Question

1. identify the distribution of the deaths? what is the distribution of the dead? are they dispersed all over the map evenly, or are there clusters of dead in certain areas? if clustered, where are clusters of cases occurring? (layer 2 - what do you notice?) 3. identify the spatial patterns. are there any clear spatial patterns to the phenomena? do you see any linear patterns (in a line)? any circular patterns (radiating out from a point/node)? (layer 2 - what do you notice?) 4. from your spatial analysis, identify the absolute location of the of the origin of the disease (specific location) and explain in detail why you think so? (layer 3 - can you explain the patterns?) 5. identify the limitations that are presented by the data. where are the outliers (exceptions) that possibly challenge your suspected source? these are places where “people should have died, but didn’t, and places where people shouldn’t have died, but did.” (layer 2 - what do you notice?)

Explanation:

1. Check map for even or clustered death - spots.
2. Look for linear or circular spatial patterns.
3. Determine disease origin by spatial analysis.
4. Find data outliers challenging origin theory.

Answer:

1. Analyze map for distribution.
2. Identify spatial patterns.
3. Determine origin, explain patterns.
4. Identify data limitations.
