This information gives us average value references for the amount of time
currently spent by principals on teaching courses, administrative tasks, public
relations building, crisis management, and miscellaneous affairs (Table

Empirical Analysis
The definition of 2.2 can obtain teaching courses, administrative tasks, public
relations building, crisis management, and miscellaneous affairs. Interval is (2; 1),
(2.5; 1), (2; 0.5), (1.5; 0.5), and (2; 1) hours. This range is the sought fuzzy sample
median (Table
2
).
