What is, and should I use Weighted Average?

Hi,
I calculate Sickness and Absence (S&A) data for my company, by department.
Each department can have between 5 - 100 people in it. I currently do a S&A
% of the department and then as company as a whole.
Because in one team we could have 5/10 people off = 50% S&A rate, yet in
another department 5/100 = 5%.
Is there a better way of calculating the % S&A for each department that will
give more meaningful data?
Thanks in advance,
AW
If you are trying to get to a company average others have steered you
well. But you are asking about meaningful data for departments, and I
think you are already there.
If it is normal to have an S&A rate of 9% company wide, a department
with a rate of 50% is clearly above normal, even within a reasonable
margin of error, and despite that department having a staff of 10.
