Question

The median of the following data :

0,2,2,2,-3,5,-1,5,5,-3,6,6,5,6 is

• A. 0
• B. -1.5
• C. 2
• D. 3.5

Answer 1

The correct option is D

3.5

Arranging in ascending order, we get -3,-3,-1,0,2,2,2,5,5,5,5,6,6,6

Here n = 14 (which is even)

$\therefore$ Median $=\frac{1}{2}[\frac{n}{2}thterm+(\frac{n}{2}+1)thterm]$

$=\frac{1}{2}[\frac{14}{2}thterm+(\frac{14}{2}+1)thterm]$

$=\frac{1}{2}$[7th term + 8th term]

$=\frac{1}{2}(2+5)=\frac{7}{2}=3.5$
