Using GapMinder ( http://www.gapminder.org/ ) for Presentations

Professor Hans Rosling has created a wonderful website, GapMinder ( http://www.gapminder.org/ ) so that anyone with access to computers and the Internet can play with statistics. First, please watch this YouTube video => http://www.youtube.com/watch?v=jbkSRLYSojo (this is the same as (4/6) below). The longer version of this is available here => (1/6) http://www.youtube.com/watch?v=en2ix9f8ceM (2/6) http://www.youtube.com/watch?v=hUGUWr-TjR8 (3/6) http://www.youtube.com/watch?v=yhX0OR1_Vfc (4/6) http://www.youtube.com/watch?v=ahp7QhbB8G4  ; (this is the same as the above) (5/6) http://www.youtube.com/watch?v=6RzDMEW5omc (6/6) http://www.youtube.com/watch?v=AEac-jP5Eho

This exercise asks you to create a graph of correlation of your own. First, go to GapMinder ( http://www.gapminder.org/ ). Click on the GAPMINDER WORLD tab (next to HOME). When you open the tab, the default graph is uploaded, which plots the relationship between GDP per capita (PPP$, inflation adjusted) and life expectancy in years. You can change the variables on horizontal and vertical axes.

You have to present your theory of economic growth.  Because we want to explain economic growth, the variable for the vertical (Y) axis must be either "income per person (GDP/capita, PPP $ inflation adjusted)" or "GDP/capita growth (% per year)."  After choosing your Y variable to explain, choose a variable for the horizontal (X) axis from the drop-down list and create a new graph of a relationship. After you create a graph, click “ Share graph.” A small pop-up window opens, which tells you to “Copy the short link below and paste it in a blog or send it by e-mail.”& & & & & & &   Copy and paste the link of your graph to this discussion board and share your graph.

After you pasted the link, explain to the class (i) which two variables you selected, (ii) why do you think the relationship between your X-variable and the Y-variable are important and/or interesting in explaining economic growth (e.g., your theory of economic growth), and (iii) whether the observed relationship is "causality" (i.e., the x-variable causing the y-variable) or mere "correlation."

When you have time, please try to watch as many videos on GapMinder as possible.  You will learn a lot about economics and epidemiology.
