2. Explain what spatial auto-correlation means.
3. Describe the three patterns commonly identified in spatial autocorrelation tests.
   INSTRUCTIONS
   Scenario: Your friend is entirely confused after looking at the Lab 5 background material on Sakai. He

complains that this is not an epidemiology class, so why are we learning about diseases, anyway? Does

cholera causes spatial autocorrelation? Are patterns and processes related to cause and effect?

Prompt: Answer these three questions:

1. What does it mean to say a process is related to a pattern?
2. In the case of the London cholera map, what is the process and what is the pattern?
3. What are the three kinds of spatial or geographical patterns revealed by tests for spatial auto-

correlation?
