Question

Median of the data: $1,9,4,3,7,6,8,8,12,15$ is.

• A. $6.5$
• B. $7.5$
• C. $8$
• D. Any number between $7$ and $8$

Answer 1

Answer: (B)

$7.5$

First arrange the set of data in order(from least to highest)

$1,3,4,6,7,8,8,9,12,15$

As there are even number of items,

$\therefore$ Median $=\frac{7+8}{2}=\frac{15}{2}=7.5$
