What is the real difference between between correlation and regression analysis? I see that correlation allows us to examine whether two variables exhibit some kind of association with each other. Does correlation mean means that one variable is dependent on another? Is this an example of correlation - Tips are dependent on the actual restaurant bill? Can you give other examples of correlation and regression?

Thanks.
