Queston 8 – Why doesn Bridge Ratings measure Average Quarter Hour estimates?
Answer – Bridge Ratings’ results are based on solid research principles. Average quarter hour has been shown to be an extrapolation of listening. It is calculated as a function of listener estimates of the length of their listening occasions multiplied by the station’s estimated cume. Bridge Ratings pledges to deliver the most accurate numbers in audience measurement. Therefore, no average quarter hour estimates are provided. We provide Cume Share and Favoriteness data. Cume share is the station’s cume audience as a percentage of all persons listening to radio for a specific day part.
