How many workers are getting $\mathrm{₹} 350 ?$

Following figures relate to the weekly wages (in $₹$) of $15$ workers in a factory:

$300,250,200,250,200,150,350,200,250,200,150,300,150,200,250$

Prepare a frequency table.

What is the range in wages (in $\mathrm{₹}$)?

Prepare a frequency table of the following ages (in years) of $30$ students of class VIII in your school:

$\mathrm{13,14,13,12,14,13,14,15,13,14,13,14,16,12,14,13,14,15,16,13,14,13,12,17,13},\mathrm{12,13,13,13,14}$

In a study of number of accidents per day, the observations for $30$ days were obtained as follows:

$6,3,5,6,4,3,2,5,4,2,4,2,1,2,2,0,5,4,6,1,6,0,5,3,6,1,5,5,2,6$

Prepare a frequency distribution table.

A die was thrown $25$ times and following scores were obtained:

$1,5,2,4,3,6,1,4,2,5,1,6,2,6,3,5,4,1,3,2,3,6,1,5,2,$

Prepare a frequency table of the scores.

Prepare a frequency table of the following scores obtained by $50$ students in a test:

$42,51,21,42,37,37,42,49,38,52,7,33,17,44,39,7,14,27,39,42,42,62,37,39,67,51,$
