The purpose of the study was to analyze the personality traits of an individual as measured by a standardized personality test instrument and the vocational interest patterns as measured by a standardized vocational interest test. An attempt was made to determine if these identifiable personality traits were related to the ten reordered vocational clusters by means of a simple analysis of variance technique. In order to achieve this purpose, the following hypothesis was developed for investigation: There would be significant differences among the ten vocational clusters identified by the SVIB (Technical Cluster, Intellectual Cluster, Scientific Cluster, Business Cluster, Social Service Cluster, Creative Cluster, Office-Clerical Cluster, Sales Cluster, Concrete Transactions Cluster, and Physical Cluster) on the personality traits as measured by the 16 PF Questionnaire (Sizothymia- Affectothymia, Intelligence, Emotionality-Ego Strength, Submissiveness-Dominance, Desurgency-Surgency, Superego Strength, Threctia-Parmia, Alaxia-Protension, Praxernia-Autia, Artlessness-Shrewdness, Adequacy-Apprehension, Conservatism- Radicalism, Adherence-Self Sufficiency, Integration of Self Concept, and Ergic Tension).
