Avg % above 0%
How can I get the average percentage of a collumn of percentages without it
including any 0%. e.g. A1=0% A2=100%, A3=70% if it averaged the 3 cells it would be 57% but if it only averaged A2:A3 it would be 85%. I may have several cells in the collumn which is showing 0% so how do I average just those above 0%. Can you use Avg if is there such a formula? Basically I have a collumn of attendance data which I am trying to get the avg of. sometimes it will be 0% because its a non expected attendance and sometimes it will be because they did not attend though they should have done. hope this make sence. So in essence sometimes I want to add the 0% in the avg and sometimes I don't how do I diferentiate between when I do and when I don't -- Wendy Fillingham |

Avg % above 0%
Hi,
Here's 2 ways, first an ARRAY formula =AVERAGE(IF(A1:A1000,A1:A100)) This is an array formula which must be entered by pressing CTRL+Shift+Enter 'and not just Enter. If you do it correctly then Excel will put curly brackets 'around the formula {}. You can't type these yourself. If you edit the formula 'you must enter it again with CTRL+Shift+Enter. or a non array solution =SUM(A1:A100)/(COUNTIF(A1:A100,"0")+COUNTIF(A1:A100,"0")) -- Mike When competing hypotheses are otherwise equal, adopt the hypothesis that introduces the fewest assumptions while still sufficiently answering the question.

Avg % above 0%
Wendy,
In the event you have Excel 2007 =AVERAGEIF(A1:A10,"0") best wishes -- Bernard Liengme Microsoft Excel MVP http://people.stfx.ca/bliengme "Wendy" wrote in message ...
