Answer 2

The median is 15.

Step-by-step explanation:

Given : Data of marks and number of student.

To find : The median of the data?

Solution :

First we find the cumulative frequency,

Marks (x)                  Number of students(f)        CF

5                                    1                                        1

10                                  6                                        7

15                                  10                                      17

20                                  8                                       25

25                                  4                                       29

As N= 29 which is odd.

The median is given by,

$M= (\dfrac{n+1}{2}) th \text { term }$

$M= (\dfrac{29+1}{2}) th \text { term }$

$M= 15 th \text { term }$

The observation 15th  lies corresponding the CF 17.

and CF corresponding to the value of X (Marks ) is 15.

Therefore, the median is 15.
