GrowthHackingIdea - A 23.8% lift was wrong. Was yours?
Copy Hackers ran a usual A/B test. After a week, the tool declared a 23.8% lift with 99.6% confidence.
But actually, both the control and the treatment were exactly the same.
Possible reasons worth checking:
1. A tool works incorrectly.
2. Load speed of your site is slow.
3. A code was placed wrong.
4. A test was stopped too early. Significance is not a stopping factor, sample size is.
5. You acquired traffic for a test from “unusual” sources.
