Question

A boy scored the following marks in various class tests during a term, each test being marked out of $20.15, 17, 16, 7, 10, 12, 14, 16, 19, 12, 16.$What is his median marks?

✓

Answer

Arranging the given marks in ascending order, $7,10,12,12,14,15,16,16,16,17,19$
Here $N =11$
$\therefore$ Median is $\left(\frac{ N +1}{2}\right)^{\text {th }}$ term
$=\left(\frac{11+1}{2}\right) $
$=6^{\text {th }}$ term
$\therefore$ Median marks $=15$.
