calculating the mean

[Guest]

I apologize for this stupid question, but I'm trying to calculate the mean of
the following cells and format it into a percentage
E3 189
F3 93%
G3 198
H3 93%
I3 211
J3 92%
K3 196
L3 93%
M3 224
93332% -


Here's my formula:
=(B3*C3)+(D3*E3)+(F3*G3)+(H3*I3)+(J3*K3)+(L3*M3)/(C3+E3+G3+I3+K3+M3)

Please help!
Thanks

=AVERAGE(Range)

your formula looks more like you are trying to get some weighted average?


If you add some parenthesis

=(B3*C3)+(D3*E3)+(F3*G3)+(H3*I3)+(J3*K3)+(L3*M3)/(C3+E3+G3+I3+K3+M3)

if you change the setup a bit and you put all the percentage in one range
and the other values in another range with both ranges the same size you
could use

=SUMPRODUCT(C3:H3,C4:H4)/SUM(C4:H4)

percentage in C3:H3 and the other values in C4:H4

Not the best way to arrange the data. But to correct your formula, you
only need to insert some parentheses around the entire numerator, just
as you have them around the denominator, to wit:

=( (B3*C3)+(D3*E3)+(F3*G3)+(H3*I3)+(J3*K3)+(L3*M3) ) /
(C3+E3+G3+I3+K3+M3)
