Free A/B Test Calculator

A practical guide to the science of product experiments. Learn how to distinguish real growth from random noise using a simple "basketball bus" analogy and a real-world Amazon case study. Master the basics and start making data-driven decisions today!

A/B Testing Fundamentals Guide

Stop making product decisions based on intuition. Join a virtual team at a meditation startup and learn how to test your ideas like a pro. You will evaluate a real experiment, see how randomness can trick even experienced PMs, and learn to identify when an A/B test is actually worth the effort. This is a full lesson, not a cut version.

To run A/B experiments on your product, you don’t need deep knowledge of statistics. You are a PM — you operate on a different level. You need to understand the core principles of testing.→ Why learn with me?I’ve been running A/B experiments as a product manager for 10 years. I’ve designed, launched, and took decisions on more than 1,000 experiments across different products with millions of visitors such as booking.com.I will explain exactly what the role of a PM is in a data-driven team. PMs don’t use formulas, but they need to understand the concept of statistical power — and, above all, how to test what matters most.→ What makes this course different? Practical learning!You don’t learn by watching videos or reading slides. You learn by solving real-world tasks and getting feedback on your decisions.That’s why my course is built around practice and solving cases. We are going to design experiments and make decisions.→ A/B experimentation is a skill you must haveSome product decisions can’t be made from intuition, empathy, or product vision alone. They need to be based on data. If you want to work on a big, mature product, experimentation must be part of your core toolkit.

Put your skills to practice

I will assume that you have some experience leading a product team and you are comfortable with managing backlog and the roadmap.

Basic Product Management skills

Product ManagersThis course is written by a PM for PMs, I assume basic knowledge of key product metrics such as conversion, retention etc.

PMs who want to work on large scale productsWhat to develop your career in big tech? This is a skill employers are looking for.
