Three different computational procedures for equating two forms of a test were applied to a pair of mathematics tests to compare the results of the three procedures. The tests that were being equated were two forms of the SRA Mastery Mathematics Tests. The common, linking test used for equating was the Comprehensive Tests of Basic Skills, Form S,…

Statistical and econometric techniques of correcting for supervisor bias in models of individual performance appraisal were developed, using a variant of the classical linear regression model. Location bias occurs when individual performance is systematically overestimated or underestimated, while scale bias results when raters either exaggerate…

Large disparities between blacks and whites in both earnings and income have persisted during the period since World War II. In this paper estimates are presented of the contribution of labor market discrimination to the earnings differential. Lower and upper bounds on this contribution are set. Also measured is the extent to which labor market…

The ratings of 43 third-year medical students were used to investigate a method of computing the reliability of ratings. The students were evaluated on a four-point rating scale along seven dimensions of clinical ability: diagnostic ability; motivation; sense of responsibility; oral-verbal ability; effectiveness with patients; ability to take a…

Information about tax assistance to public universities and colleges for 1979-1980 is provided. The report details state tax-fund appropriations alphabetically by state for operating expenses of higher education. Among findings were that the 50 states appropriated more than $19 billion for annual operating expenses in fiscal year 1979-1980, that…

This annual report consists of two major sections--the system staff and programs of the state's ten library systems, and the summary budget analysis. Information provided for each of the ten systems includes the address, telephone number, name of system coordinator of the interlibrary loan office and a directory of staff members; names and…

Using a multidimensional scaling procedure, this study examined the fit of Holland's RIASEC hexagon model to the internal relationships among the Strong-Campbell Interest Inventory (SCII) General Occupational Theme scales. SCII intercorrelation matrices for both sexes as reported in the SCII Manual were submitted, separately for each sex, to…

Two methods of item selection were used to select sets of 40 items from a 50-item verbal analogies test, and the resulting item sets were compared for relative efficiency. The BICAL program was used to select the 40 items having the best mean square fit to the one parameter logistic (Rasch) model. The LOGIST program was used to select the 40 items…

Using 1970 Federal Census data, this paper analyzes selected characteristics of the black population in Alabama, focusing on the following categories: (1) blacks in Alabama counties; (2) urban and rural blacks; and (3) blacks in Alabama by sex and age. Special emphasis is placed on producing and interpreting data by which postsecondary education…

This paper describes a model for the systematic design, development, and validation of alternative instructional modules, by incorporating the basic concepts underlying Aptitude Treatment Interaction (ATI) analyses. The proposed working model is based on the premise that the ATI concept is best applied, not in isolation, but as an integral part of…

The purpose of this analysis is to provide an estimate of the mean correlation of home environment measures with learning measures across studies and to indicate sample and study characteristics associated with different magnitudes of correlation. University of Chicago studies of behavioral processes and British investigations of parental…

The use of various physiological tests and measurements accurately predicts the performance ratings of female athletes. A study involving 180 female intercollegiate volleyball players, 142 female intercollegiate basketball players, and 115 female college-age nonathletes yielded a set of statistical differentials concerning arm length, lean weight…

Alternative techniques for analyzing student outcomes were investigated. Two traditional statistical methods (one-way analysis of variance and two-way analysis of variance) were compared with an innovative input-output analysis. The input-output analysis is a two-step analysis consisting of a regression analysis to determine the relationships…

TWO CHEMISTRY GRADUATE STUDENTS WERE TRAINED IN INDEXING TECHNICAL DOCUMENTS THROUGH AN ESTABLISHED TRAINING PROGRAM WHICH WAS MODIFIED FOR IMPROVEMENT. A STUDY OF INTRA- AND INTERINDEXER CONSISTENCY WAS MADE BY SUBJECTING A GROUP OF TECHNICAL DOCUMENTS TO INDEPENDENT INDEXING BY VARIOUS INDIVIDUALS AND TWO OF THE SAME INDIVIDUALS ONE YEAR LATER.…

The objectives of this research were to investigage (1) the feasibility of an index simulator, and (2) the use of a sequential analysis model for the automatic classification of documents. Index simulation was studied in general for various types of indexes, and in depth for the simulation of an inverted coordinate index to a document collection…
