How quick do you need it to be?
3K isn't much at all to most modern machines.
How do you know this is the problem area - I smell premature optimisation.
How often do you need to calculate the average - once?
How often does the data change?
If the data is pretty uniform, then getting the average of say the first 30 or first 300 (or pick a number) will give you an approximate answer.
But if the data has no useful properties you can make use of, then visiting all 3000 entries is unavoidable.
