Definition
A/B Testing is a controlled experiment that compares a control variant against one or more treatments to measure causal impact on a target metric.
Core Principles
- Randomly assign users to variants
- Change one meaningful variable at a time when possible
- Predefine primary and guardrail metrics
- Run long enough to reach adequate sample size
- Analyze results with statistical rigor
