Find the median of

(i) 2, 10, 9, 9, 5, 2, 3, 7, 11

(ii) 15, 6, 16, 8, 22, 21, 9, 18, 25

(iii) 20, 13, 18, 25, 6, 15, 21, 9, 16, 8, 22

(iv) 7, 4, 2, 5, 1, 4, 0, 10, 3, 8, 5, 9, 2

(i) By arranging the data in ascending order

We have;

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

N = 9 (Odd number)

Median = value of the term

= value of 5^th term

Median = 7

(ii) By arranging the data in ascending order

We have;

6, 8, 9, 15, 16, 18, 21, 22, 25

N = 9 (0dd number)

Median = value of the term

= value of 5^th term

Median = 16

(iii) By arranging the data in ascending order

We have;

6, 8, 9, 13, 15, 16, 18, 20, 21, 22, 25

N = 11 (Odd number)

Median = value of the term

= value of 6^th term

Median = 16

(iv) By arranging the data in ascending order

We have;

0, 1, 2, 2, 3, 4, 4, 5, 5, 7, 8, 9, 10

N = 13 (Odd number)

Median = value of the term

= value of 7^th term

Median = 4
