1. (a) Everyone knows correlation is not causation." What is the difference? Present it symbolically, as captured in the potential out-comes model, and explain the meaning of these symbols in plain English.

(c) A student who took Stanford's version of PS3 is overheard at a party confidently declaring, "Randomized experiments are necessary for correlation to tell us causal effects such as ATT." How would you explain to this student the inadequacy of Stanford's training on this topic?
