I am looking to apply the conditional average
to alternate columns.

Hmmm...

That sounds like trouble!

This formula will average cell C26 across your 10 sheets excluding 0 and
negative values:

=SUMPRODUCT(SUMIF(INDIRECT("'am
peak_"&10*{1,2,3,4,5,6,7,8,10}&"'!C26"),"0"))/SUMPRODUCT(COUNTIF(INDIRECT("'am
peak_"&10*{1,2,3,4,5,6,7,8,9,10}&"'!C26"),"0"))

You can shorten the formula a little by using a defined name.

InsertNameDefine
Name: Sheets
Refers to: =10*{1,2,3,4,5,6,7,8,9,10}

Then:

=SUMPRODUCT(SUMIF(INDIRECT("'am
peak_"&Sheets&"'!C26"),"0"))/SUMPRODUCT(COUNTIF(INDIRECT("'am
peak_"&Sheets&"'!C26"),"0"))

Yes, that's right. I tried to work around with the solution previously
provided, for which i renamed the sheet as 'am peak_1', 'am peak_2' and so
on... as it seems to not recognize the increment of 10 (ie. 10, 20...).
And
it worked (with one particular cell location though)! But as the cell
location is a text in the above stated formula, I am not sure how I can
apply
that to a group of cells. As in my case, I am looking to apply the
conditional average to alternate columns.
In one of the other threads under the same topic, the suggestion was to
use
the IF statement and create another table, replacing <0 values by "" and
then
calculate average. Though the solution is pretty simple, I am hoping
there
would be a 'one formula' solution to this problem, as I need to extract
such
averages for 18 scenarios (ie. 18 different excel sheets)!

Thanks,

average ... the same cell across 10 sheets
sheets are labeled 'am peak_10' to 'am peak_100'
ignoring the value if it is <=0

If you have 10 sheets named "10" to "100" then I'm assuming the names
increment by 10?

'am peak_10'
'am peak_20'
'am peak_30'
'am peak_40'
etc
etc
'am peak_100'

What if I have to take the average of the values located in the same
cell
across 10 sheets (ignoring the value if it is <=0). For instance, the
sheets
are labeled 'am peak_10' to 'am peak_100' and the cell location is C26.
I
am not quite familiar with the 'indirect' function hence not able to
comprehend the above solution.
Any help would be appreciated. Thanks!

AWESOME Solution! I would never had thought to try that.

Thank You very much!

Conditional calculations across sheets isn't easy. Try this:

=SUMPRODUCT(SUMIF(INDIRECT("'7-"&ROW(INDIRECT("1:31"))&"'!N:N"),"0"))/SUMPRODUCT(COUNTIF(INDIRECT("'7-"&ROW(INDIRECT("1:31"))&"'!N:N"),"0"))

I have an AVERAGE IF formula that works fine on a single worksheet
for
July
1st...
=AVERAGEIF('7-1'!N:N,"0",'7-1'!N:N)

I need it to work across 31 worksheets, so it will accurately
calculate
the
averages for all values greater than zero, and for the entire
month.

Any ideas?
