Question

Median of a data set is a number which has an equal number of observations below and above it. The median of the data $1,9,4,3,7,6,8,8,12,15$ is

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

Answer 1

The correct option is A $7.5$

The data given here is: $1,9,4,3,7,6,8,8,12,15$
After arranging in ascending order $1,3,4,6,7,8,8,9,12,15$
Since the number of terms are even, median $=\frac{4^{th}+5^{th}}{2}$
$=\frac{7+8}{2}$
$=\frac{15}{2}$
$=7.5$
Hence, option $A$ is correct.
