how to find the median class?
Steps to find the median class are as follows:
1. Arrange the class intervals in increasing order.
2. Write down the cumulative frequencies.
3. Find the value of n/2 or (n+1)/2.
4. See the equal or greater but nearest value to n/2 or (n+1)/2 in cumulative frequency column.
5. The corresponding class to that cumulative frequency will be median class.
