Transcript of GEOG 3P47 Mapping Stats Colleen Beard Map & Geography Librarian Room MC C306 [email protected].
Why map data?
• Basis for statistical mapping:Any kind of data that can be expressed numerically and varies in quantity from place to place can be mapped.
Statistical mapping requires two criteria:– Data has a numeric value– Data has a geographic element
• Choropleth maps are very useful tools for representing numeric data (population density; percentages; location quotients)
