Is it correct to assume that if two variables are correlated, there must be a direct link or cause from one to the other?
What will be an ideal response?
Two variables or measures may be highly correlated but not directly related to each other. In particular, it is possible that some third, unobserved variable is the cause that influences the two variables that have been measured. For example, while coming from a broken home and committing crime are correlated, it may be that poverty is the cause of both crimes and broken homes.
