Draftsman Displays, A Graphical Technique for Exploratory Data Analysis.
Abstract
This thesis develops and explores the graphical analysis of multivariate data sets through the use of a Draftsman technique of scatter plot displays. These plot displays are useful for determining associations and relationships between variables in order to promote an understanding of the characteristics of the data in exploratory and descriptive applications. General graphical enhancement techniques such as jittering and transformations are discussed and incorporated in the development of a computer program which produces Draftsman displays. A technical description of the Draftsman computer program is presented, and user implementation procedures discussed. An analysis is conducted on two varied sets of data to demonstrate the versatility and utility of the Draftsman display technique for exploring data structures.
