Median

The median is defined as the positional value in the set of data arranged in order. The median divides the total number of observations into two equal parts. Therefore, there are 50% items more than the median value. 

sf

Calculation of median in continuous series

Steps to be remembered

a. Arrange the data in ascending order of magnitude.

b. Construct the cumulative frequency distribution table.

c. Find the median class by using 

Median class = (\(\frac{N}{2}\))th class

d. Then find exact median value by using 

\( M_d = L + \frac{\frac{N}{2}- c.f.}{f} \times h \)

Where,
L = lower limit of the class
c.f. = cumulative frequency of preceding class 
f = frequency of class
h = width of class-interval
