Concept explainers
a.
Identify the three variables in Figure 2.86 as categorical or quantitative.
b.
Identify the two regions that seem to have the greatest happiness score.
Identify the two regions that seem to have the greatest ecological footprint.
c.
Identify the region that seems to have the lowest happiness score.
Check whether the ecological footprint tends to be high or low in that area.
d.
Identify whether there is a positive relationship between happiness score and ecological footprint by ignoring the region.
e.
Identify whether there is positive relationship between happiness score and ecological footprint by considering only region 2.
f.
Indicate whether Country CR is in the top left, top right, bottom left, or bottom right of the scatterplot.
g.
Identify the variables to be focussed to move more countries to the top left of the scatterplot, the countries in region 4.
Explain whether that variable has to increase or decrease.
