Lab Five

Natural Breaks








Quantiles






Explanation of differences

Between the two data classification schemes, there is a difference in the choroplethic qualities found in the maps. In both maps, the concentration of higher value classes spreads out radially from one region of the country. But in the map that uses quantiles to classify its data, the standard distance as a measure of spatial variability is less than the map that uses natural breaks. The natural breaks map has a smoother transition from high value classes to low value classes.
