One Sided Tests
A one-sided test or a one-tailed test, lets you test for a metric moving in only in one direction which you specify in advance. This tradeoff gives you additional sensitivity (or power). Learn more
Examples of this include testing for regressions in guardrail metrics and testing for a change in which only one direction has any meaningful business impact. e.g. You're less interested in detecting if new features reduce crash rates, but are very interested in learning if new features are increasing crash rates.

See what our users have to say about building with Statsig
"At OpenAI, we want to iterate as fast as possible. Statsig enables us to grow, scale, and learn efficiently. Integrating experimentation with product analytics and feature flagging has been crucial for quickly understanding and addressing our users' top priorities."
Dave Cummings
Engineering Manager, ChatGPT
"We evaluated Optimizely, LaunchDarkly, Split, and Eppo, but ultimately selected Statsig due to its comprehensive end-to-end integration. We wanted a complete solution rather than a partial one, including everything from the stats engine to data ingestion."
Don Browning
SVP, Data & Platform Engineering
"Statsig has been a game changer for how we combine product development and A/B testing. It's made it a breeze to implement experiments with complex targeting logic and feel confident that we're getting back trusted results. It’s the first commercially available A/B testing tool that feels like it was built by people who really get product experimentation."
Joel Witten
Head of Data
"We knew upon seeing Statsig’s user interface that it was something a lot of teams could use."
