Question

Write the median class of the following distribution:

Class	0 – 10	10 – 20	20 – 30	30 – 40	40 – 50	50 – 60	60 – 70
Frequency	4	4	8	10	12	8	4

Answer 1

To find median let us put the data in the table given below:

Now, = 50 ⟹ \(\frac{N}2\) = 25 

The cumulative frequency just greater than 25 is 26, and the corresponding class is 30 - 40. Thus, the median class is 30 - 40.
