Answer 2

Given : A group of data

To Find : Median & to draw less

than ogive

Solution:

Age of student (CI ) 5-7, 7-9, 9-11,

11-13, 13-15, 15-17.

no of students (F) 20, 18, 22, 25, 20, 15​

Less than CF : 7 , 9 , 11 , 13 , 15 , 17

Cumulative 20, 38, 60,85 , 105 , frequency , 120

Median is given by the x-coordinate of the point corresponding to n/2 as the y coordinate in ‘less than’ ogive.

• In an ogive given data is plotted on X axis.

• Cumulative frequency is plotted on Y axis.

• So, media of the data is
