The median of numbers $3,4,7,2,5,6,1,8,2,5,7$ is $5$.

The median of the numbers $3,75,10,81,17,27,4,48,12,47,9,15$ is $10$.

The mode of the scores $8,10,7,6,10,11,6,11,10$ is $11$.

The median of the numbers $3,5,0,4,9,7,6,2,8$ is $6$.

The variate value which occurs maximum number of times is called median of the distribution. 

The median of the scores $63,33,60,45,71,43,61,51,35$ is $51$.

In the given distribution, the modal class is $\left(89.5-99.5\right)$.
