Q. 12
Write the median class of the following 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 
Where,
N = sum of all frequencies
As N = 25 therefore 
And
Cumulative frequency just greater than 25 is 26 which lies corresponding to class 30-40
Hence, 30-40 is median class.
