Introductory college level geography textbooks can be enhanced by using scatter diagrams and double criteria classifications, both of which reveal generalizations and specific facts about location. Scatter diagrams, a series of dots on a graph, illustrate relationships among phenomena that covary, e.g., national birth and infant mortality rates. According to the density or sparseness of the dots, scatter diagrams simultaneously present generalizations and identify exceptions and deviations. The diagrams may be supplemented with maps so that points on the graph are represented by geographic locations. Double criteria classification involves classifying a population of individuals according to the two criteria indicated by each axis on a scatter diagram. For example, the birth and infant mortality rates for a specific country can be charted on two separate maps for a side-by-side comparison. Each of these basic methods communicate information about human geography often lacking in geography texts. Examples of each graphic aid are included. (KC)
