Gapminder
Think about what might account for diering levels of happiness across countries. Go to
Gapminder World (https://www.gapminder.org/tools/), select the Y (vertical) axis,
and select Happiness score (WHR) under the Society category. What do you think would
correlate with this measure, internationally? Scan the available data on the X axis and
try out a couple variables.
Make sure to select a variable for which there is data on
enough countries on a long enough time period. Select one of the variables you looked
at and evaluate the relationship between that variable and happiness. Why do you think
you might be seeing those patterns in the data? Use the links button to create a short
URL to your graph. Along with this link, write 1-2 paragraphs describing the patterns
you see in the data and speculating about what might have produced them. (3 points)
Datawrapper
Download a CSV le of the variable you compared to Happiness in the question above.
(On the Gapminder page, go to Facts Data and type in the name of the variable
you selected.) Use this dataset and Datawrapper (https://www.datawrapper.de/) to
generate a Choropleth map of the world. Select a recent year for which most countries
have values and correct the names of unmatched countries.
What year did you select
and what is the variation for you chosen variable around the world in that year? Does
there appear to be any geographic clustering of values or are the randomly spread across
the glob.
Include a screenshot of you map and write 1-2 paragraphs describing the
visualization and answering the questions. (4 points)
