Explanation / Answer

Mean = Sum of observations / Total number of observations

= (34,000 + 46,000 + 69,000 + 4,00,000 + 59,000 + 45,000 + 64,000) / 7 = 7,17,000/7 = $ 1,02,428.57

Median = (N+1)/2 th term = (7+1)/2 = 4th item but firstly arrange the data is ascending or descending order:

34,000 ; 45,000 ; 46,000 ; 59,000 ; 64,000 ; 69,000 ; 4,00,000

So, median is $ 59,000 i.e. 4th item.

Mean because it corporates every individual in the economy.
