Discussion
Consider the following statements about area-based thematic data.
1. The modifiable areal unit problem has both a scale and a zoning component.
2. The ecological fallacy concerns inferences drawn about individuals.
3. Both problems disappear if enough classes are used in the legend.
Answer: A
Correct answer: 1 and 2 only
Statements 1 and 2 are correct: the modifiable areal unit problem has a scale component, from the size of the units, and a zoning component, from where their boundaries are drawn; and the ecological fallacy is the error of inferring something about individuals from an area aggregate. Statement 3 is wrong - both problems arise from the units themselves, before any classification is applied, so no legend design can remove them.
