College enrollment will be relatively stable over the next four years according to new projections by the U.S. Department of Education. (MLW)

Sources of error in body composition assessment by laboratory and field methods can be found in hydrostatic weighing, residual air volume, skinfolds, and circumferences. Statistical analysis can and should be used in the measurement of body composition. (CJ)

For much of the twentieth century, Markov theory and Markov processes have been widely accepted as valid ways to view statistical variables and parameters. In the complex realm of online searching, where researchers are always seeking the route to the best search strategies and the most powerful query terms and sequences, Markov process analysis…

To determine how well certain factors would predict academic achievement, 97 freshmen and 48 sophomores, all full-time 1968-69 students, were tested. The factors were (1) high school GPA, (2) American College Testing (ACT) English test, (3) ACT math portion, (4) ACT social studies portion, (5) ACT natural science portion. The criterion of…

Double-entry expectancy tables are used to make admissions, guidance, or employment decisions based on two predictors. Examples of their use in showing relationships between high school and college performance are explained. The advantages of double-entry expectacy tables given are: (1) relative simplicity of preparation requiring no formal…

The common approach to studies of predictive bias is analyzed within the context of a conceptual model in which predictors and criterion measures are viewed as fallible indicators of idealized qualifications. (Author/PN)

A method is developed for testing a priori multiple regression models. The method allows one to specify in advance as many unstandardized or standardized coefficients as one wants to and allows the remaining slopes to be free to vary. (Author/PN)

Four commonly employed procedures were repeatedly applied to computer-simulated samples to provide comparative data pertaining to two questions: (a) which procedure can be expected to produce and equation that yields the most accurate predictions for the population, and (b) which procedure is most likely to identify the optimal set of independent…

The EAS though less time consuming is shown to cover major psychological constructs of the ATGSB, and to offer a measure of the perceptual speed factor that was hypothesized to be related to success in computer-oriented and other data-analysis requirements in graduate business a schools. (Author/ES)

Suggests ways for using data from championship tennis as a means for exploring probabilistic models, especially binomial probability. Examples include the probability of winning a service point and the probability of winning a service game using data from tables and graphs. (AIM)

This paper describes a procedure for smoothing the proportions of a double-entry expectancy table which might be used in higher education admissions advising or other functions. The product of the smoothing procedure is a nomograph, a medium for displaying expectancies which provides pairs of individual values for two predictor variables rather…

The research reported contrasted the preregistration characteristics of graduates and non-graduates from the Special Educational Opportunities Program at the University of Illinois at Urbana-Champaign; 62 graduates and 433 non-graduates were included in the study sample. (Author/JM)

The merits of double exponential smoothing are discussed relative to other types of pattern-based enrollment forecasting methods. The difficulties associated with selecting an appropriate weight factor are discussed, and their potential effects on prediction results are illustrated. Two methods for objectively selecting the "best" weight…

THE PREDICTIVE SKILLS OF CLINICAL JUDGES WERE TESTED TO DETERMINE (1) IF VALIDATION EXPERIENCE AFFECTS THE ACCURACY OF CLINICAL JUDGMENT AND (2) IF THE CLINICAL JUDGE KNOWS WHEN TO DEVIATE FROM STATISTICAL PREDICTIONS. EIGHTEEN COUNSELORS WHO HAD PARTICIPATED IN A PREVIOUS INVESTIGATION OF PREDICTIVE SKILLS TOOK PART IN THE EXPERIMENT. ALL…
