Perhaps something like:

=AVERAGE(LARGE(A1:A10,ROW(1:4)))

entered as an array formula with <Ctrl> <Shift> <Enter>. This will give you
the average of the 4 largest numbers in the range A1:A10.
 
Hi!

A non array entered version:

=AVERAGE(LARGE(A1:A100,{1,2,3,4}))

Of course, if you wanted the largest 50 you wouldn't want to use the above
method!

Another method:

=SUMIF(A1:A100,">="&LARGE(A1:A100,4))/4

Biff
