A/B Testing
experiments
You shouldn't need an enterprise Optimizely subscription to run a simple A/B test. BuddyStat's Experiments dashboard gives you variant comparison, statistical significance, and winner detection — all included.
Send a single
experiment event from your code — name your experiment and which variant the user saw — and BuddyStat handles the rest. Per-variant impressions, conversions, and conversion rates are shown in a clean comparison table.The built-in chi-squared test with Yates' correction runs continuously. When a variant reaches 95% confidence, it's automatically marked as the winner. No manual calculations, no guesswork — just clear answers about what works.

Getting Started
How it works
- 01
Set up your experiment
Create your A and B variants in your app. Add `buddystat.event('experiment', { experiment: 'my-test', variant: 'A' })` to your code to track which variant each user sees.
- 02
Define your conversion event
Choose which custom event counts as a successful conversion. This could be a purchase, form submission, button click, or any other event you're already tracking.
- 03
Let data accumulate
BuddyStat automatically collects impressions and conversions for each variant. The chi-squared test runs continuously, comparing variant performance.
- 04
Read your results
Open the Experiments dashboard to see which variant is winning. When a variant reaches 95% statistical significance, it's marked as the winner. Deploy the winner with confidence.
