The writers of this paper draw on their own research efforts and an extensive review of the literature related to prediction of delinquency (and the related factors of personal and social adjustment, health problems, welfare status, and academic underachievement) to point out a number of deficiencies and difficulties encountered in research…

This report compares maximum linear prediction, maximum total correct classifications for a group, and maximum probability of correct classification for an individual as objective criteria for univariate grading scales. Since the goals of valid prediction and valid classification lead to conflicting criteria, it is possible that a compromise…

The purpose of this research is to evaluate the effectiveness of the area (homogeneous) scales of the Navy Vocational Interest Inventory (NVII) as predictors of Class "A" school achievement and as measures of rating differentiation by comparing specific occupational scales with more general interest measures--the NVII area scales. The…

Increasing demands for accurate forecasts in such areas as student enrollment, energy expenditures, and facility capacity are placing new demands on the institutional researcher. A variety of forecasting models and methods are available, all to be used with caution in long-range forecasting. (Author/MSE)

The statistical and institutional influences on the prediction of first-year college grades were examined using data from College Board validity studies and the College Handbook. The criterion was the size of the multiple correlation between academic predictors and first-year college grades. (Author/MLW)

Vacuum forming of thermoplastic was the manipulation tested, by various demonstration methods. (GB)

Presents and discusses the results of a study undertaken at Washington State University to determine whether different subgroups of the library collection had different loss and misshelving rates and, if so, whether the worst problems could be predicted from circulation data. Two tables present the data from the study. (Author/JL)

The predictive analysis approach to adaptive testing originated in the idea of statistical predictive analysis suggested by J. Aitchison and I.R. Dunsmore (1975). The adaptive testing model proposed is based on parameter-free predictive distribution. Aitchison and Dunsmore define statistical prediction analysis as the use of data obtained from an…

Pre-selection criteria were developed to obtain a profile of student nurses who would compute a community college nursing program, and student nurses who would leave the program prior to completion. The battery consisted of tests and questionnaires based upon cognitive, personality/attitude, vocational preference, and socioeconomic status domains.…

This study demonstrates and discusses a new procedure for performing item analysis which utilizes multiple discriminant analysis to establish efficiently and effectively an index of item validity. Application of this statistical technique to data derived from an attitude survey of three groups of students enrolled in technical training courses…

Twenty-nine community characteristics were studied to determine which were statistically most useful as predictors of per-pupil Federal aid to the 169 school districts of Connecticut. Three regression models were developed using community traits as predictors of Federal aid allocations. Cross-validation of regression models to predict future…

A statistical study of 90 students entering the Medical College of Virginia/Virginia Commonwealth University School of Pharmacy in 1974 indicates that PCAT scores are clearly superior predictors over these scores: SAT-Verbal and -Math; college quality point average (QPA); Otis Quick-Scoring Mental Ability Test; and pharmacy course grade. (LBH)

The number of regression studies being employed in sex discrimination cases is increasing. The need for caution in the case of multiple regression must be emphasized. Statistical concerns in sex discrimination cases are highlighted. (MLW)

Thorndike's Stanford-Binet data suggest that from 1932 to 1971-72 preschool children enjoyed greater IQ gains than older children, possibly due to the rise of television. Additional analysis indicated that gains were either due to sampling error or totally antedated 1947. Gains of 12 IQ points were found for Americans. (Author/EGS)

In distinguishing the characteristics of message systems, it was found that middle-class messages were generally more difficult to predict while working-class systems were more predictable and stereotyped. (Author/MB)
