Which type of questions allow very little freedom in how they may be answered?

Closed questions are designed to elicit specific, limited responses, typically requiring a simple answer such as "yes," "no," or a choice among predetermined options. This structure significantly restricts the respondent's ability to elaborate or express personal opinions, making it easier to quantify the responses for analysis.

In contrast, open questions encourage more expansive answers and invite respondents to share their thoughts and feelings in greater detail. Leading questions are formulated to guide respondents toward a particular answer, while focus questions are aimed at narrowing the discussion to a specific topic without imposing restrictions on how the topic is explored. Therefore, closed questions stand out as the type that allows the least freedom in responses.
