There's probably something I'm doing wrong which I'm not seeing. But the average being calculated seems completely off.
This is an extract of the data:
R S T
29 3,90 % 0,01 % 0,98 %
30 4,22 % 0,57 % 1,62 %
31 4,53 % 1,06 % 2,18 %
32 4,81 % 1,49 % 2,68 %
33 5,07 % 1,87 % 3,13 %
34 5,31 % 2,20 % 3,53 %
35 5,54 % 2,50 % 3,90 %
36 5,76 % 2,77 % 4,23 %
37 5,96 % 3,02 % 4,54 %
38 6,15 % 3,24 % 4,83 %
39 6,33 % 3,44 % 5,09 %
40 6,50 % 3,62 % 5,34 %
The formula for S40 is =AVERAGE(R29:R40)
The formula for T40 is =SUM(R29:R40)/12
Is AVERAGE not the right function? What should I be using?
