Hey people!
Is it possible to COUNTIFS Column C contains "Y" OR Column D contains "Y". Therefore COUNT should = 2
Is it possible to also AVERAGEIFS the Age if Column C OR Column D contains Y? Therefore average should = 37.5.
I have a spreadsheet that contains thousands of rows and hundreds of columns so I usually select my columns in formulas like this: $C:$C vs $C$2:$C$35
Countif:
Average

Thanks Bebo.
Perhaps I should have been more specific.
On the actual workbook I work from:
Age is located in column DG
FIRST is located in column V
SECOND is located in column JA
Therefore the formula would need to select each column individually $C$C AND $D$D rather than as a whole $C$2:$D$35 otherwise I would be selecting from $V to $JA..
Is there case of "Y" appear in the same row? (same patient with "Y" in both first and second)
Assum "Y" appear only one in both column, try:
Count:

Please try
Count
=SUMPRODUCT(--(MMULT(--(C2:D9="Y"),{1;1})>0))
Sum
=SUMPRODUCT(B2:B9,--(MMULT(--(C2:D9="Y"),{1;1})>0))
average
=Sum/Count
or Faster with Helper column
C2 =C2&D2
then
=COUNTIFS(E2:E9,"Y*")
and
=AVERAGEIFS(B2:B9,E2:E9,"Y*")
c2:d9 requires contiguous columns but I think the solution can be adjusted
Assuming
Column C and D are, in practice, not contiguous so solution uses them separately
We want to avoid row references in formula because there are thousands of rows
We want to treat correctly the cases where there are 2 Y's and where there are no Y's.
I added Patient 3 and 4 in the attachment to cover these two cases.
Does this work?
This requires a helper column, which I put in Column E.
Also needs to put a formula in each cell but we avoid row references
In each cell of Helper Column put =OR([at]C:C="Y",[at]D:D="Y")
The [at] stands for the "at" sign - it's in the attachment
Then average is written simply as
=SUMIF(E:E,TRUE,B:B)/COUNTIF(E:E,TRUE)
How does this get marked as solved? There are several answers which seem to work one way or the other.
It's not your thread, so not your call.

Thank you, that helps.
Supplementary question - How long do we have to post solutions for threads not yet marked solved? If this thread were open (not marked solved) for like 6 months, is it still OK? I'd like to work on another solution to this thread. Thanks in advance.

You can post a proposed solution to ANY thread, whether marked as solved or not. However, if a thread is marked as solved, the OP is less likely to see and respond to your additional help.
