Session goals Review definition of global health Contrast global nutritional dilemmas- hunger vs obesity, infectious diseases (children) and chronic diseases (adult) Investigate data sources, pose preliminary problem Test hypotheses Present short ppt of findings
Are there data to help us begin to research relationships? Global US • Gapminder • UNICEF • CIA • Lots more • USDA, Food Environment Atlas, http://ers.usda.gov/foodatlas/ • Behavioral Risk Factor Surveillance Survey • Local mapping Gallons of soft drink per capita, by county 2008, Source: USDA Food Atlas
Maps and graphs as starting points for problem posing Maps tell stories, but what are their limits What statistics are behind the maps and how do we analyze them? (1-3, 16 to end)
Gapminder’s stories: Beware correlation vs causation Relationship between growth in per capita income and infant mortality Relationship between net production of crops per capita and infant mortality
The challenge of analysis Make a graph Analyze correlation • Import data into Excel • What kinds of graphs illustrate your findings best • How can you label the graph to communicate your findings? • (IS THIS A TWO-SENTENCE GRAPH?) Make sure that dependent variable is on Y axis. • Import data into JMP or SAS to analyze relationships
