Answer 2

Answer:

Median of marks obtained by 9 students is 15

Step-by-step explanation:

Given,

In an exam the marks obtained by 9 students are:19,15,18,14,12,13,11,16,17

First of all we arrange the marks in ascending order,

11,12,13,14,15,16,17,18,19

Here no.of observation (n)=9 which is an odd no.

So median = (n+1/2 )th term,

                  = (9+1/2)th term

                  = (10/2)th term

                  =5th term

Median=15
