A/B Split Testing Calculator

The calculator below can be used to interpret the results of a usability-oriented split (A/B) test. This is a basic scenario where you have two groups of Visitors (A & B) who each get to see one version of your website and for whom you track the number of Conversions or Goals (purchases, downloads, click-throughs, etc.).

To analyze your test, put the number of unique visitors and goals reached for each group in the text boxes and click "Calculate". If you have more than 2 groups, just click the "Add a group" button, and another row will be added to the calculator.
