SEQUENTIAL A/B TEST CALCULATOR

Plan and analyze sequential A/B tests with this free calculator brought to you by the optimization team at Search Discovery.

Sequential test designs allow experimenters to analyze data while the test is running in order to determine if an early decision can be made. Done incorrectly, this is known as “peeking” and increases the risk of false positive/negative errors. Control your errors and run tests efficiently with this R-based calculator.
