1. The relationships between average income levels (GDP per capita and the two measures – fertility and infant mortality

The scatter plot shows the relationship between Birth Rate (dependent, Y variable) and GDP per capita (Independent, X variable) in selected countries hence demonstrates a rough negative relationship between the two.   This means that as the income of women increases, the birth rates would decline. Moreover, this graph shows non-linear relationship between birth rate and the GDP per capita. The outliers are circled; however we believe that this is not due to any errors.

Dependent variable (Y) is Birth Rate (per 1,000 people).

Independent variable (X) is GDP per capita (current US\$).

The scatter plot shows the relationship...
