1) An Example:
Does your #shoesize have an effect on your #income? If you look at the c#orrelation between shoe size and income, you will indeed find out: People with bigger feet have on average a higher salary!
But does that really mean that shoe size has an effect on income? No, because: Gender has an effect on both shoe size and income - so it's a #confounding factor in this context!
