I found these data concerning influenza vaccination coverage in Italy. I don't understand how the total is calculated. It is not a simple media.
For example, for the season 2016-2017 the data are as follows:
If I sum up the values of the first line (in red) and average it, I get:
0.5+0.6+0.7+0.8+0.8+1.6+6.4+48.2=59.6/8=7.45 that is different from 14.6.
If instead I sum up the values of the column (in blue) I get:
0.5+0.5+0.6+0.7+2+1.2+0.3+0.9+1.3+5.2+0.3+0.9+0.5+0.6+0.8+2.4+4+0.2+0.6+1.3+1.1=25.9/21=1.23 that is different from 1.5.
So, what kind of calculations were made to get the Total values?
Can someone help me?
