Visualizing the Happy Planet Index The figure below shows a scatterplot illustrating three different variables from the dataset HappyPlanetIndex. The variable Happiness is a measure of the well-being of a country, with larger numbers indicating greater happiness, health, and well-being. The variable Footprint is a per capita measure of the ecological impact of a country on the environment, with larger numbers indicating greater use of resources (such as gas and electricity) and more damage to the planet. A third variable, Region, is given by the code shown in the top right, and is categorized as follows: 1 = Latin America, 2 = Western nations, 3 = Middle East, 4 = Sub-Saharan Africa, 5 = South Asia, 6 = East Asia, 7 = former Communist countries.

Transcript

00:01 For this problem, we are given some background information, but what we really care about is that we have a scanner plot shown here with three different variables.

00:08 Ecological footprint, happiness, and region, where each region is classified from latin america through to former communist countries.

00:18 In part a, we're asked to classify each of the three variables as categorical or quantitative.

00:23 You can see that ecological footprint is quantitative, happiness is quantitative here, and the region is categorical, which i'm specifying as cat.

00:35 For part b, we are asked, which two regions seem to have the greatest happiness score, which region seems to have the greatest ecological footprint? so we want to look along here.

00:46 We can see that it would appear, region one and region two have the highest happiness scores.

00:54 So i'll specify that one and two for the first part of the, of the, of, part b.

01:01 And then for which seems to have the greatest ecological footprint, region two.

01:09 For part c, we are asked which region seems to have the lowest happiness score, and does the ecological footprint tend to be high or low in that area? so we can see that our right side up blue triangles, so that's region four, seems to have the lowest happiness score and also has the lowest ecological footprint.

01:26 So it is region four and low ecological footprint in that area.

01:34 Then for part d, we are told that, or we are asked, looking at the scatterplot overall and ignoring region, does there appear to be a positive relationship between happiness score and ecological footprint? we can see that, roughly speaking, yes, there is a positive relationship.

01:51 For part e, we are asked, considering only region two, western nations, does there appear to be a positive relationship between happiness score and ecological footprint? so western nations are just the black dots...
