QCC Heat and income in Baltimore Exercise

/ Uncategorized / By

Description

In 2019, two reports from the National Public Radio (NPR) investigated the relationship between heat and income in Baltimore. During their investigation, they interviewed a woman whose neighborhood, “Franklin Square, is hotter than about two-thirds of the other neighborhoods in Baltimore — about 6 degrees hotter than the city’s coolest neighborhood. It’s also in one of the city’s poorest communities, with more than one-third of residents living in poverty.”
Using data from the Census Bureau, NASA, and the U.S. Geological Survey, the reporters drew a map of surface air temperature and a map of median household income at the census tract level in Baltimore. The two maps are shown below. Census tracts are geographic areas drawn by the Census Bureau for the purposes of data collection in decennial census. Census tracts are widely used as proxies for neighborhoods.
Question 1. Create a theory that explains the relationship between surface air temperature and median household income across the neighborhoods in Baltimore. (2 points)
Question 2. What hypothesis (or testable proposition) can you generate from this theory? 
Question 3. What is the dependent variable in your hypothesis? What is the independent variable in your hypothesis? 
Question 4. Does the data shown in the graph above provide evidence supporting your hypothesis? Why or why not? 
Question 5. Does the data shown in the graph above prove your theory? Why or why not? (Hint- Theory and Hypothesis are not the same thing.)
