Answer :

A) Mean =


Total area of all deserts = 8800000 + 1300000 + 1250000 + 850000 + 580000 + 370000 + 320000 + 310000 + 310000 + 260000 = 14350000


= []


= 1435000 km2


Median = []


= []


=


=


= 475000 km2


Mode = Most frequent observation = 310000 km2


B) Let the size of Gobi desert is x times the Namib desert


Gobi desert = x × Namib desert


1300000 = x × 310000


x =


= 4.19


C) Total number of deserts = 10


Number of deserts in Asia = 5


percentage of deserts in Asia = × 100% = 50%


D) Total area of all deserts = 14350000 km2


Total area of Asia’s deserts = 1300000 + 850000


= 3040000 km2


percentage of the total area of the deserts listed in Asia =


= × 100%
