# A/B Test Analysis
## Overview
A/B testing is a statistical method to compare two variants and determine which performs better, enabling data-driven optimization decisions.
## When to Use
- Comparing two versions of a product feature, webpage, or marketing campaign
- Optimizing conversion rates, click-through rates, or user engagement metrics
- Making data-driven decisions with statistical confidence about changes
- Determining sample size requirements for experiment validity
- Analyzing treatment effects and measuring lift from interventions
- Evaluating whether observed differences are statistically significant
