kritika3375

Step-by-step explanation:

Arranging in ascending order

2 , 4 , 7 , 9 , 11 , 15

No of data (N) = 6

Now

Position of median

= (N+1)/2 th item

= ( 6 + 1) /2 th item

= 7/2 th item

= 3.5 th item

Exact Median

= 3 + 0.5 ( 4th term - 3rd term)

= 3 + 0.5( 9 - 7)

= 3 + 0.5 * 2

= 3 + 1

= 4

Hope it will help :)
