In this report, the author suggests changes in the treatment of overhead costs by hypothesizing that "the effectiveness of standard costing in planning and controlling overhead costs can be increased through the use of probability theory and associated statistical techniques." To test the hypothesis, the author (1) presents an overview of the…

This report examines existing mathematical methods that have been utilized to develop educational enrollment estimates and analyzes the applicability of these methods in the community college setting. Models surveyed are based on (1) extrapolation--by either survival cohort or cohort-regression, (2) structural flow, and (3) Markov-type procedures.…

This study utilized linear multiple regression analysis with dummy variables to isolate one component of an educational accountability system, the contribution of the individual teacher to student achievement. Independent variables consisted of measures of each student's past academic record, the size of the class and a dummy variable to represent…

This paper discusses the use of contrast coefficients in multiple linear regression models, and shows how they can provide for a logical method of analysis in both the analysis of variance and the analysis of covariance. (CK)

The importance of college image on student enrollment choices is discussed and a model is described which, using various student background variables as independent variables and college choice as the dependent variable, tries to assess the factors which determine college choice. (SE)

Part 1 of a two-part article describing a study that attempts to identify determinants of change in teacher salaries and examines both school district contextual factors and school district negotiations characteristics in terms of final contracts negotiated in New York during the 1971-72 school year. (JG)

This study, based on a survey of rural families in several provinces in Indonesia, is an attempt to search for variables, and combinations of variables, that predict the actual utilization of schooling by individual families. Suggests these useful predictors: family characteristics, family economic status, family orientation toward education.…

Socioeconomic differences were controlled for an examination of longitudinal data on established critical factors in career salience of female college graduates. Details about mother's employment history, respondent's recollection of the attitudes of family members concerning that employment, and indicators of daughter's sex role ideology were…

The construction and interpretation of confidence intervals for the prediction of new cases in multiple regression analysis is explained. An example is provided. (JKS)

Kaufman and Sweet's article on the regression analysis of unbalanced factorial designs (EJ 111 767) is reviewed. A number of errors are noted, and relevant literature is cited. (GDC)

The influence of school building age on the academic achievement of pupils in the fourth, eight, and eleventh grades is examined while controlling the variance due to selected socioeconomic factors. (Author/MLF)

Two measures of "breadth" and three measures of "depth" were derived, based on special administration and scoring of the Wechsler Similarities subscale. Factor analyses indicated that breadth and depth can be distinguished statistically, and multiple regression analyses revealed that the derived measures contributed to improved…

Discusses the use and interpretation of multiple regression analysis with computer programs and presents a flow chart of the process. A general explanation of the flow chart is provided, followed by an example showing the development of a linear equation which could be used in estimating manufacturing overhead cost. (Author/LRW)

Eighty-one university students were given a battery of reaction time tests and a group test of intelligence which yielded timed and untimed scores. Multiple regression analyses indicated that speed of information-processing was an equally good predictor of timed and untimed intelligence test performance. (Author/LMO)

A study to compare cognitive functioning in acutely and chronically sleep-deprived house officers is described. A multivariate analysis of variance revealed significant deficits in primary mental tasks involving basic rote memory, language, and numeric skills. (Author/MLW)
