3 Spatial analysis framework
Frame your question Understand your data Choose your methods Process your data Review your results

4 A sample analysis

5 Analysis 1 Question: What is the distribution of population changes between CY2000 and CY 2010? Data: US Counties, Census information for 2000, 2010 Method: Calculate the difference in population county-by-county Perform: Use the Field Calculator PopulationChange = CY2010 – CY2000 Review:

6 Analysis 2 Question: What is the distribution of normalized population changes between CY2000 and CY 2010? Data: US Counties, Census information for 2000, 2010 Method: Calculate the difference in population county-by-county Perform: Use the Field Calculator PopulationChange = (CY2010 – CY2000) / (CY CY2000) Review:
