When students first enter analytics, the subject can look bigger than it really is. The right way to learn it is one small idea at a time.
Chapter Overview
A/B testing compares two versions of an experience to see which one performs better. In analytics, this is a practical way to test ideas instead of relying on opinion.
Basic Structure
Version A is the control and version B is the variant. Users are split between them, and the team tracks a success metric such as click rate, signup rate, or purchase conversion.
Student Example
Imagine testing two button labels on a signup page. One says “Start Free Trial” and another says “Create Account”. The analyst checks which label improves conversion.
Why It Matters
A/B testing teaches evidence-based decision-making, which is a core skill in product and growth analytics.
