This project now continues as GoodUI Patterns ...

To check for what changes truly repeat we needed a more scalable platform. That's why we stopped adding tests under GoodUI Evidence and built an even more powerful platform - GoodUI Patterns.

How do we set the strength of effects?

Here is how we color code the effects of each test to make it easier to separate the strong from the weak.

Strong Loser

300+ conversions and a p‑value of 0.03 or smaller

Possible Loser

100+ conversions and a p‑value of 0.25 or smaller

Insignificant

A p‑value higher than 0.25

Possible Winner

100+ conversions and a p‑value of 0.25 or smaller

Strong Winner

300+ conversions and a p‑value of 0.03 or smaller
