Path analysis was used to test the T into model of college dropouts using a sample drawn from the National Longitudinal Study of the High School Class of 1972. Findings support the notion that commitment to the goal of college completion has the strongest effect on persistence. (Author/GK)

An extension of the methods of path analysis to include studies of categorical data was described and exemplified in a causal study of college dropouts. The usual models and methods of causal (path) analysis were designed for the study of quantitative variables and are not appropriate when the variables under investigation are categorical.…

Characteristics and attendance patterns of persisters and dropouts from college and vocational/technical schools were studied, and a model of the persistence process was tested using data from the National Longitudinal Study (NLS), which surveyed high school seniors in 1972, with followup surveys in 1973 and 1974. Student persistence was defined…

Data from the National Longitudinal Study of the High School Class of 1972 (NLS) including the 1976 follow-up were used to examine the effects of interrupting or delaying school attendance on the eventual educational attainment of white male students. Background variables include socioeconomic and other family characteristics. Achievement test…

Since the mean score for a sample composed of several subgroups can be viewed as the sum of the mean of each subgroup weighted by the proportional size of the subgroup, then the mean change in a time period--in this case, from 1972 to 1980--is the sum of the differences between the means for each subgroup, with each mean weighted by its…
