Quizplus · Accepted Answer

A telephone interview can collect either primary or secondary data, depending on the questions asked and the purpose of the interview. A follow-up interview to the same customer would also typically collect primary data, as it is based on direct interaction with the customer. Secondary data, on the other hand, refers to information that is already existing and available through sources such as published reports or databases.
