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.
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%.

We were very pleased with the work done and impressed with the quick turnaround of the job on a very tight deadline...I would use B2B International again.
The research was thoroughly conducted and all the project objectives were exceedingly met.
