Question

find the median for tree 14, 92, 62, 53, 42, 32, 22, 31, 83, 55

Answer 1

14,22,31,32,42,53,55,62,83,92
n=10(even)
median=1/2(n/2 observation(n/2+1)observation)
           =1/2(5th observation+6th observation)
          =42+53/2
         =95/2
        =47.5
Hence, median is 47.5

Answer 2

by using formula (n+1/2)
we get 
(53+1/2)
=27 and othen median is 
(42+1/2)
=21.5


hope it helps!!!
