Advantages

• Training interviewers is relatively straight forward and inexpensive
• Surveys that use structured interviews can cover quite large numbers of people with limited resources because they are quick and cheap to administer
• Suitable for gathering straightforward factual information such as a persons age or job
• Results are easily quantified because they use closed-ended questions with coded answers. This makes them suitable for hypothesis testing
• Response Rate

  The large numbers who can be surveyed using structured interviews increase the chance in obtaining a representative sample of the population. Structured interviews generally have a higher response rate than questionnaires. This may be because people may find it harder to turn down a fact-to-face request, and some may welcome the opportunity to talk
• Reliability

  Structured interviews are seen as reliable because it is easy for the researcher to standardise them and control them. They can make sure each intreview is conducted in the same way.
