This weekend workshop is a hands-on introduction to A/B Testing for data scientists and product managers. To drive real impact, you need to connect experiment results to business decisions, partner effectively with product teams, and communicate insights that shape roadmaps. This workshop helps mid-senior data professionals strengthen those skills, sharpen product thinking, and elevate how they approach experimentation.Across fast-paced case studies, group discussions, and live walkthroughs, you’ll learn to:<ol><li>Frame hypotheses that lead to clear decisions</li><li>Pick metrics that reflect real business trade-offs</li><li>Interpret results beyond statistical significance</li><li>Communicate insights to PMs, leaders, and cross-functional teams</li></ol>By the end, you won’t just run A/B tests — you’ll make better product decisions with them. We’ll close with what separates good data scientists from great ones and how to keep growing your skills.

Learn to Design and Analyze A/B Tests that Influence Product Strategy.

Master high-signal A/B test design

Build confidence in interpreting experimental results.

Apply industry case studies to real product challenges

Communicate experiment outcomes through clear decision briefs

Use a reusable A/B testing framework to evaluate and improve experiments

Level up experimentation judgment to operate like a senior data scientist.

No advanced math or statistics required. Just curiosity, a willingness to learn, and an interest in how product decisions are made.

Basic Comfort with Data and Curiosity

Data scientists who want to build A/B Testing skills to share business outcomes and get interview-ready.

Growth analysts looking to design high-impact experiments and optimize key funnel metrics.

Product Managers who work closely with data teams and want to better frame, interpret and act on experiment results.

This weekend-intensive workshop is built for data scientists who want to go beyond just “running experiments” — and start shaping product strategy through evidence-based decision-making. Over two immersive days, you’ll gain hands-on experience in designing robust experiments, analyzing results with rigor, and translating findings into measurable business impact. Through live lectures, breakout discussions, and case-based exercises, you’ll learn not just how to run experiments, but why each design choice matters — from hypothesis framing to metric selection and trade-offs. This program is fast-paced and practical, tailored for mid-level professionals who want to level up their experimentation craft and drive product outcomes with clarity and confidence.
