The marks obtained (out of $10$) by $40$ students are:

$6,1,7,3,4,2,4,5,6,4,8,3,0,2,3,2,3,3,3,7,9,5,5,8,6,1,2,4,4,0,1,5,9,4,8,1,2,7,3,7$

Array the data and form a frequency distribution table.

What is the highest mark?

The marks obtained by $40$ students are:

$6,1,7,3,4,2,4,5,6,4,8,3,0,2,3,2,3,3,3,7,9,5,5,8,6,1,2,4,4,0,1,5,9,4,8,1,2,7,3,7$

Array the data and form a frequency distribution table.

What is the range of marks?

The marks obtained by $40$ students are:

$6, 1, 7, 3, 4, 2, 4, 5, 6, 4, 8, 3, 0, 2, 3, 2, 3, 3, 3, 7, 9, 5, 5, 8, 6, 1, 2, 4, 4, 0, 1, 5, 9, 4, 8, 1, 2, 7, 3, 7$.

Which mark is obtained by most of the students?

Construct a frequency distribution table for the following ages of thirty students using equal class intervals, one of them being $9-12$ ($12$ not included)

$16,11,21,8,8,9,16,3,9,21,21,22,15,19,6,7,6,17,15,17,14,23,11,18,22,15,12,18,12,13$

The following data represent the number of books issued in a library over a period of $50$ days.

$\begin{array}{l}14,24,45,38,29,10,43,17,29,30,51,33,35,29,36,10,40,50,18,24,54,22,32,27,44,30,15,\\ 41,27,30,32,13,18,25,41,36,17,27,27,32,40,42,27,35,20,34,15,49,55,13\end{array}$

Form a frequency distribution table with grouping $10-20, 20-30, 30-40$ and so on.
