Question

What is the median of the following set of numbers: 14, 17, 11, 17, 12, 13, 13, 14, 19, 25, 22, 18, 11, 23, 9 Select one: A. 11 B. 13 C. 14 D. 18

Answer 1

Order numbers from least to greatest and answer is the middle number

Answer 2

Answer: C. 14

Step-by-step explanation:

The given data : 14, 17, 11, 17, 12, 13, 13, 14, 19, 25, 22, 18, 11, 23, 9

To find median, first we arrange it in ascending order as

$9,\:11,\:11,\:12,\:13,\:13,\:14,\:14,\:17,\:17,\:18,\:19,\:22,\:23,\:25$

Number of data values n=15 (odd)

It means,

The median value = $\dfrac{n+1}{2}th\ term=\dfrac{15+1}{2}th\ term=8th\ term=14$

Hence, the median value = 14
