Answer:
Given : The height (in cm) of students in a group
To Find : Median Height
Solution:
Arranging data in ascending order
Height f cf
152 18 18
153 10 28
154 21 49
156 23 72
158 12 84
159 14 98
98/2 = 49
98 is even
Hence Median = mean of 49th and 50 th term
49th term = 154 cm
50th term = 156 cm
Median = ( 154 + 156)/2 = 155 cm
the median height (in cm) of the students is 155 cm
