    ignoring #N/A in column average, stdev, etc

    I am trying to determine the average, stdev, min, max of a column of data that contains #N/A (empty) cells. I'd just like to ignore all the #N/As in the column.

    How best to do this?

    Here's a sample
    0:00:03
    0:00:07
    #N/A
    #N/A
    0:1:09
    0:1:16

    I tried =AVERAGE(IF(ISNUMBER(P2:P65), P2:P65)), but I think that is not calculating anything if a single #N/A is found.

    Thanks!

    The formula you posted will work if you confirm as an Array - that is to say you commit the formula using CTRL + SHIFT + ENTER rather than using Enter as would normally be the case.
    Once the Array is set successfully then the formula will appear encased within { } [you can not type these in]

    You could use:

    Or if you're running XL2007 you can use AVERAGEIF
