Write the median class for the following frequency distribution:

Answer :

First, we prepare the cumulative frequency table for above data

We know that median class of a data is the class-interval corresponding to cumulative frequency just greater than


N = sum of all frequencies

As N = 100 therefore


Cumulative frequency just greater than 50 is 60 which lies corresponding to class 40-50

Hence, 40-50 is median class.
