Question

Find the difference between the mean and the median of the set $3,8,10,15$.

• A. $0$
• B. $1$
• C. $4$
• D. $9$

Answer 1

The correct option is A $0$

Given set is $3,8,10,15$

We have even number of term so median is $8$ and $10$

Then average of the middle term $=$ $\frac{8+10}{2}=\frac{18}{2}=9$

$\therefore$ Median $=9$

Mean $=\frac{3+8+10+15}{4}=\frac{36}{4}=9$

Difference between mean and median $=$ $9-9=0$
