Response Accuracy Calculator

Use our Response Accuracy Calculator to assess the accuracy of your survey results, based on the size of your sample, and to 95% confidence limits.

Using the Response Accuracy Calculator

  1. Select the % figure for each response e.g. 75% respondents answered ‘yes’ to a particular question.
  2. Select the total sample size e.g. 500 completed questionnaires.
  3. The figure in the box shows the accuracy of your response.

E.g. if 75% respondents answered ‘yes’ to a particular question, and you spoke to 500 respondents, you can be 95% confident that your result is accurate within 3.9%. I.e. If you interviewed everyone in the market, you would reasonably expect a ‘yes’ response of not less than 71.1%, and not more than 78.9%.
