With the advent of the computer and user-friendly statistical software packages, factor analysis has become accessible to most researchers. However, conventional factor analysis, or R-technique, is only useful for research concerning types or groups of variables. Educational and psychological researchers are often interested in types of people, and R-technique is often incorrectly used in these research situations. However, appropriate factor analytic models exist to address research questions related to people, occasions, or other entities. This paper discusses the six basic factor analytic models and when they are appropriate, and it cites specific examples with the research questions they addressed. The six models discussed are: (1) R-technique, the usual factor analysis; (2) Q-technique, used for assessing types of people or groups of people; (3) P-technique, used to show changes in scores for the same person at different times; (4) O-technique, used to identify similarities in occasions for a particular individual; (5) S- technique, used to factor individuals across occasions; and (6) T-technique, used to factor occasions across individuals. The research situation and the research questions should determine the choice of factor analytic technique. (Contains 1 figure, 3 tables, and 24 references.) (Author/SLD)
