Check the statistical significance for results of an A/B marketing test that has been completed. This calculator will tell you the percentage confidence you can have in the difference between A and B results not being just down to chance.

Enter your percentage responses for the A and B sample results and the sample size.

  1. A and B sample response rates can be a percentage measure of any metric; typically open rate, click rate or conversion rate. Enter values between 00.00 and 100.00.
  2. The sample size should be number of people in one of the samples. It is assumed A and B samples are the same size.
