Arrange the data in ascending or descending order
Find the median value
Identify the cumulative frequency just greater than or equal to the median position
Use the formula for median position: N/2
Locate the class interval where the cumulative frequency first reaches or exceeds N/2
The corresponding class is the median class
The cumulative frequency before the median class is the CF used in the median formula
Use CF in the median formula as the cumulative frequency of the class preceding the median class
