AIM
The aim of this project is to determine the statistical correlations between two indicators by using Spearman’s correlation coefficient. This is a statistical measure that shows the strength of a relationship between both variables. When written in mathematical notation the Spearman Rank formula looks like this:


Fifteen is the minimum number needed in a sample for Spearman rank rule to be valid. However, to achieve a greater level of accuracy, I will be collecting data for twenty-five countries in this assignment. The measured variables will be:
· The relationship between the percentage of population with access to improved drinking water source and infant mortality rate.
· The relationship between the percentage of population with...
