Derived Basic Ability Factors: A Factor Analysis Replication Study.
Lee, Mickey, M.; Lee, Lynda Newby
The purpose of this study was to replicate the study conducted by Potter, Sagraves, and McDonald to determine whether their recommended analysis could separate criterion variables into similar factors that were stable from year to year and from school to school. The replication samples consisted of all students attending Louisiana State University School of Dentistry during the 1979-83 academic years. The sample included 76 freshman, 88 sophomores, and 92 juniors (total N-256). The variables assessed consisted of all courses taken during their freshman, sophomore, and junior years. The courses included lecture, preclinical, and clinical courses. The method chosen to validate the basic ability groupings was factor analysis, using principal component analysis and rotating the obtained factors through verimax rotation analysis. This was accomplished using the Statistical Package for the Social Sciences program, Factor Analysis. A criterion of .50 was used to replicate the chosen factor loading in the study. The results, unlike those of Potter et al., failed to separate criterion variables into similar basic ability factors. For four freshman classes, no consistent pattern appeared. For three sophomore classes and two junior classes, only suggestions and possible patterns were present. (Author)
