AVERAGE function
Can anyone tell me whether there is a way to average a whole column of
numbers but ignoring blank cells or cells with errors in e.g. Column A 1 2 4 5 3 5 4 DIV0! DIV0! 3 4 blank 2 Many thanks John |

Blanks are already ignored.
=AVERAGE(IF(ISNUMBER(A1:A100),A1:a100)) which is an array formula, it should be committed with Ctrl-Shift-Enter, not just Enter. -- HTH Bob Phillips (replace somewhere in email address with gmail if mailing direct) "JRD" wrote in message ...

Hi
One way would be the following Array entered formula {=SUM(IF(ISNUMBER(A1:A13),A1:A13,0))/COUNT(A1:A13)} Use Ctrl+Shift+Enter to commit or Edit the formula Do not type the curly braces { } yourself, Excel will enter them for you if you use Ctrl+Shift+Enter -- Regards Roger Govier "JRD" wrote in message ...

AVERAGE function
Hi Bob
I tried that first of all, but had used ,0 as the False argument to the If statement {=AVERAGE(IF(ISNUMBER(A1:A13),A1:A13,0))} and got a result of 2.538462 whereas the correct result (with the data as posted) is 3.3 Omitting the ,0 (as you did) gives the correct result. I am curious to know why it is that you can omit the false argument. I have never thought of doing so before, but clearly it makes for a shorter formula than my SUM()/COUNT() solution as posted.? -- Regards Roger Govier "Bob Phillips" wrote in message ...

AVERAGE function
Hi Roger,
Been out for a walk on this glorious day, so it wasn't that I was taking time thinking of the reason. The reason is that if you put 0 there, that counts as another element and skews the average. If you put nothing, it generates a FALSE for all the mismatches (just as =IF(A1="xyz",1) would do), and the FALSE values do not get averaged, just as TEXT does not. In your formula, you could use FALSE instead of 0 and it would have worked. =SUM(IF(... would be fine with a 0 for the FALSE action, but not AVERAGE, not MIN, not STDEV, etc. -- HTH Bob Phillips (replace somewhere in email address with gmail if mailing direct) "Roger Govier" wrote in message ...

AVERAGE function
If I may - when the false argument is excluded, IF returns FALSE for false
conditions and AVERAGE ignores logical values.

Hi Bob
After posting, I went out for lunch ( and a nice drop of Old Speckled Hen). Whilst gently sipping, I had decided that my putting 0 for the false argument, was what was giving the problem as these would be values and whilst they would not raise the total, they would raise the divisor to 13 (from 10). I had meant to try on my return using "" (null) in place, but your post has confirmed. The next posting, also confirms to me that omitting the False part of the argument, defaults to False. As usual, I learn something new every day!!! -- Regards Roger Govier "Bob Phillips" wrote in message ...

Hi
Thanks for that. On reflection, I had come to the conclusion that, had I used Nulls ("") rather than 0's in my IF clause, it would probably have worked. I had not realised that omitting the False argument, automatically returns FALSE for False. Thank you for helping me learn something new today. -- Regards Roger Govier "JMB" wrote in message ...
