i want to do average of large set of data. For example 1,1,1,1,2,2,2,2,2,3,3,4,4,4,4,5,5,6,7,7,7,7,7,7

i need average of 1,1,1,1 and than 2,2,2,2,2 and than 33 and than 4444 and than 55 and than 6 and than 777777. is it possible ? can any one help me in this ?

=IF(MOD(ROW(),20)=1,AVERAGE(OFFSET(K1,,,20)),"") works but only same number of bin every time. here,  bin is variable ...looking answer from some expert...

Why not simply use a PivotTable?

Average of 1,1,1,1 = 1
Average of 2,2,2,2,2 = 2
Average of 3,3 = 3

i have acquired the data from experiment. The data is in excel form. I have attached the sheet with question. This contains about 2000 data points. Like this , i have 40 sheets. I was looking for some formula in excel which can solve this.

this formula
=IF(MOD(ROW(),20)=1,AVERAGE(OFFSET(K1,,,20)),"")
gives me average of 20 data sets and i have to pull the formula up to 2000 data points. However,in my case the interval is not fixed. It depends on repetition of number.

please see the attached file.

But your values in column F are not the same, they are rounded to 1 decimal place. Do you want the average based on the rounded value?

If so, in column H:

=ROUND(F1,1)

and in column I

=IF(H1=H2,"",AVERAGEIF($H$1:$H$2005,H1,$G$1:$G$2005))

Copy both down as far as required. The Average will show on the last entry for each value in F.
