GLOSSARY

What is split test? (A/B test)

DEFINITION

A split test shows different visitors different versions of a page or headline and compares what they do. It measures behaviour but does not explain why a version won.

Fix the sample size before you start and do not stop early. Evan Miller documents that stopping the moment a result looks significant can produce a false positive 26.1% of the time in a worst case.
