Answer 2

GIVEN:-

The marks of 15 students in an examination are 25,19,17,24,23,29,31,40,19,20,22,26,17,35,21

TO FIND:-

The median and mode.

UNDERSTANDING THE CONCEPT:-

First you have to arrange all the numbers in ascending order like 17,17,19,19,20,21,22,23,24,25,26,29,31,35,40.

Then we have given the total no. of students = 15

So by using,

$= > \dfrac { n + 1}{2}$

$= > \dfrac{15 + 1}{2}$

$= > 8$

8th term is median

Therefore, 23 is the median.
