Question

find the median height 13. 4, 10.6, 12.7, 17.2, 14.3, 15, 16.5, 9.8,

Answer 1

Arrange all heights in numerical order:
9.8,10.6,12.7,13.4,14.3,15,16.5,17.2
median = average of ( 13.4,14.3)
             =  (13.4+14.3)/2
             = 27.7/2 = 13.85
therefore the median of heights is 13.85
