Average from first non-blank cell
 

I am trying to get a 12 cell average within a row, starting with the first
non-blank entry, working from left to right. All entries are numeric.
The following (inelegant) formula works, but is limited by the number of
conditions allowed in Excel.
=IF(H17<"",AVERAGE(H17:S17),IF(I17<"",AVERAGE(I1 7:T17),IF(J17<"",AVERAGE(J17:U17),IF(K17<"",AVER AGE(K17:V17),IF(L17<"",AVERAGE(L17:W17),IF(M17<" ",AVERAGE(M17:X17),IF(N17<"",AVERAGE(N17:Y17),AVE RAGE(O17:Z17))))))))
Can anybody assist with a more elegant solution that will give the correct
average even if the last entry is more than 7 blanks away?
Thanks

This formula must be **array-entered**:

=AVERAGE(OFFSET(A1,0,MATCH(TRUE,ISNUMBER(1:1),0)-1,1,12))
----------------------------------------

To **array-enter** a formula, after entering
the formula into the cell or formula bar, hold down
<ctrl<shift while hitting <enter. If you did this
correctly, Excel will place braces {...} around the formula.

If your first "non-blank" might not be in A1, in other words, if you might have
labels in Column A that are numeric, you might need to modify the range
references a bit. If those values are not numeric, then you will only need to
modify the row numbers.

Hi Chris
Thanks for the reply
Unfortunately, I am not familliar with macros. Tried copy paste into the
macro function but got runtime error 13.

Code:

Sub Calc_Average()
    Dim row As Integer, col As Integer
    row = 1
    col = 1
   
    Dim sum As Double
    sum = 0
   
    For col = 1 To 12
        If Sheet1.Cells(row, col).Value < "" Then
            sum = sum + CDbl(Sheet1.Cells(row, col).Value)
        End If
    Next
   
    Dim avg As Double
    avg = sum / col
   
    MsgBox "Average is = " & avg
End Sub

Tried your formula but it returns incorrect averages
Possibly look at the workbook I have sent you in case I have not entered the
ranges correctly
Thanks

Average of 12 cells, starting from first non-blank cell entry, working L to R

average in column A

Col A B C D E F G H I J K L M N O P Q R S T U
5.66 = B B B B B 4 1 0 -1 5 6 15 3 9 9 9 8 1 3 4
3.25 = 2 3 6 8 3 2 0 0 0 1 6 8 9 5 6 7 4 1 9 0

I hope this stays in a grid pattern.

Also, with regard to your results,

Row 1: Result is 5.6666666... or arithmetically rounded would be 5.67
Row 3: The average of the numbers : 6 5 4 3 3 6 is 4.5, not 2.25

Except for the discrepancy in results, especially with regard to Row 3, I would
have modified the formulas to:

=AVERAGE(OFFSET(A1,0,MATCH(TRUE,ISNUMBER(B1:Z1),0) ,1,12))

again --- **array-entered** as previously described.

Thats the question I need answered!
I calculated these manually.
Oops, you are correct, the result in the first row should be 5.666666
and the 3rd row s/be 4.5

When you wrote "Tried your formula but it returns incorrect averages", it would
have been helpful to know exactly what formula you tried! And what answers you
were obtaining and what answers you expected.
