If two variables are strongly correlated, does it necessarily always follow that there is a direct cause-and-effect relationship between the two variables? Can you think of two variables which are often associated with each other and are highly correlated, but there is no direct cause-and-effect relationship between them? For example, do you think it is a correct conclusion that watching soap operas gives girls eating disorders like anorexia if a study showed that "girls who watch soap operas are more likely to have eating disorders."
