The weekly wages (in Rs.) of 30 workers in a factory are:
830, 835, 890, 810, 835, 836, 869, 845, 898, 890, 820, 860, 832, 833, 855, 845, 804, 808, 812, 840, 885, 835, 835, 836, 878, 840, 868, 890, 806, 840.
Using tally marks make a frequency table with intervals as 800 - 810, 810 - 820 and so on....
Also draw the histogram for the frequency table made.


Given: Weekly wages (in Rs.) of 30 workers.


To do: Here we have to make a frequency table and also draw the histogram for the frequency table made.



Solution:

Taking intervals as 800 - 810, 810 - 820 and so on....

Frequency table of the given data:

Wages (in Rs)No. of workers
800-810

        III

810-820        II
820-830        I
830-840        IIII IIII
840-850       IIII
850-860      I
860-870      III
870-880      I
880-890      I
890-900      IIII

So, histogram of this data is as below:
