Survey question checker
Find wording that may lead respondents, ask two things at once, or leave the task unclear. Runs local checks and offers a prompt for further review; it does not validate a questionnaire.

- Before writing your survey: adapt a complete survey template, or choose a question format using our survey question examples and 5-point and 7-point scale templates.
- Before recruiting: use the message clarity checklist to review the copy, then estimate recruitment and cost with the planner.
- After collecting responses: use the comparison calculator for two independent groups, or the margin-of-error calculator for uncertainty around one proportion.
These are planning and analysis tools. They do not recruit participants, collect survey responses, or decide which message you should publish.
