avg ?

what's wrong with this statement?

=AVERAGE(if A1:A65000="DFW",F1:F65000)

i want my spreadsheet to give me the average of the percentages listed in
column F where column A = dfw ...
thanks

Try,
=SUMPRODUCT(--(A1:A65000="DFW"),--(F1:F65000))/COUNTIF(A1:A65000,"DFW")
Regards,
Alan.

hi Tammy,
try it as array formula..
=AVERAGE(if(A1:A65000="DFW",F1:F65000))
press CTRL-SHFT-ENTER not just enter.

thanks guys - i need to add one more twist. I do not want it to include in
the average where there is a value of 0%. can you please tell me how to add
that?

hi tammy,

u have new condition but u can try this also Average + IF functions - array
formula

=AVERAGE(if(((A1:A65000="DFW")*(F1:F65000>0%)),F1:F65000))
or u can try also sumproduct + countif functions

regards

Another option is to insert a column next to F which we will call G (which
you can hide so it does not show on the table) Then create an if statement
for the cells on this new column and now drag & fill the cells in this new
column with the new formula
=IF(A1="DWF",IF(F1>0,F1,""),"")
which will only return the values for DWF that are greater than zero and
leave all the other cells blank for that column. The "" leaves the cells
blank so they are not populated with zeros which allows you to average the
only the cells with a numeric value. You can now place the average function
=average(G1:G65000) in any open cell to pull an average of the new column G
you created which you can now hide if you want to clean up you sheet.

There are other ways to do this with multiple formulas. The above is simple
& works

thanks everyone. both of those worked.

Driller & CSI -

I another function too please. I'm sorry I ddin't mention before. I didn't
see it til now.

I need
if Column A contains DFW and F >0, then I need G to = Bob
if column A contains AUS and F > 0, then I need G to = Lynette
so on so on so on.

Thanks,
Tammy

It depends on how many "so ons" you require. I am fairly certain if
statements only go 7 ifs deep. You need to explain better what you are trying
to accomplish. How many names do you potentially have? 5, 10 , 20 ? Are they
for information only? Do you need to count them or do anything special with
the names?

Last of all if you are using the method I described column G is already
being populated by numbers the formula is pulling out of column A for your
average. This would create a conflict since the cell can't equal both "bob"
and bob's "total" from A.

CSI -
I will have approx 300 so on's.

ditzy me - i wrote my question wrong again. But I have to add thank you for
answering my original question and it solved part of the problem for me. But
I have to take it one step even further.

I need <b>THE AVERAGE IF</b>

average if Column A contains DFW and F >0, then I need G to = Bob
average if column A contains AUS and F > 0, then I need G to = Lynette
so on so on so on. And there will be approx 300 If's.

Hi again Tammy,
i was surprised by the 300 ifs you need to build, and you still like to go
forward with the Average IF...with CTRL-SHFT-ENT.
so from my first and 2nd reply, wherein you need to extend the conditions to
try this
=AVERAGE(if(((A1:A65000="DFW")*(F1:F65000>0%)*(G1:G65000="Bob")),F1:F65000))

and
=AVERAGE(if(((A1:A65000="AUS")*(F1:F65000>0%)*(G1:G65000="Lynette")),F1:F65000))
Click to expand...
you can see the pattern from the two sample formula...

and press CTRL-SHFT-ENTER not just enter.

regards

dRILLER - is there a better way? Should I create some type of macro?
Can I type all 300 If's in one cell?

driller

Hi again Tammy,
no way for 300 if's in one cell...
ifrom your original post, you are looking for the average of a single column
of data based on different filtering/search match...I cannot see until now
that you will need 300 types of match for a single column of data....
what kinda data-base you are doing...Have u tried the excel function like

DAVERAGE(database,field,criteria)

Database is the range of cells that makes up the list or database. A
database is a list of related data in which rows of related information are
records, and columns of data are fields. The first row of the list contains
labels for each column.

you may need it for the better in such huge data-base..

hi again Tammy,
it is quite odd that the formula will result to a #DIV/0! error
message...Better use auto-filter on the column where there are division
formulas. Maybe there are uncompleted data results #DIV/0! along these
column(s)...otherwise you can try and repost again your problem, surely many
will reply to your meaningful post...
regards and good luck
