**A/B Test Statistical Significance, Re-Invented**

## Our Hybrid Statistics Engine combines Bayesian and Frequentist methods, calculating statistical significance with more speed and accuracy

**A/B Test Statistics**, without the Hassle

Anyone running an A/B test wants to know two things: 1) when will my A/B test be complete? 2) can I trust my results

There are two types of A/B testing statistics: **Frequentist** and **Bayesian**, but our Data Scientists found that both methods have their flaws, so they invented a **Hybrid Approach** that combines the best of both.

We then translated the output into metrics that anyone can understand:

**Smart CR%**– a ponderated conversion rate, that gives more weight to recent conversions**Confidence level**– how many times (out of 100) the same test would produce the same results**Duration estimate**– how many days until the test is statistically significant

**Test Ideas,** Trust Numbers

Using the **Hybrid Approach** to A/B testing statistics, Convertize tells you when your data has captured a real increase in conversion rate.

The **Statistical Significance Calculator** incorporates more parameters than most A/B testing tools, preventing false positives and giving you the most accurate results:

- Avoid false positives
- Never waste traffic
- See how long a test will run
