I am using an Excel spreadsheet with 2 numbers in every cell separated
my a
comma and a space (45, 55) and want to calculate the average for only
the
left numbers across a variety of cells [(45,55) (55,55) (65,85)].
Here the
averages I am looking for would be 55 for the left set of numbers and
65 for
the right set. I was wondering if there is any way to do this
automatically
in Excel instead of going through and doing them all manually. Any
help you
can provide would be most appreciated.

These are (x, y) pairs? Do they also include the parentheses? Here are
*array* formulas that can deal with parentheses whether they're
included or not.

x values in Rng:
=AVERAGE(--SUBSTITUTE(LEFT(Rng,FIND(",",Rng)-1),"(",""))

y values in Rng:
=AVERAGE(--SUBSTITUTE(MID(Rng,FIND(",",Rng)+1,256),")",""))
