Identify the five largest cities within
each country: Johannesburg, Cape Town, Durban, Pretoria, Port Elizabeth
Identify the population of the
largest city: 7,860,781
Use the “rank size rule” to identify
the estimated size of each of the
next four largest cities (city #2 is ½
the size of city #1, city #3 is 1/3 the
size of city #1, city #4 is ¼ the size
of #1, city #5 is 1/5 the size of #1): 3,930,390, 2,620,260, 1,965,000, 1,572,160
Identify the actual populations of
the 2nd, 3rd, 4th, & 5th largest cities: 3,430,992, 2,786,046, 1,763,336, 876,436
Compose a well-developed
paragraph defending to what extent
the “rank size rule” is proven valid
or invalid based upon the
populations of this country’s five
largest cities: The rank size rule could very well fit this set of data for the population of South Africa. In order for the rank size rule to be valid, the predicted populations must be within a few thousand people of the actual population. In the case of South Africa, the predicted values and actual values are very similar for the most part, thus the rank size rule does apply for this country.
