# Thread: step increase average (2003)

1. ## step increase average (2003)

I have a column of daily data for which I would like to get the total average value for each day.
For example, if the data are in column A:
B2 formula would be =average(A1:A2)
B3 formula would be =average(A1:A3)
B4 formula would be =average(A1:A4)
B5 formula would be =average(A1:A5)
etc.

as I am looking at 15 years of data, is there a relatively easy way to do this?
Thanks.

In B2, enter the formula =AVERAGE(A\$1:A2)
Either double click the fill handle (the little black square in the lower right corner of B2), or select B2, then shift+click on the last cell with data in column B, and press Ctrl+D to fill down.
The \$ in A\$1 causes the 1 to be absolute, i.e. it won't be adjusted as you fill down.

thanks. I thought I was over-thinking it, and I was.
