Test duration calculator
A test duration calculator is a simple calculator that determines how long you need to run
your split test to get a reliable test result. You input data such as the existing conversion
rate, the number of variations in the test, the amount of traffic your site gets, and more.
The calculator then determines how many days to run this test to get a reliable result.
