The Use of Computational Diagrams and Nomograms in Higher Education.
Brandenburg, Richard K.; Simpson, William A.
AIR Professional File, n17 Sum 1984
The use of computational diagrams and nomographs for the calculations that frequently occur in college administration is examined. Steps in constructing a nomograph and a four-dimensional computational diagram are detailed, and uses of three- and four-dimensional diagrams are covered. Diagrams and nomographs are useful in the following cases: (1) wherever a routine calculation must be performed repeatedly, using different input values; and (2) in planning where a relatively simple analytical model is needed to calculate responses to "what if" questions posed in the form of values assigned to input variables. The nomograph involves a set of numerical scales calibrated along straight lines that are usually parallel. Nearly any calculation that can be represented by a computational diagram can also be represented by a nomograph, or conversely. In general, nomographs work best when the number of variables is less than six and the mathematical relationships are relatively simple. It is claimed that computational diagrams and nomographs not only equal the performance of a microcomputer, they are more convenient to use and can be used by all participants in planning sessions. Applications of these approaches for modeling departmental workloads and for an instructional model of a department are illustrated. (SW)
