Excel average problem

Excel average problem

Excel average problem

(OP)
When averaging a row of numbers.  I am trying to average the last 10 entries.  The problem is the row may have blank cells.
Example:
I am using row 3 and columns A-P.
Column entries are as follows;
A=10
B=20
C=(BLANK)
D=40
E=(BLANK
F=(BLANK)
G=70
H=(BLANK)
I=90
J=100
K=10
L=20
M=30
N=40
0=(BLANK)
P=50

this is the formula I am using
:=AVERAGE(OFFSET(INDEX(3:3,,COUNT(A3:T3)),0,-9,1,10))
the result is:55

I Check the answer with =AVERAGE(B3:P3)
this is my desired result:47

Any help is greatly appreciated

Thank you for your time!!

RE: Excel average problem

why not just use sum(b3:p3)/count(b3:p3)?

RE: Excel average problem

Hello,

May have found a long winded solution

in P4 enter this formula

=IF(P3<>"",1,"")

in O4 enter this formula

=IF(AND(SUM($P$4:P4)<10,O3<>""),1,"")

and copy this to A3

in a cell enter this formula

=SUMIF(A4:P4,"=1",A3:P3)/COUNTIF(A4:P4,"=1")

the answer given is 47.

Long winded I know, but it does work, is this a feasable option?

Alternatively if the number of values can change i.e. go beyind column P

enter this formula in A3

=IF(AND(SUM(Q4:$IV$4)<10,P3<>""),1,"")

and copy as far as required.
