$41,39,48,52,46,62,54,40,96,52,98,40,42,52,60$

Find the mean, median and mode of this data.

The marks of $15$ students is

$41,39,48,52,46,62,54,40,96,52,98,40,42,52,60$

Mean $=1541+39+48+52+46+62+54+40+96+52+98+40+42+52+60 $

$=15822 =54.8$;

Number of observations $=15$ (odd)

Median score $=8$th number arranging in ascending order which is $52.$

Maximum frequency $=3$ of $52$

$∴$ Mode $=52.$.
