How do you test for causality?
Once you find a correlation, you can test for causation by running experiments that “control the other variables and measure the difference.” Two such experiments or analyses you can use to identify causation with your product are: Hypothesis testing. A/B/n experiments.
Can causation be proven?
In order to prove causation we need a randomised experiment. We need to make random any possible factor that could be associated, and thus cause or contribute to the effect. If we do have a randomised experiment, we can prove causation.
