A good questionnaire should be

• A. Short and simple
• B. Unclear and leading
• C. Balanced mix of open and closed questions
• D. Very long and full of jargon

Answer: (C)

A good questionnaire works best when it combines both closed and open questions. Closed questions give clear, easy-to-analyze bits of data because respondents choose from predefined options, which makes it simple to compare responses and quantify results. Open questions, on the other hand, invite explanations, reasons, and suggestions, yielding richer insights that reveal why people think or feel a certain way. A balanced mix leverages the strengths of both: you get reliable, comparable numbers from the closed questions and meaningful context from the open ones, helping you understand not just what people think but why. If a questionnaire is only short and simple, you might miss important details; if it’s unclear or leading, responses become biased; and if it’s very long with jargon, people won’t complete it. So, combining open and closed questions is the best approach.
