Bias compensating remote audience survey system and method
First Claim
1. In a remote audience survey system, a method of compensating for a station bias, said survey system being configured to identify radio stations to which tuners are tuned, said tuners having predetermined signals emitted therefrom, and said method comprising the steps of:
- measuring durations during which a portion of said predetermined signals are received by said survey system, said portion of said predetermined signals describing one of said radio stations;
combining said durations to form a characteristic detection statistic for said one radio station; and
adjusting a sensitivity level to provide an amplitude threshold for said one radio station in response to said characteristic detection statistic to compensate for said station bias prior to collecting survey data.

Abstract
A bias compensating remote audience survey system (34) is configured to identify radio stations (162) to which tuners (24) are tuned. The tuners (24) have predetermined signals (26) emitted therefrom. The survey system (34) employs a method (152) of compensating for a station bias, or preference, toward or against one or more of radio stations (162). The method (152) includes measuring durations (62) over which the predetermined signals (26) are received by the survey system (34). The durations (62) are then combined by averaging to form a station average detection length (ADL) value (74) specific to one of the radio stations (162). The station ADL value (74) is compared to a multi-station ADL parameter (86). A sensitivity level (146) for the one radio stations (162) is adjusted in response to the comparison to compensate for station bias.
