Averaging seconds

[Guest]

I am trying to figure out how to average a set of seconds to be used in a
graphing. Here is the data I have.

I need to average the seconds for each ID #. I have used the custom format
to make sure it is all in the [h]mm:ss format and I keep getting the #DIV/0!
error. Any suggestions?

Try

=AVERAGE(IF(B2:B200=4223,C2:C200))

which is an array formula, it should be committed with Ctrl-Shift-Enter, not
just Enter.

I am still getting the #DIV/0! error... if I use =AVERAGEA(C2,G2) it gives me
0:00:00. All I want to know is if it took 21, 42, 35, and 51 seconds to do a
specific task what is the average? But also keeing it in the colon format...

Try

=AVERAGE(IF(B2:B200=4223,C2:C200))

which is an array formula, it should be committed with Ctrl-Shift-Enter, not

You asked how to get an average per id. I showed how for one particular id.
Format has nothing to do with it just use a time format.
