Which of the following is a characteristic of a good questionnaire?

• A. Clear and simple questions without jargon
• B. Balance open and closed questions
• C. No leading questions
• D. Short

Answer: (B)

A good questionnaire should gather both measurable data and detailed feedback, so the best characteristic is balancing open and closed questions. Closed questions provide quick, easy-to-analyze numbers and allow easy comparison between respondents. Open questions invite respondents to explain their thinking, share experiences, and reveal motivations or issues you might not have anticipated. Together, they give reliable statistics plus rich insights, making the data both scalable and meaningful. If you relied only on closed questions, you’d miss the reasons behind answers; if you used only open questions, analysis would be more time-consuming and harder to compare. Clear wording and avoiding leading questions are important too, but the balance of question types is what makes a questionnaire most effective.
