O método RAJAR (GB)

(e os problemas na medição de audiência)

«Understandably, measuring radio audiences is complicated: radio can be listened to virtually anywhere and there are literally hundreds of station areas to survey. The cost to the radio industry for this service is almost £4 million a year. RAJAR produce listening figures every three months based on the the response from 3,000 selected respondents who each compile a seven-day diary of their listening habits. While this may seem a time-consuming and old-fashioned method of measuring audiences, because radio is listened to in a variety of locations it is still felt to be the most reliable. Several types of radio-meters are being developed, but because they require respondents to carry or wear the meter at all times, their effectiveness is still in doubt". (Fleming, 2002: 15)
