What is a defining feature of structured interviews?

A defining feature of structured interviews is the use of a standardized set of closed questions. This consistency in questioning allows for the systematic collection of data, which is essential for quantitative analysis and comparison across different interviews. By employing a specific set of predetermined questions, researchers ensure that every participant has the same opportunity to provide responses, minimizing variability that could arise from differing question phrasing or topics covered. This approach enhances the reliability and validity of the data collected, making it easier to draw conclusions and identify trends within the research context.

In contrast, options such as a flexible question set, no predetermined questions, and open dialogue being encouraged reflect characteristics found in other interview types, such as semi-structured or unstructured interviews, which prioritize adaptability and participant-driven discussion over standardization.
