Select cells excluding 0 and average them

[wallstudio]

I am trying to figure out a formula to average 5 cells in column B. Column A is date in ascending order. Cell C1 is the date reference to search values in column B. However, the date in C1 is the middle date of the 5 dates which should be average. That means if C1 is 2011/1/3, the date range to be included will be 2011/1/1 to 2011/1/5. One more criteria is that the range should be expanded if there are dates with 0 value. That means if value on 2011/1/4 is 0, the date range should be 2011/1/1 to 2011/1/6.

Thanks for help.

Thank you Ganjin. What I need is to exclude all the blank cells and expand the selection with a total count of 5. The example below shows that the range should be from 31/12/10 to 08/01/11 with a total of 5 values to average and get the result of 34.

31/12/10 10 3/1/2011
01/01/11
02/01/11 20
03/01/11 30
04/01/11
05/01/11
06/01/11 50
07/01/11
08/01/11 60

 

[Ganjin]

ah ic, didn't consider the top bit.
hmm, okay try this one:

=SUMPRODUCT(($B$1:$B$1000)*($A$1:$A$1000 > C1-3-COUNTIF(INDEX(A:B,MATCH(C1-1,A:A,0),2):OFFSET(INDEX(A:B,MATCH(C1,A:A,0),2),-2,0),""))*($A$1:$A$1000 < C1+3+COUNTIF(INDEX(A:B,MATCH(C1+1,A:A,0),2):OFFSET(INDEX(A:B,MATCH(C1,A:A,0),2),2,0),"")))/5

on retrospect, if you asking what I think you are asking,
then, I would be interested in seeing the solution as well, because if you had something like this:

urg ...
will keep working on it, but drawing a blank at the moment x_x ...

I'm sorry. If I apply the formula to my above example, it shows 22, which I think it only includes 4 values instead of 5 in total. The answer should be 34. And the date range is from 31/12/10 to 08/01/11. Thanks.

 

[wallstudio]

In your post #6, the date range should be from 26/12/10 to 08/01/10 with a total number of 5 days with values. Thanks for your help, Ganjin.

 

[Ganjin]

np, love a good challenge
this formula is large but it should achieve what you want ...

Assuming C1 has the Date, C2 Formula:
=(INDEX(B:B,LARGE(ROW(B1:OFFSET(B1,MATCH(C1,A:A,0)-2,0))*(B1:OFFSET(B1,MATCH(C1,A:A,0)-2,0) <> ""),1),1)
+INDEX(B:B,LARGE(ROW(B1:OFFSET(B1,MATCH(C1,A:A,0)-2,0))*(B1:OFFSET(B1,MATCH(C1,A:A,0)-2,0) <> ""),2),1)
+INDEX(B:B,MATCH(C1,A:A,0),0)
+INDEX(B:B,LARGE(ROW(OFFSET(B1,MATCH(C1,A:A,0),0):B1000)*(OFFSET(B1,MATCH(C1,A:A,0),0):B1000 <> ""),COUNTA(OFFSET(B1,MATCH(C1,A:A,0),0):B1000)),1)
+INDEX(B:B,LARGE(ROW(OFFSET(B1,MATCH(C1,A:A,0),0):B1000)*(OFFSET(B1,MATCH(C1,A:A,0),0):B1000 <> ""),COUNTA(OFFSET(B1,MATCH(C1,A:A,0),0):B1000)-1),1))/5
Ctrl+Shift+Enter
