Question 23
Median of the following numbers
4, 4, 5, 7, 6, 7, 7, 12, 3 is:

A) 4
B) 5
C) 6
D) 7

Answer 1

The answer is C.
First, we arrange the given numbers in ascending order as,
3, 4, 4, 5, 6, 7, 7, 7 and 12.
Here, n = 9
Since n is odd, we use the formula for the median.
Now,
$median=\left(\frac{n+1}{2}\right)$th observation
$=\left(\frac{9+1}{2}\right)$th observation
$=\left(\frac{10}{2}\right)$th observation = 5th observation = 6
Hence, median of the given numbers is 6.
