Rolling Average
I have a sheet that needs to calculate a 53 week rolling average. Column A has the week number; Column B has the data to be averaged. I'm familiar with the offset function when charting and wonder if this can be replicated for calculating an average to match my chart. -- SPenney ------------------------------------------------------------------------ SPenney's Profile: http://www.excelforum.com/member.php...fo&userid=1079 View this thread: http://www.excelforum.com/showthread...hreadid=510252 |

Rolling Average
Hi!
So, what do you want to do? Average the last 53 entries in column B? What if there aren't 53 entries? Biff "SPenney" wrote in message ...

Rolling Average
Assuming that Column B, starting at B2, contains your data, try...
=AVERAGE(OFFSET(B2,MATCH(9.99999999999999E+307,B2: B65536)-53,0,53)) Hope this helps! In article , SPenney wrote: I have a sheet that needs to calculate a 53 week rolling average.
