Does it recommend specific testing tools?

The skill provides implementation guidance for popular experimentation platforms such as PostHog, Optimizely, VWO, and LaunchDarkly for both client-side and server-side setups.

How does this skill help with statistical significance?

It provides pre-calculated sample size references and guidance on confidence intervals (p-values) to ensure your results are statistically valid and not due to random chance.

What is the 'peeking problem' mentioned in the skill?

The peeking problem occurs when you stop a test early because you see a preliminary result. This skill helps avoid false positives by committing to a pre-determined sample size.

Can I use this for multivariate testing (MVT)?

Yes, the skill covers various experiment types including A/B, A/B/n, and multivariate testing (MVT), providing context on when to use each based on your traffic volume.
