Average Goal Calculation
 

I am trying to average 35 every week in my Sunday school.
Last week, I had 32, the week before that 36. I would like a formula to tell me how many I need on the next Sunday, to average 35 for the year. All of the weeks are in column c (C2:C53) I would like 1 cell at the bottom of column c to have the answer continually update itself when I insert Sunday's attendance. What do I do?

Average Goal Calculation
 

Heya Thomas

what you need is Goal Seek but you will have to do it weekly. in the table
below go to cell F2 (average formula) and in the DATA Menu What-if analysis
click Goal Seek. in the box that open - Set cell is you selected cell (F2)
To value put 35 By changing cell C4 Enter when calculation finished
cick OK. you will see in cell C4 that you need 37 more to make your average
35. just paste this value in cell D4 and when you know the actual attendence
just overwrite the 37 in cell C4 this way you also check your progress viz
required and actual.

A B C D E F
1 Attnd Attnd Req Avg
Avg Req
2 Week1 36 35 =AVERAGE($C$2:$C$53) =AVERAGE($C$2:$C$53)
3 Week2 32 34 =AVERAGE($C$2:$C$53)
4 Week3 37 =AVERAGE($C$2:$C$53)

another way (without going to GoalSeek):

in C1:

=(1+COUNTA(C2:C53))*(35-SUM(C2:C53)/COUNTA(C2:C53))+SUM(C2:C53)/COUNTA
(C2:C53)

Please Clarify
 

I have been trying to understand this principle but need you to clarify your instructions.

Example:

C1 2010 (Year) To Avg. 35 (Title)

C2 36 Formula (Need 34)
C3 32 Formula (Need 37)
C4 34 Formula (Need 38)


The formula needs to adjust calculating all the weeks prior to it to be able to avg. 35 for the year

Thank-you

Jarek didn't say
=3D(1+COUNTA(C2:C53))*(35-SUM(C2:C53)/COUNTA(C2:C53))+SUM(C2:C53)/COUNTA
(C2:C53)

He said
=(1+COUNTA(C2:C53))*(35-SUM(C2:C53)/COUNTA(C2:C53))+SUM(C2:C53)/COUNTA
(C2:C53)

I don't know where you got the 3D from. Perhaps it was introduced by
EggHeadCafe? You'd be better off accessing the newsgroup directly using a
news server and a newsreader.
