excluding valuse from an average
I am setting up a tracking spread sheet and I would like to be able to
average the weekly values and then average this for a monthly and a cumulative monthly average. The problem that I am having is there are certain weeks that there won't be any values. Is there a way to exclude these reading ( I am calling them "0" in this spread sheet ) and still be able to use the average function? Thanks in advance for any and all help in this matter |

If you leave them blank rathr than zero, AVERAGE() will ignore them.

Enter this an array formula Ctrl+Shift+Enter
=AVERAGE(IF(A1:A100<0,A1:A100)) or enter as normal: =SUM(A1:A100)/(COUNTIF(A1:A100,"0")+COUNTIF(A1:A100,"<0")) HTH "toot033" wrote: I am setting up a tracking spread sheet and I would like to be able to average the weekly values and then average this for a monthly and a cumulative monthly average.
