Most teams have shipped a “winning” test that didn’t actually change anything, or worse, had a negative impact. The result looked solid, but the underlying data or setup was never trustworthy in the first place.
On July 16 (9am PT / 12pm ET), Ronny Kohavi, who wrote the book on trustworthy experiments, joins Luke Sonnet, Head of Experimentation at GrowthBook, to take apart real A/B tests that looked like wins and weren’t.
They’ll cover:
Why power calculations are non-negotiable
Reading p-values and false positive risk correctly
Detecting sample ratio mismatch and other hidden data issues
A checklist for validating experiment results before you act
Attend live and you’re in the drawing for one of three free seats in Ronny’s course, Accelerating Innovation with A/B Testing.
See you there,
-Ashley
