household with monthly income of 1500 is added, what will the median income be?
​

Answer 1

Answer:

1.Arrange the income in ascending order :

1000,1000,1200,1400,1500,1600,10000

This is the income of 7 households.The median is always the middle value.Here there is 7 values and the middle value is the 4th value .ie.1400

So Median(Me)= 1400

2.If one more household is added then in ascending order:

1000,1000,1200,1400,1500,1500,1600,10000

Now there is two middle terms.4th and 5th term

Therefore: Median=(1400+1500)/2

=1450
