Question

The median of the data : 4,4,5,7,6,7,7,12,3 is

(a) 4
(b) 5
(c) 6
(d) 7

Answer 1

Arranging the data in ascending order, we have

3, 4, 4, 5, 6, 7, 7, 7, 12

Here, the number of observations n = 9, which is odd

∴ Median = Value of $\left(\frac{9+1}{2}\right)\mathrm{th}$ observation = Value of $\left(\frac{10}{2}\right)\mathrm{th}$ observation = Value of 5th observation = 6

Thus, the median of given data is 6.

Hence, the correct answer is option (c).
