The value of $\pi$ up to $35$ decimal places is given below:
$3.14159265358979323846264338327950288$
Make a frequency distribution table of the digits $0$ to $9$ after the decimal point.

The following is the distribution of the number of employees working on different floors of the six-storey commercial complex:

Floor	$1$	$2$	$3$	$4$	$5$	$6$
Number of employees	$51$	$48$	$42$	$44$	$48$	$32$

Represent the information above by a bar graph.

The range of the observations: $7, 9, 7, 5, 6, 6, 9, 18, 8, 8, 6$ is ..........

The information regarding the marks scored by $30$ students in a $50$ marks test is given below:

Marks $(x_{i})$	$15$	$22$	$28$	$31$	$35$	$40$	$44$	$46$
Number of students $(f_{i})$	$2$	$3$	$5$	$6$	$6$	$4$	$3$	$1$

Find the mean of the data.

For drawing a frequency polygon of a continuous frequency distribution,we plot the points whose ordinates are the frequencies of the respective classes and abscissae are respectively:

The following are the marks (out of $100$) of $60$ students in mathematics:
$16, 13, 5, 80, 86, 7, 51, 48, 24, 56, 70, 19, 61, 17, 16, 36, 34, 42, 34, 35, 72, 55, 75, 31, 52, 28, 72, 97, 74, 45, 62, 68, 86, 35, 85, 36, 81, 75, 55, 26, 95, 31, 7, 78, 92, 62, 52, 56, 15, 63, 25, 36, 54, 44, 47, 27, 72, 17, 4, 30$
Construct a grouped frequency distribution table with a class width of $10$,such that one of the classes is $10-20$ ($20$ not included).
