Which type of question fails to meet the clarity standard by being unclear and ambiguous?

A vague question fails to meet the clarity standard because it lacks a clear and specific meaning, making it difficult for the respondent to understand what information is being sought. Vagueness can arise from using broad terms or general concepts that do not provide enough context, leading to misunderstandings or multiple interpretations. For instance, asking "What do you think about the situation?" is vague, as it does not specify which part of the situation is under consideration or what aspect the asker is interested in.

In contrast, leading questions are designed to suggest a particular answer, argumentative questions provoke a debate or dispute, and compound questions ask multiple things at once, potentially confusing the respondent. While all these types may have their own issues, vagueness specifically centers on a lack of clarity and precision in phrasing.
