Frequently Asked Questions

Check statistical significance first (usually 95% confidence). Look at the primary metric, but also secondary metrics for unintended effects. Segment results by user type — averages can hide important patterns.

Inconclusive results are still results. Options: run longer for more data, test a bigger change, or accept that this variable doesn't matter much. Document learnings either way.

Don't peek at results early, ensure adequate sample size before starting, test one variable at a time, and account for novelty effects. Run for full business cycles to capture weekly patterns.
