a: correlation coefficient ~
b: recipe


"The same is true with the correlation coefficient (and statistics in general). The formula for a correlation coefficient is like a recipe. The information that goes into it (∑X, ∑Y, etc.) are the ingredients. If you put the wrong ingredients into the formula, you will get a number that may very well look like a correlation coefficient. The only problem is that it is a defective correlation coefficient. Therefore, it will not mean what it should mean."
