Help with averaging problem

[avigran]

We are trying to write a write a macro that will take the average of every four numbers like A1-A4 then A5-A8 is there a function we can utilize to help us analize this mountain of data we have that we could easily apply down the column?

You could put this in B4 (or any column, row 4) and drag down

=IF(MOD(ROW($A4),4)=0,AVERAGE($A1:$A4),"")


Or you could put this macro into the worksheet's module. It puts answers in column C

Sub AvEvery4Rows()

    Dim rng As Range    'range to work with
    Dim cel As Range    'individual cells within that range
    Dim Tally As Double 'total of the 4 rows being averaged
    Dim i As Integer    'incrementer, will be 0 to 1 less than number of rows
    
    Set rng = Range("A1:A" & Cells(Rows.Count, "A").End(xlUp).Row)
    
    For Each cel In rng
        If cel.Row Mod 4 = 0 Then
            For i = 0 To 3
                Tally = Tally + cel.Offset(-i, 0).Value
            Next i
            
            cel.Offset(0, 2).Value = Tally / 4
            
            i = 0
            Tally = 0

        End If
    Next cel
        
End Sub
