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 5th 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 5th 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 6th 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 7th term


Median = 4
