I have an excel sheet laid out like so: +–id—+–val–+–timestamp–+ | 01 | 1.2

I have an excel sheet laid out like so:

+--id---+--val--+--timestamp--+
|  01   |  1.2  | 1340769912  |
|-------|-------|-------------|
|  02   |  1.6  | 1340769928  |
+-------+-------+-------------+

I’d like to get the average of values within a range of 60 seconds, or a variance of 60 in the timestamp column. I’ve tried a bunch of stuff in terms of Excel formulae, etc. but I can’t get it to work correctly. Is VBA the way to go?

EDIT: There’s a lot of data and a lot of minutes, I need this formula to work if I copy it down a column.

    If you have excel 2007 or later
    =AVERAGEIFS($B$1:$B$2,$C$1:$C$2,"<"&C1+60,$C$1:$C$2,">"&C1-60)

    for any version of excel:
    =AVERAGE(IF(AND($C$1:$C$2<C1+60,$C$1:$C$2>C1-60),$B$1:$B$2)) entered as an array formula using CTRL+SHIFT+ENTER to enter the formula, rather than just ENTER
