First, lets put the number in numeric orders
21 , 21.4 , 22 , 22.7 , 25.1 , 25.5 ,
Lets find now the median of our number, wich means the middle number
median = 25.5
Identify minimum and maximum:
minimum = 21 maximum= 38.2
lets find the number on the lower and upper halves
lower half = 21 , 21.4 , 22 , 22.7 , 25.1
upper half = 26.6 , 29.5 , 33.1 , 35.9 , 38.2
Now we need to find the median of wich halves
median lower half = 22
median upper half = 33.1
