Cicarelli then prepared a questionnaire for current and potential listeners.The questionnaire contained a long list of yes/no questions on whether the respondent listens to a specific station.The data were collected via telephone with 1,000 radio listeners using random-digit dialling.Cicarelli chose telephone interviewing because previous research has shown that nearly 100 percent of radio listeners have telephones,and it is faster than mail surveys.
