Close-ended question means that the choice of answers on this question is limited. Close-ended questions are usually used for collecting data for a statistical survey in a structured interview.
A structured interview is a type of an interview when each interviwee is asked the same questions in the same order.
Structured interviews can also be used as a qualitative research methodology (Kvale, 1996). These types of interviews are best suited for engaging in respondent or focus group studies in which it would be beneficial to compare/contrast participant responses in order to answer a research question (Lindlof & Taylor, 2002). For structured qualitative interviews, it is usually necessary for researchers to develop an interview schedule which lists the wording and sequencing of questions (Patton, 1990). Interview schedules are sometimes considered a means by which researchers can increase the reliability and credibility of research data (Lindlof & Taylor, 2002).
