• Label change from Uplift to MDE
• Description replaces "Uplift is the improvement (in %) you would like to achieve relative to the base conversion." with "Minimum Detectable Effect is the improvement (in %) you would like to detect relative to the base conversion."
     

Context

Feedback from Sandra:

• Our UI assumes an uplift, while MDE measures the relative change. If a variation performs worse than the original, there would be no uplift
• In addition, I believe that the description is not accurate. This metric does not relate to the improvement a user would like to achieve. Using the word “achieve” implies wishful thinking. Instead, it relates to the relative change in conversion rate a user would like to be able to detect. It is known as “Minimum Detectable Effect”

This is how Optimizely and AB Testy describe the Minimum Detectable Effect:

AB Tasty

See that they call it “Minimum Detectable Effect” and use the word “detect” in their explanation.
