The marks of 30 s

Answer :

Given are marks of 30 students of a class, obtained in a test (out of 75).

Note that these marks lie between 0 to 75.


So, these should be distributed in a way such that, the interval remains same in each distribution.


If we distribute it in a class interval equals to 5. Then, range would get maximized, i.e., 0-5, 5-10, 10-15, 15-20, …, 70-75.


But if we distribute it in a class interval of 10. Then the range will be optimized.


So, let’s make a table.



Thus, this is the required frequency distribution table.
