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."

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).
according to microsoft, calculation differences (one pass vs. two) may impact the results from these two functions in versions prior to Excel 2003. in said versions, CORREL() is the more accurate.
