Answer 1

Answer:

In a survey to find out the living standards of the people in the city, the monthly income of 5 randomly chosen households were obtained.

Household 1 2 3 4 5

Income (in ₹) 2,00,000 1,50,000 1,20,000 15,00,000 1,10,000

The mean income of these households is ₹4,16,000. However, we observe that 4 out of 5 households have income below ₹4,16,000. This value gives a distorted picture of the standard of living of the people in the city because one household has an extremely high income. To obtain a more accurate representation of the data, one way is to use another type of average called the median. The median is the middle value when the data is arranged in ascending or descending order.
