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


You would use a weighted average for the company as a whole. With your example
above, the company would have a S&A rate of 9.09%, which is calculated as total
"off" / total people [(5 + 5) / (10 + 100)]. That would be different than if
you would "average the averages" [(50% + 5%) / 2 = 27.5%].
