Question

On $13$ consecutive days the number of person booked for violating speed limit of $40$ km/hr. were as follows $59,52,58,61,68,57,62,50,55,62,53,54,51$.
The median number of speed violations per day is

• A. $61$
• B. $52$
• C. $55$
• D. $57$

Answer 1

The correct option is D $57$

$\Rightarrow$ In the above given data $62$ is repeated twice,

$\Rightarrow$ Now we write the data in ascending order.

$\Rightarrow$ $50,51,52,53,54,55,57,58,59,61,62,62,68$

$\Rightarrow$ Thus, the measure of $\frac{13+1}{2}=7th$ number is median value.

$\therefore$ The median number of speed violation per day is $57$.
