On the 3rd of this month I received a letter from Arbitron's president William Kerr with new dollar bill inside to take part in an upcoming survey.
Is this buying a vote? Or is it paying for a service?
Doesn't seem kosher to me; but hey what do I know about ratings?
Are you in the 6-county Seattle metro survey area (Island, King, Kitsap, Pierce, Snohomish, Thurston)? In that case your household would be recruited for being on the PPM... the letter is to make future contact less of a surprise. If it's a diary survey, you would be called or offered an Internet option to be part of the one-week process... again, for your whole household.
The money is an incentive, not a bribe.
$1 with an "advance notice letter" is standard. It's done for the guilt factor, just like the mailing labels the charities "give" you... you feel bad if you use the labels and don't send a donation.
When a person is actually recruited (that is, they call and get demographic data on the whole household) they send the diary packs to each person with $2, $5 or even $10 in each one, and the money is based on testing on what it takes to get a desirable return rate. The harder it is to get a group to participate, the more they send.
In PPM, the more consistently you carry the meter and the more compliant the household is, the more rewards the family obtains. Since the meters can stay in a compliant household for up to 24 months, the system is different.
At all times, Arbitron is very clear to the diarykeepers that they should not vote for stations and if they don't listen to the radio, they should not change any behaviour during the survey.
