A/B Test Design Studio
A/B testing turns opinions into evidence. But poorly designed tests waste time. This exercise teaches you to design A/B tests that provide real answers. You'll learn to create solid hypotheses, meaningful variants, and achieve statistical validity.

Participants will:
- Form testable hypotheses for A/B experiments.
- Design clean variants that isolate variables.
- Calculate sample sizes and test duration.
- Plan analysis approaches that avoid common pitfalls.
- Document tests for learning.
Participants will produce:
- An A/B test design with a clear hypothesis.
- Clean variants that isolate variables.
- A statistical plan for valid results.
- Documentation for organizational learning.
Common mistakes to watch for:
Key questions to consider:
- Testing too many variables at once dilutes results.
- Stopping tests too early leads to false positives.
- Ignoring statistical significance creates uncertainty.
- Poor documentation hampers future learning.
Key questions to consider:
- Is A/B testing the right approach?
- Do we have enough traffic to get results?
- How long until we can expect results?
- What actions will we take based on each potential outcome?
