Unstandarized Choropleth Maps

Unstandarized choropleth maps are maps where the data has not been averaged. The data is presented in numerical values. This particular map shows the number of hazardous waste site installations per state in 1997. Since these numbers are raw numbers; it is an unstandarized map. The choropleth map is broken into 6 equal step intervals. The legend is present at the bottom of the map. The different colors represent different values of waste site installations. This map was found at http://www.okstate.edu/sas/v7/sashtml/books/graph/images/01215109.gif.
