The data given below shows the number of people who have saved a certain amount of money.
What is the median of the given data?
Solution
Re-writing the given data in the form of a series
Number of people who save Rs.5 = 1 --> 5
Number of people who save Rs.15 = 3 --> 15,15,15
Number of people who save Rs.20 = 4 --> 20,20,20,20
Similarly, Writing all the numbers in the form of series
5,15,15,15,20,20,20,20,25,25,30,35,40,40
Here, The middle values are 20,20
Median = $$\dfrac{20+20}{2} = \dfrac{40}{2} = 20$$
