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
