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.

At Notion, we're continuously learning what our users value and want every team to run experiments to learn more. It’s also critical to maintain speed as a habit. Statsig's experimentation platform enables both this speed and learning for us.

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.
