Document Summary
Age old mantra of correlation does not imply causation . True, good to know, but not constructive. Let"s begin with a overly simplified, stylized example for motivation, and then iterate. This is commonly referred to as the potential outcomes framework. Most experimentation done in industry follows this framework closely, as it is extremely practical to use, interpret, and engineer. Suppose we have drug that we believe improves shoulder mobility (increases the angle of vertical lift) Further, imagine we live in a vacuum . That is, there are no other factors that could possible help my shoulder. We assumed we were in a vacuum , so the only thing that could have aided my shoulder mobility was the drug. Assumption is too strong for reality - other factors exist. Also, we cannot actually observe both states of nitin at the same time. That is, i cannot simultaneously both take the drug and not take the drug.
