Task: Crude oil contains many of the crucial compounds used in transport fuel. American dependence on foreign crude oil has reduced due to an increase in collection of natural gas in its own borders. This has had many knock-on effects. Look at the graphs (Tylervigen.com, 2016) and answer the questions below them:
1. Is there a correlation between the two factors?
2. Try to think of a mechanism to explain the correlation (you may have to be a little creative).
3. Is your suggested "mechanism" enough to establish a causal relationship?

3. Is your suggested "mechanism" enough to establish a causal relationship?
4. Can you explain the correlation in this graph?
5. Is this mechanism sufficient to support a causal relationship?
6. Do things that correlate always have a causal relationship?
