Question

find the median :

question 1= 3 , 11 , 7 , 2 , 5 , 9 , 9 , 2 , 10 ​

Answer 1

Answer:

Step-by-step explanation:

The value of the middle-most observation is called the median of the data.

First arrange the given numbers in ascending order,

2,2,3,5,7,9,9,10,11

Here n=9, which is odd.

Where, n is the number of the given number.

∴ median = value of  

2

1

​  

(n+1)  

th

 observation.

=  

2

1

​  

(9+1)

=  

2

1

​  

(10)

=10/2

=5

Then, value of 5  

th

 term =7

Hence, the median is 7.

Answer 2

Answer:

Arranging the data in ascending order, we have : 2, 2, 3, 5, 7, 9, 9, 10, 11. Here, n = 9, which is odd. ∴ Median = Value of term.
