Getting averages from a column

T

tommy

Hi, I would like to work out the average from a column of numbers but where
no data is available, it reads #N/A or #REF! So I can not use the automatic
system found in auto sum, is there any way around this. Also I think any
average would be influenced by any zeros in the column, Can any one help.
Thanks in advance, Tommy.

assuming your data is in a1:a8 and you want to exclude 0 values, try

=SUM(IF(ISNUMBER(A1:A8),A1:A8))/COUNTIF(A1:A8,">0")

entered using Cntrl+Shift+Enter

Does that mean you want to exclude 0?

This will exclude 0 and any errors. Array entered** :

=AVERAGE(IF(ISNUMBER(A1:A10),IF(A1:A10<>0,A1:A10)))

** array formulas need to be entered using the key combination of
CTRL,SHIFT,ENTER (not just ENTER)

You can use SUMIF and normally enter (assuming no -ve values with the
COUNTIF):

=SUMIF(A1:A8,"<1E100")/COUNTIF(A1:A8,">0")

Good catch on the negative values. Maybe change the countif to count.

=SUMIF(A1:A8,"<1E100")/COUNT(1/A1:A8)
