Default how i calculate pearson correlation coefficient for excel grap

Correl is the better choice. In Excel 2003 and later Correl and Pearson are
identical. Prior to 2003, they are mathematically equivalent, but Peason is
numerically inferior.

In a cell in the worksheet, enter this formula

=CORREL({y range},{x range})


Shouldn't that be =PEARSON({y range},{x range})? I only have Excel 97,
but I'm surprised to see that PEARSON() and CORREL() do not have a
pointer to each other in the "See also" section of the help file.
