Question

The median of the numbers 4, 4, 5, 7, 6, 7, 7, 12, 3 is
(a) 4
(b) 5
(c) 6
(d) 7

Answer 1

(c) 6

We will arrange the given data in ascending order as:
3, 4, 4, 5, 6, 7, 7, 7, 12
Here, n is 9, which is an odd number.
Thus, we have:
$$\begin{gathered} \mathrm{Median}=\mathrm{Value}\mathrm{of}\frac{1}{2}(n+1)\mathrm{th}\mathrm{term} \\ \mathrm{Median}\mathrm{score}=\frac{1}{2}(9+1)\mathrm{th}\mathrm{term}=5\mathrm{th}\mathrm{term}=6 \end{gathered}$$
