A/B Testing Calculator
Find out if your A/B test results are statistically significant
What is A/B Testing?
A/B testing (split testing) is one of the most powerful tools for a data-driven business.
A/B testing lets you compare several versions of a web page in order to discover which one is most effective for your audience. However, in order to be confident about your test results they need to be statistically significant.
Our A/B Test Calculator makes it easy to find out when your results are statistically significant. To analyze your test, simply enter the number of visits and conversions for each of your variations and click "Calculate".
A test variation can be declared a winner when its statistical significance (confidence level) is above 90%.
