Write the median

Answer :

To find median class,

Assume Σfi = N = Sum of frequencies,


fi = frequency


and Cf = cumulative frequency


Lets form a table.



So, N = 50


N/2 = 50/2 = 25


The cumulative frequency just greater than (N/2 = ) 25 is 26, so the corresponding median class is 30 - 40.


Hence, median class = 30 - 40
