  1. Units of Analysis, Maps, and Scale Dr. Roy Cole SS300 Research Methods

  2. The unit of analysis • The unit on which data are collected. • The “what” or “whom” that is being studied. • The unit on which a conclusion is to be made. • The UOA may be disaggregated or aggregated. • The unit of analysis may be different from the unit of observation.

  3. The unit of analysis • Individuals. • Groups. • Artifacts (books, photos, newspapers) • Geographical units (town, census tract, state). • Social interactions (dyadic relations, divorces, arrests).

  4. Types of scale • Large-scale maps. • Representation “closer” to the ground. • Houses, fields, etc. can be depicted. • 1:250,000 and below is large scale. • Four miles to the inch. • City maps, real estate (cadastral) maps, construction maps.

  5. Types of scale • Medium scale maps. • Road maps, airway maps. • 1:250,000 to 1:1,000,000. • 4 to 16 miles per inch.

  6. Types of scale • Small scale maps. • Above 1:1,000,000. • Used in atlases, books, and magazines.
