What does "Dependent Variable" mean?

Definition of Dependent Variable in the context of A/B testing (online controlled experiments).

What is a Dependent Variable?

A dependent variable is any variable that could be influenced by the intervention we are testing. In an A/B test this would be any outcomes of interest such as conversion rate, average revenue per user, average order value and others. A dependent variable is usually modeled as a random variable (a parameter behaving as if produced by a stochastic process).

Contrast this to an independent variable such as a user's age, sex, location, and so on, which is fixed in time and therefore cannot be influenced by anything a conversion rate optimization expert attempts.
