Help with Average Formula
Assuming your last row is 702 (assuming headers in row 1) with dates in Col A
and Value to average in Col B, enter this in C720 =Average(C338:C702) You can copy this formula UP till row 366 or till you get a #REF error (when you run out of 365 cells to average) "Please help" wrote: I have two years data in one excel spread sheet, I need to pull rollover average for 365 days (from today until 1 year earlier exp 27-Apr-09 through 26-Apr-2008) Can anyone help me please? |

Help with Average Formula
Could do something like:
=AVERAGE(OFFSET($A$1,COUNTA(A:A)-1,0,-365,1)) Note that I'm assuming you already have at least 365 points of data, or this formula will return an error. -- Best Regards, Luke M *Remember to click "yes" if this post helped you!* "Please help" wrote: Well I need the roll over daily 365 days average (as I add data on tomorrows report it should automaticly skip date tu current 365) "Sheeloo" wrote: Assuming your last row is 702 (assuming headers in row 1) with dates in Col A and Value to average in Col B, enter this in C720 =Average(C338:C702) You can copy this formula UP till row 366 or till you get a #REF error (when you run out of 365 cells to average) "Please help" wrote: I have two years data in one excel spread sheet, I need to pull rollover average for 365 days (from today until 1 year earlier exp 27-Apr-09 through 26-Apr-2008) Can anyone help me please? |

Help with Average Formula
thanks a lot but I found the right formula is =(SUMIF(A2:A900,"" &
H3-365,B2:B900)/365) "Luke M" wrote: Could do something like: =AVERAGE(OFFSET($A$1,COUNTA(A:A)-1,0,-365,1)) Note that I'm assuming you already have at least 365 points of data, or this formula will return an error. -- Best Regards, Luke M *Remember to click "yes" if this post helped you!* "Please help" wrote: Well I need the roll over daily 365 days average (as I add data on tomorrows report it should automaticly skip date tu current 365) "Sheeloo" wrote: Assuming your last row is 702 (assuming headers in row 1) with dates in Col A and Value to average in Col B, enter this in C720 =Average(C338:C702) You can copy this formula UP till row 366 or till you get a #REF error (when you run out of 365 cells to average) "Please help" wrote: I have two years data in one excel spread sheet, I need to pull rollover average for 365 days (from today until 1 year earlier exp 27-Apr-09 through 26-Apr-2008) Can anyone help me please? |
