How to write this function?
Say I have the following
A B 1 2 10 2 4 5 3 2 20 4 2 30 5 4 11 How can I write a func. so if the cell values are equal, for A col, it will add the values in corresponding B col, then average the value out? avg = SUM / #occur So in may example, A1,A3 and A5 are all 2's so... avg = 60 / 3 = 20 Again, A2 and A5 are both 4's so... avg = 16 / 2 = 8 Thanks! -- - Zilla (Remove XSPAM) |

One way ..
In C1: =SUMIF(A:A,A1,B:B)/COUNTIF(A:A,A1) Copy down -- Max Singapore http://savefile.com/projects/236895 xdemechanik --- "Zilla" wrote in message ...

Ok thanks, I'll try this way...

Thanks but this will be tedious since you hard-coded "2",
which is just an example value. So if I change "2" to "19", I'd have to change it in ALL the formulas...

Change the 2 to a cell address

You could point Topper's array suggestion to the source cells in col A
Eg in C1, array-entered (press CTRL+SHIFT+ENTER): =AVERAGE(IF($A$1:$A$100=A1,$B$1:$B$100)) Copy down (Adapt the ranges to suit before you copy down) -- Max Singapore http://savefile.com/projects/236895 xdemechanik --- "Zilla" wrote in message ...
