This table shows the median satisfaction scores for each service.  The scores can range from 1-5 with 5 being
the best (Excellent).  Overall the Air Force rated satisfaction highest with a median score of 4.81.  The Army
was next in beneficiary satisfaction (4.66) and the Navy was lowest (4.51).  The combined median was 4.61
which shows that beneficiaries of DoD healthcare are generally very satisfied with their ophthalmological care.
 

(See the graph below for a better understanding of the overall satisfaction scores for the three services.)

The most important figure in this table is the F of 11.078, which is significant at p < .001.  This means that
there is a significant difference in the level of satisfaction between Army, Air Force, and Navy beneficiaries
who receive care at DoD ophthalmology clinics in Region 6.
