Abstract
This study investigated the measurable statistical differences in inventoried interests among three groups of engineers at Purdue University. Multiple discriminant function analysis was used to investigate the interest patterns of 229 Purdue freshman engineers who were administered the Strong Vocational Interest Blank for Men (SVIB) as freshmen in 1935 and again in 1966. A third group consisted of 210 Purdue freshmen who completed the SVIB in 1966 and had persisted in engineering for two years. Statistically significant differences existed for career counseling with prospective engineers. Results from this study supported other researchers' findings that the Engineer scale on the SVIB is no longer an adequate measure of engineers' interests.
