The ever increasing availability of computer programs and facilities leaves no question that a geologist can perform a factor analysis with little difficulty. Be cause of this ease, there is often a tendency to apply methods without fully understanding either the logic of the method or the 'more subtle question of what actually happens to the data at various stages during computation. These questions, although inextricably tied to the mathematics, can be more closely examined if one goes through the various stages in the analysis.
Few available texts on factor analysis focus their attention on these practical aspects. An exception is the book by Rummel (1970), in which factor analysis is presented as a problem in research design. 1e shall in this chapter outline points brought up by Rummel which are important to geological investigations, seasoned with comments from our own experience.
