terms that were common to both the current ad sales marketplace and to the STB and Addressable Advertising arena. (Set-Top-Box Lexicon: Common Commercial Terms) This column explores some of the common audience measurement terms that can be used by all these platforms focusing on "Averages" and "Proportions":
