Question
From the following numbers find the median:
10, 75, 3, 81, 17, 27, 4, 48, 12, 47, 9, 15.
Solution
On arranging in ascending order
3, 4, 9, 10, 12, 15, 17, 27, 47, 48, 75, 81
Here, n = 12 which is even
Therefore, median = `(("n"/2)^"th" "term" + ("n"/2 + 1)^"th" "term")/(2)`
= `((12/2)^"th" "term" + (12/2 + 1)^"th" "term")/(2)`
= `(6^"th" "term" + 7^"th" "term")/(2)`
= `(15 + 17)/(2)`
= `(32)/(2)` = 16
Median = 16.
