how do you input the formulas in excel to calculate the geometric mean?

Hi there:

Try this:

=PRODUCT(A1:A10)^(1/COUNT(A1:A10))

how do you input the formulas in excel to calculate the geometric mean?

Look at HELP for the GEOMEAN worksheet function.

IF GEOMEAN() is overflowing, then so will KL's equivalent formula.

=EXP(AVERAGE(LN(data)))
or
=EXP(AVERAGE(IF(ISNUMBER(data),LN(data))))

is a more robust calculation. Both formulas must be array entered
(Ctrl-Shift-enter). The second formula permits empty and non-numeric
cells in the data range.
