Default How to average every 48 rows of data for 20,000 rows?

Forgot to mention that you should FILL DOWN the formula in columns G &
H before pasting in values.

Let's say your data is in A1:F20000. Click in cell G1 and type this
formula

=IF(MOD(ROW(),48)=0,"YES","NO")

Copy column G and paste values. Now column G has "YES" every 48th
row. In column H put

=IF(G1="YES",AVERAGE(A1:G1),"")

Again, copy and paste values if you want the hard-coded data to stick.

HTH,

Hi. I have a huge spreadsheet (~20,000 rows). I need to average every 48 rows
into one value. Is there a quick and easy way to do this without scrolling
through all 20,000 rows and copy-pasting the "average" function every 48th
row?
