Use AI for experiment design, analysis, and rollout calls without losing statistical control
3 sections · 8 lessons
Define the decision, hypotheses, power, MDE, and sample size so AI supports experiment planning without blurring what the test is meant to answer.
3 lessonsChoose the right test, read confidence intervals, and control false positives from multiple comparisons, segments, and peeking.
3 lessonsRecord the AI-assisted analysis with clear inputs, checks, outputs, and limits, then evaluate whether to ship, hold, or iterate.
2 lessonsA/B testing gets risky when AI starts helping with hypotheses, analysis, and rollout advice without clear statistical guardrails. This course shows how to keep AI useful while preserving decision quality, from defining what the experiment must answer to judging whether the evidence is strong enough to ship. It is built for analysts, data scientists, and business teams who need practical experimentation decisions they can defend.
The course covers where AI belongs in an A/B testing workflow, decision-focused hypotheses, power and sample size, assumption-aware test selection, confidence intervals, multiple comparisons, and segment traps. It also covers how to document an AI-assisted analysis and turn the evidence into a ship, hold, or iterate rollout decision.
From project managers and operators to founders, analysts, and teams adopting AI, Fenzo is for people who want to get better at the work they already do.
Anything from using AI for project planning and analysis to improving workflows, decision-making, communication, and delivery. If you can describe the skill or task, Fenzo can build a course around it.
Yes. Tell Fenzo what you do, what you’re trying to accomplish, and where you’re stuck, and Fenzo will shape the course around your role, your goals, and the work you actually have to do.
No. Fenzo adapts to your starting point, so you can begin with the fundamentals or jump straight into more advanced work.
Yes. Fenzo for Business puts the whole team on one plan — shared seats, courses you can assign, and reporting on who has finished what.
See Fenzo for BusinessYou start by describing your goal or taking a short skill benchmark. Fenzo uses that context to identify gaps and shape the learning experience around them.

What the science says
Students in lecture-only classes are 1.5× more likely to fail.
How Fenzo does it
Every Fenzo lesson is interactive. No passive reading or watching, ever.

Skill retention over time · with vs. without practice
What the science says
Offloading thinking to AI erodes the very skills you’re trying to build.
How Fenzo does it
Fenzo makes you do the thinking — guided, but never done for you.

Long-term recall · retrieval vs. re-reading
What the science says
Recalling information beats re-reading it for building durable understanding.
