There is no such thing in the real world of commercial radio. Advertisers in major markets buy 18-54, or some subset, and don't care about 12+
WBAP ain't going down...they are in their normal range.
It's not even in the top 15 in 25-54. That is not a normal range, and not a salable range.
[/quote] Now to Arbitron: I now recall what they do in the diary process...it is called "Weighting" in other words they give more ratings to minority stations...specifically hispanics...that is not equality...that is bias.[/quote]
Every random probability sample has to do some degree of weighting. In theory, a sample will give a perfectly proportional representation of every subset you care about in the universe you are sampling. But today, refusal rates, availablity of indivuduals, security and fraud issues cause different groups to respond out of proportion. So weighting up or down of under or oversampled cells is used to restore proportionality.
An example. A market is 55% women and 45% men. You sample 100 people and get 52% women and 48% men. The women will be weighted up to 55% and the men will be weighted down to 45% to achieve a match with the market percentage of men.
All cells by age, gender, ethnicity, language and geography, are weighted up or down to make their part in the total Arbitron sample in 100% proportion with the market composition. Weighting has been used by Arbitron since 1964 when they started doing radio surveys.
Weighting does not benefit or harm any ethnicity or age group. It is used to make the achieved sample match the universe being sampled.
KESS and other Spanish stations would not be so high and English language stations would be at normal levels. Country would be up and so would HOT AC...News/Talk too. Both Country stations will soar big time with PPM...I don't believe they are middle of the pack...this is Texas!
The PPM employs the same standard for weighting as the diary method does. As we have seen from Houston, the total Spanish shares in the PPM there are HIGHER than under the diary (19.2 to around 21 shares) and country stations are generally down. The improved formats are rock, like The Buzz, and AC, like Sunny. Urbans are about the same after the panel shook out, and AM is off overall, especially in 25-54.
