7 Key Elements of Good Survey Questions for Accurate Data

In this Article

In today’s fast-paced world of market research and data analysis, the quality of your survey questions can make or break your data collection efforts. Whether you’re gathering feedback from customers, conducting academic research, or checking public opinion, well-designed survey questions lead to accurate, actionable insights. But what makes a good survey question, and how can you ensure your survey is effective?

As John Zaller and Stanley Feldman explain in their study, A Simple Theory of the Survey Response, people often answer survey questions based on what’s top-of-mind at the moment, which can lead to unreliable or inconsistent data if questions are not carefully crafted. Additionally, Herbert Asher, in his book Polling and the Public, highlights the issue of nonattitudes, where respondents answer without having a genuine opinion on the subject.

This guide covers the seven essential elements of effective survey question design. By mastering these, you’ll improve your data collection accuracy and set yourself up for research success.

The Importance of Well-Crafted Survey Questions

Before diving into the essentials, it’s crucial to understand why thoughtful question design is so important. Good survey questions are the foundation of data quality, ensuring your results are accurate, consistent, and actionable.

Impact on Data Quality

  • Accuracy: Clear and simple questions reduce misinterpretation and lead to more truthful responses.
  • Consistency: Standardized questions make it easier to compare responses across participants.
  • Reduced Bias: Well-phrased questions help prevent unintended influences, such as leading questions in surveys.
  • Completeness: Well-thought-out questions encourage comprehensive answers, giving you the data you need.

Avoiding Nonattitudes for More Reliable Data

As Asher explains, nonattitudes can undermine the reliability of survey data, particularly when respondents are asked questions on unfamiliar topics. Zaller and Feldman also emphasize that question design plays a crucial role in reducing nonattitudes, as well-crafted questions ensure respondents provide thoughtful and informed answers. To avoid nonattitudes, it’s helpful to include filter questions, allowing respondents to opt out if they don’t have an opinion.

Influence on Response Rates

  • Engagement: Interesting, relevant questions keep people interested.
  • Reduced Fatigue: Short and clear questions help prevent survey burnout.
  • Positive Experience: A professional and user-friendly survey boosts credibility and makes respondents more likely to complete it.

Essential Element 1: Clarity and Simplicity

What makes a good survey question? It starts with clarity. Use plain language and avoid jargon to ensure everyone understands your questions.

Using Plain Language in Surveys

  • Opt for common words over technical terms.
  • Keep sentences short and direct.
  • Avoid complex grammar.

Example:
❌ “How frequently do you engage in activities that could be categorized as social networking?”
✔️ “How often do you use social media?”

Avoiding Jargon in Questionnaires

  • Use familiar language.
  • Define technical terms where necessary.
  • Know your audience’s level of expertise.

Example:
❌ “How would you rate the usability of our platform’s interface in terms of user experience metrics?”
✔️ “How easy is it to use our website?”

Essential Element 2: Relevance to Survey Objectives

Every question should align with your survey objectives. Avoid unnecessary questions that don’t contribute to your research goals.

Aligning Questions with Research Goals

  • Start with a clear research objective.
  • Ensure each question directly supports that goal.

Example:
❌ “What’s your favorite food, and how do you feel about our new marketing campaign?”
✔️ “How satisfied are you with our new marketing campaign?”

Eliminating Unnecessary Questions

Every question should have a clear purpose. Avoid adding questions that don’t contribute to your overall research goals.

Example:
❌ “How often do you exercise? What’s your favorite vacation destination?”
✔️ “How often do you exercise?” (if it’s relevant to your research)

Essential Element 3: Neutrality and Unbiased Phrasing

Avoid leading questions in surveys that suggest a “correct” answer. Ensure your questions are neutral and balanced.

Avoiding Leading Questions in Surveys

  • Avoid emotionally charged words.
  • Don’t assume the respondent’s experience or opinion.

Example:
❌ “How much do you agree that our customer service is the best in the industry?”
✔️ “How would you rate our customer service?”

Balancing Answer Options

Make sure your response options cover all sides and include neutral choices when necessary.

Example:
❌ “How satisfied are you with our product? (Very Satisfied, Satisfied)“
✔️ “How satisfied are you with our product? (Very Dissatisfied, Dissatisfied, Neutral, Satisfied, Very Satisfied)“

Essential Element 4: Specific and Focused Inquiries

What is a good survey question? One that focuses on a single idea. Avoid double-barreled questions that ask about multiple things at once.

One Concept per Question

Simplify data analysis and reduce confusion for respondents by focusing on one idea per question.

Example:
❌ “How satisfied are you with the quality of the product and the price?”
✔️ “How satisfied are you with the product quality?”
✔️ “How satisfied are you with the price?”

Essential Element 5: Appropriate Response Options

Choose the right response options for surveys to match your question type. Ensure options are exhaustive and exclusive.

Choosing the Right Question Type

  • Multiple Choice: Use for set answers.
  • Likert Scale: Measure opinions or attitudes.
  • Rating Scale: Compare items.
  • Open-Ended: Get detailed responses.

Example:
❌ “Please describe your experience with our product.”
✔️ “How would you rate your experience with our product?” (1-5 scale)

Ensuring Exhaustive and Exclusive Options

Make sure response options cover all possibilities and don’t overlap.

Example:
❌ “What is your age? (Under 30, 30-40, 40-50)“
✔️ “What is your age? (Under 20, 20-29, 30-39, 40-49, 50+)“

Essential Element 6: Logical Order and Flow

Organize your questions in a logical sequence. Group related questions together and use skip logic to tailor the survey experience.

Organize similar questions together to make it easier for respondents to answer.

Example:
❌ “How satisfied are you with our product? What’s your preferred payment method?”
✔️ “How satisfied are you with our product?” (in product section)
✔️ “What’s your preferred payment method?” (in payment section)

Using Skip Logic

Tailor the survey experience for each respondent by only showing relevant questions.

Example:
❌ “Do you use our product? How satisfied are you with its features?”
✔️ “Do you use our product? (Yes/No)”
→ If yes: “How satisfied are you with its features?”

Essential Element 7: Pre-testing and Refinement

Before launching, conduct a pilot survey to identify unclear questions and test the flow. Use feedback to refine your questions.

Conducting Pilot Surveys

  • Identify unclear questions.
  • Test the flow.
  • Gather feedback on how long the survey takes.

Example:
❌ Launch without testing.
✔️ Run a pilot survey with a small group first.

Iterating Based on Feedback

Use the feedback from your pilot survey to refine your questions.

To streamline the refinement process, check out our Survey Templates for pre-tested questions that follow best practices. You can also use our ChatGPT prompts for surveys to quickly revise and improve your questions based on feedback

Example:
❌ Ignore feedback from the pilot survey.
✔️ Make adjustments based on the feedback and re-test.

Common Pitfalls to Avoid in Survey Question Design

While understanding the essential elements of good survey questions is crucial, it’s equally important to be aware of common mistakes that can undermine your data collection efforts.

  • Leading Questions
  • Double-Barreled Questions
  • Ambiguous Language
  • Assuming Knowledge
  • Loaded Questions
  • Overlapping Response Options
  • Missing Response Options
  • Technical Jargon
  • Biased Scales
  • Forced Answers
  • Long and Complex Questions
  • Negative Wording

Mobile Optimization for Surveys

Mobile optimization ensures that your survey is easy to complete on any device, boosting response rates and improving data accuracy.

Tips for Mobile Optimization:

  • Keep it short: Aim for simplicity in both content and design.
  • Use mobile-friendly question types: Multiple-choice or rating scales work best on small screens.

Cultural Considerations in Survey Design

When designing global surveys, it’s important to be mindful of cultural differences.

Translate Accurately:

Avoid literal translations; instead, focus on meaning.

Consider Local Contexts:

Ensure that response options are culturally relevant.
