Using Average with Subtotal function with criteria

[Rianne]

Hi, please help.
I have this group of filtered data which I need to get the average excluding NA and negative numbers.

My initial formula is =AVERAGE(IF(SUBTOTAL(9,OFFSET(FG$11:FG$500,ROW(FG$11:FG$500)-MIN(ROW(FG$11:FG$500)),,1)),--(FG$11:FG$500<>"NA"),--(FG$11:FG$500>0))) but unfortunately, not working.

Sample data:
24
12
-42895
NA
NA

Thank you!!

Will you please attach a sample Excel workbook? We are not able to work with or manipulate a picture of one.

1. Make sure that your sample data are REPRESENTATIVE of your real data. The use of unrepresentative data is very frustrating and can lead to long delays in reaching a solution.

2. Make sure that your desired solution is also shown (mock up the results manually).

3. Make sure that all confidential data is removed or replaced with dummy data first (e.g. names, addresses, E-mails, etc.).

4. Try to avoid using merged cells as they cause lots of problems.

Unfortunately the attachment icon doesn't work at the moment, so to attach an Excel file you have to do the following: just before posting, scroll down to Go Advanced and then scroll down to Manage Attachments. Now follow the instructions at the top of that screen.

Please pay particular attention to point 2 (above): without an idea of your intended outcomes, it is often very difficult to offer appropriate advice.

Hi, attached file for reference. Thank you.

That's no use, sorry - you have just copied and pasted values, so I am unable to look at and troubleshoot your formulae, as they are not there.

Hi Rianne,

The AVERAGE function doesn't need to take into account NA as it is naturally ignored by the formula. This simplifies things.

Try this formula - it worked on my version.
Array formula, enter the formula and hit CTRL SHIFT ENTER.
