I am trying to reduce a large dataset of 266 individuals of 23 species into
one that just includes the means of each species. Species names are text
entries in column C. There are some missing data points, so I could not
simply use:
=SUMIF(Main!$C$2:$C$266,$C11,Main!FF$2:FF$266)/COUNTIF(Main!$C$2:$C$266,$C11)
because the countif is not counting the exact cells going into the sum.

So my current approach is to use DAVERAGE. I am specifying the
worksheet(Database?), column, and criteria. The criteria compares text in
the 2 columns

Daverage(Main!1:65536,FF$2:FF$266,Main!$C$2:$C$266 =$C11)
however, I am getting a #VALUE error.
any help, thanks

How about something like:

=SUMPRODUCT(--(Main!$C$2:$C$266=$C11),Main!$FF$2:$FF$266)/SUMPRODUCT(--(Main!$C$2:$C$266=$C11),--(Main!$FF$2:$FF$266<""))

That does seem to work locally, but I can't spread it across the spreadsheet
without getting a VALUE error. I then tried removing the dollars signs from
the moving cells FF, but have not quite got it yet.

Try this array formula

=AVERAGE(IF(Main!$C$2:$C$266=C11,Main!$FF$2:$FF$26 6))

Hi Bob,
your formula: =AVERAGE(IF(Main!$C$2:$C$266=C11,Main!$FF$2:$FF$26 6))

returns 0, when I am expecting a nonzero return.


Elkar's formula works, but only in that one cell.

Where are you moving the formula to? What data needs to change as the
formula is copied to different cells? If you provide this info, I could
probably suggest a fix for the formula.

Hi Elkar, I am copying the formula across both columns and rows of the
current worksheet. My goal of the current worksheet is to generate species
mean values from the "Main" worksheet. Hence column FF will need to change
to FG, FH, etc as it is copied, but row number should not change.
I am away from work right now, but I think I tried this and it gave me VALUE
error.

What about cell C11? Would that need to change to C12, C13 etc when copied
down? If not, try making that absolute $C$11.

Hi,

There is some problem in the criteria of your formula. The criteria has to
be a range of cells and not an equation such as what you have used
(Main!$C$2:$C$266=$C11). Also please ensure that the headers of the range
and criteria are the same.

Elkthar formula is very close, and does copy across cells now , however there
are some slight discrepancies in the mean values it returns. Also, for many
columns it returns VALUE error. I think the two arrays are not always the
same size, and thus it can't multiply those arrays.
=SUMPRODUCT(--(Main!$C$2:$C$266=$C8),Main!AZ$2:AZ$266)/SUMPRODUCT(--(Main!$C$2:$C$266=$C8),--(Main!AZ$2:AZ$266<""))

One of the problems I have is that for some of the cells in AZ(or other
moving data columns) return #VALUE, which means that the formula which calls
for those cells also returns #VALUE. Any global settings in Excell that let
one handle missing data efficiently? It is getting tedious to be constantly
entering formulas to make blanks. for example:
=IF(OR(ISBLANK(DL21),ISBLANK(AF21)),"",DL21/AF21)

You may be better changing your
=IF(OR(ISBLANK(DL21),ISBLANK(AF21)),"",DL21/AF21)
to
=IF(OR(DL21="",AF21=""),"",DL21/AF21)

ISBLANK will not be true for cells containing a formula that results in "".

Here is the current formula for a cell:

=SUMPRODUCT(--(Main!$C$2:$C$266=$C2),Main!I$2:I$266)/SUMPRODUCT(--(Main!$C$2:$C$266=$C2),--(Main!I$2:I$266<""))

The problem is that when it finds DIV/0 or #VALUE errors anywhere in the
column it is searching, it then returns a #VALUE error. I would like to make
it more robust and able to still give a numeric return despite errors in some
of the cells it is searching. In the numerator of the above formula, maybe
instead of the criteria just "" also have 'not ERROR' or something like that.
any ideas how to specify that?
thanks

Its really best to do your Error Handling at the source. Whichever formulas
are generating the #VALUE errors (or any error for that matter) should be
re-written to allow for this. Such as:

=IF(ISERROR(your forumla),"Error",your formula)

This will allow you to still be notified when an error occurs, but will also
allow Excel to continue to perform calculations on your results since they're
now simple text values rather than an usuable error.

But, if you really want bypass this advice, you might be able to get away
with something like:

=SUMPRODUCT(--(IF(ISERROR(Main!$C$2:$C$266),0,Main!$C$2:$C$266)= $C2),--(IF(ISERROR(Main!I$2:I$266),0,Main!I$2:I$266))/SUMPRODUCT(--(IF(ISERROR(Main!$C$2:$C$266),0,Main!$C$2:$C$266)= $C2),--(IF(ISERROR(Main!I$2:I$266),0,Main!I$2:I$266)<"") ))

This would be entered as an ARRAY formula, so press CTRL-SHIFT-ENTER instead
of just ENTER.
