5 Common Survey Design Mistakes (and how to avoid them)

Surveys are a powerful tool for gathering insights, but small missteps in their design can lead to skewed results, disengaged respondents, or even unusable data.

Understanding these pitfalls—and how to avoid them—can make all the difference in ensuring a smooth survey experience. Client Manager, Shelley Timms outlines five most common mistakes and how to avoid them with practical examples.

Inconsistent wording between surveys

Inconsistent wording makes it difficult to aggregate responses across different surveys or track trends year-over-year. Even minor wording changes can influence how respondents interpret and answer the question, potentially skewing your data.

🚫 Don’t✅ Do
Create surveys from scratch each timeUse a template so the format and wording remains consistent
Have unclear communication during the survey development stageAssign a lead to the evaluation project to oversee consistency and proofing
Modify multiple-choice or dropdown options inconsistentlyUse pre-defined Question Bank questions or cross reference where possible

Over-using required questions

Mandatory questions in a survey can frustrate respondents, leading to higher dropout rates and lower data quality. While some required questions are necessary for logic-based flows, forcing respondents to answer every question—especially personal ones—can result in survey fatigue and discomfort.

🚫 Don’tDo
Make demographic questions like age, gender, and economic impact mandatoryOnly require questions that are essential for logic or sampling accuracy
Assume required questions improve data qualityRecognise that forcing responses can lead to inaccurate or rushed answers
Force respondents to provide feedback with mandatory questionsEncourage flexibility and the option to provide constructive feedback

Double-barrelled questions

Questions that ask about two different issues simultaneously make it unclear which part the respondent is addressing. This can confuse the respondent and make it difficult to report the results accurately.

🚫 Don’tDo
Use double-barrelled questions such as “How satisfied are you with our product quality and customer support?”Separate into two questions: “How satisfied are you with our product quality?” and “How satisfied are you with our customer support?”
Assume respondents can provide a meaningful answer to a question covering multiple issuesRecognise that splitting questions improves clarity, data reliability and comparisons

Using complex language

Using overly technical language, jargon, or complex phrasing can alienate respondents and make surveys harder to understand. Accessible language ensures that all respondents, regardless of background or literacy level, can participate and provide meaningful responses.

🚫 Don’tDo
Use language such as “It contributed to an enhanced sense of social cohesion within the community.”Use simple, relatable phrasing: “It helped me feel connected to people in the community.”
Use industry jargon or complex terminologyKeep language clear and accessible to all respondents
Assume all respondents have the same level of understanding or literacyEnsure questions are inclusive by following accessible language practices

Skipping the survey review step

Skipping the testing phase before distributing a survey can result in undetected issues like typos, broken logic, or unclear questions. A poorly tested survey can frustrate respondents and compromise data quality.

🚫 Don’tDo
Send out a survey without testing it firstPreview and test the survey internally before launch
Assume there are no errors in the logic or wordingHave someone else review the survey for clarity and functionality
Forget to use the survey platform’s test modeUse built-in preview tools to check for logic errors, typos, and technical issues
