I am trying to get this formula to average the values in row I for all
individuals seen during the year 2008. The formula also acknowledges that it
should ignore any cell in row I, if it is blank. For some reason I cant seem
to get the formula to work, and I keep getting a #VALUE! error. Any
suggestions?

Thanks,

Dan

Below is the formula I originally wrote:
=SUMPRODUCT((--(YEAR('Raw Data'!$C$2:$C$3498)=2008)),('Raw
Data'!$I$2:$I5000)<0,AVERAGE('Raw Data'!$I$2: $I5000),"")

=SUMPRODUCT((--(YEAR('Raw Data'!$C$2:$C$3498)=2008)),('Raw
Data'!$I$2:$I5000)<0,AVERAGE('Raw Data'!$I$2: $I5000),"")

The ranges have to be the same size.

Try this array formula** :

=AVERAGE(IF(YEAR('Raw Data'!C2:C5000)=2008,'Raw Data'!I2: I5000))

** array formulas need to be entered using the key combination of
CTRL,SHIFT,ENTER (not just ENTER). Hold down both the CTRL key and the SHIFT
key then hit ENTER.

When I entered your formula as an array, the result in the cell merely said
"True". What I am attempting to do, is have the formula average all numerical
values in Column I, for those individuals who were admitted in 2008 ONLY. If
an individual was admitted in 2009, than the values posted in Column I (for
those individuals) should not be averaged in. I plan to average the Column I
values for 2009 admissions separately from 2008.

The other part of the formula just advises to leave the outcome blank, if no
values are posted in Column I, and no dates posted in Column C (the
spreadsheet is currently blank, as I haven't begun to enter data yet).

Again, thanks very much Biff!

02/02/2008 2
01/04/2009 3
04/05/2008 4

In some cell like D1 enter =AVERAGE(IF(YEAR(A1:A5)=2009,B1:B5)) and, since

Excel will place the formula within braces and give the correct result (here

So I have it working, however, the only other thing I need to account for (to
avoid DIV/0 and #Value! errors) is for the formula to ignore doing its
calculations when the admission dates in Column C are either blank, or
outside of the correct year paramaters of the formula (e.g. in your example
Bernard, 2009). Thus, any outcome number in Column I would be ignored, if
admission dates were from 2008, 2006, etc.

As a test on a blank spredsheet, I entered two dates in 2007 (Column C), and
two outcome numbers in Column H, and I received the DIV/0 error. If however I
add a 2009 date, the formula works. As opposed to the DIV/) error, I would
like the outcome to just leave the cell "blank", until the correct dates
(e.g. 2009) are included on the spreadsheet.

Here is what I added in an attempt to account for the above, but it would
not seem to work:

=AVERAGE(IF(YEAR('Raw Data'!C2:C50000)=2009,'Raw Data'!I2:I5000,AND('Raw

I'm using Excel 2007 (which I just began using yesterday after years of
2003). That additional piece of formula you added in Biff (IFERROR) did the
trick......THANK YOU SO MUCH. Now it works just perfectly. Sorry for any lack
of clarity on my part which resulted in so much back and forth. But I very
much appreciate the time you and Bernard took. The Excel Discussion Group has
saved my life on more than one occassion......

Thanks for the assistance. The formula resolution you offered
however
only
evaluates the formula, and returns a true statement. It did not
average
the
values I input inot Row I however. Did I miss something?

The ranges have to be the same size.

Try this array formula** :

=AVERAGE(IF(YEAR('Raw Data'!C2:C5000)=2008,'Raw Data'!I2: I5000))

I am trying to get this formula to average the values in row I for

individuals seen during the year 2008. The formula also

I
can't

Any

Below is the formula I originally wrote:
=SUMPRODUCT((--(YEAR('Raw Data'!$C$2:$C$3498)=2008)),('Raw
Data'!$I$2:$I5000)<0,AVERAGE('Raw Data'!$I$2: $I5000),"")

You're welcome. Thanks for the feedback!

I'm using Excel 2007 (which I just began using yesterday after years of
2003). That additional piece of formula you added in Biff (IFERROR) did
the
trick......THANK YOU SO MUCH. Now it works just perfectly. Sorry for any
lack
of clarity on my part which resulted in so much back and forth. But I very
much appreciate the time you and Bernard took. The Excel Discussion Group
has
saved my life on more than one occassion......

Best,

Dan

What version of Excel are you using?

If you're using Excel 2007. Still array entered:

=IFERROR(AVERAGE(IF(YEAR('Raw Data'!C2:C5000)=2009,'Raw
Data'!I2:I5000)),"")

For other versions of Excel. Still array entered:

=IF(SUM(--(YEAR('Raw Data'!C2:C5000)=2009)),AVERAGE(IF(YEAR('Raw
Data'!C2:C5000)=2009,'Raw Data'!I2:I5000)),"")

So I have it working, however, the only other thing I need to account
for
(to
avoid DIV/0 and #Value! errors) is for the formula to ignore doing its
calculations when the admission dates in Column C are either blank, or
outside of the correct year paramaters of the formula (e.g. in your
example
Bernard, 2009). Thus, any outcome number in Column I would be ignored,
if
admission dates were from 2008, 2006, etc.

As a test on a blank spredsheet, I entered two dates in 2007 (Column
C),
and
two outcome numbers in Column H, and I received the DIV/0 error. If
however I
add a 2009 date, the formula works. As opposed to the DIV/) error, I
would
like the outcome to just leave the cell "blank", until the correct
dates
(e.g. 2009) are included on the spreadsheet.

Here is what I added in an attempt to account for the above, but it
would
not seem to work:

=AVERAGE(IF(YEAR('Raw Data'!C2:C50000)=2009,'Raw
Data'!I2:I5000,AND('Raw
Data'!C2:C5000<"",AND('Raw Data'!I2:I5000<""))))

Biff's formula has to work
Let's try an experiment on a new sheet
In A1:B5 enter data like this
01/01/2009 1
02/02/2008 2
01/04/2009 3
04/05/2008 4
03/05/2009 5

In some cell like D1 enter =AVERAGE(IF(YEAR(A1:A5)=2009,B1:B5)) and,
since
it is an array formula, commit it with CTRL+SHIFT+ENTER not just
ENTER.
Excel will place the formula within braces and give the correct result
(here
3)

Can you get this to work? Now try on you actual worksheet
best wsihes

When I entered your formula as an array, the result in the cell
merely
said
"True". What I am attempting to do, is have the formula average all
numerical
values in Column I, for those individuals who were admitted in 2008
ONLY.
If
an individual was admitted in 2009, than the values posted in Column
I
(for
those individuals) should not be averaged in. I plan to average the
Column
I
values for 2009 admissions separately from 2008.

The other part of the formula just advises to leave the outcome
blank,
if
no
values are posted in Column I, and no dates posted in Column C (the
spreadsheet is currently blank, as I haven't begun to enter data
yet).

Again, thanks very much Biff!

I have no idea what you mean by that? Do you mean the formula
returned
the
logical value TRUE? I don't see how that's possible.

Did you enter the formula as an array?
