Consider the following statements:
1. Climate and availability of water largely determines the pattern of the population distribution.
2. Density of population helps in getting a better understanding of the spatial distribution of population in relation to land
Which of the statement(s) given above is/are correct
Calculate the population density of Nigeria, having a total population of 180 million with a total land area of 923,768 sq km?
Total population = 180,000,000
Total land area = 923,768 sq km
Population density = (Total population) / (Land area)
=180,000,000/923,768
=194.85
=195 persons per sq km

What is the median of the distribution?
For a group data we us cumulative frequency: Median=[(N+1)/2]th
For member of odd number items. That is, where N is odd
Median=([N/2]th + [N/2 + 1]th)/2
For member of odd number items. That is, where N is odd
Solution:
From the table, there are 20 members as indicated by the cumulative frequency. Since the members are odd (10) the median age will be ([N/2]th + [N/2 + 1]th)/2
Median=([10/2]th + [10/2 + 1]th)/2
=(5th + 6th)/2
The 5th member is 3 and the 6th member is on 3
Median=(3 + 3)/2
=6/2
Median = 3
