I am trying to set up a spreadsheet where the lenght of each call goes in a
column.
I need to the show average call lenght at the bottom of the chart.
As the figures are updated frequently I need a formula that will work out
the average of the data entered. When doing the =SUM(D3:D15)/COUNT(D3:D15),
it is counting the blank cells and giving a very false averge. I have tried
going into the excell advanced options and unticked the box SHOW A ZERO IN
CELLS THAT HAVE A ZERO VALUE.

I would have thought this would be quite easy to do. I am intermediatery at
ecel, or so I thought!

Help would be most greatfull
 
BTW,
=AVERAGE(D3:D15) will ignore blank cells when calculating, but not cells
containing 0 (zero). If your column contains blanks but not 0's, this would
be the more efficient function to use.

Why are you not just using

=AVERAGE(D3:D15)

Neither AVERAGE, SUM, nor COUNT will include blank cells, or even cells that
have spaces in them.

If it were that there were 0 values but zeroes are suppressed and you want
to not count zero, then use this array formula

=AVERAGE(IF(D3:D15<>0,D3:D15))
