What is the difference between these two statistical functions? The equations for both look exactly the same, except for Pearson is w/an "r" and CORREL is w/an "x,y."

How to total the visible cells?
From the first blank cell below a filtered data set, press Alt+=. Instead of SUM, you will get SUBTOTAL(9,)

Excel's Help lists the same underlying formula for both PEARSON and CORREL.

just looking at the variables I would say they are using a different coordinate system (radius and angle to identify a point as opposed to x and y coordinates).
