Krus, David J.; Wilkinson, Sue Marie – Educational and Psychological Measurement, 1986
Matrix differencing of data vectors is introduced as a method for computing test variance and is compared to traditional analysis of variance. Applications for computer assisted instruction, provided by supplemental computer software, are also described. (Author/GDC)

Krus, David J.; Stanley, Maureen A. – Educational and Psychological Measurement, 1985
The Attitudes toward Bilingual Education scale was shown to be valid with respect to its ability to discriminate between proponents of bilingual education and a general population. (The 23-item scale is included). (Author/GDC)
Descriptors: Attitude Measures, Bilingual Education Programs, Elementary Secondary Education, Family Attitudes

Krus, David J.; Liang, Kun-Hsia T. – Educational and Psychological Measurement, 1984
An algorithm for estimation of means and standard deviations or raw scores underlying table values of standard test scores is presented. An application of a computer program, operationalizing the suggested algorithm, is discussed within the framework of a comparison of estimated and known table values for sample Minnesota Multiphasic Personality…

Helmstadter, G. C.; Krus, David J. – Educational and Psychological Measurement, 1982
The Berkeley student evaluation questionnaire by Hildebrand, Wilson, and Dienst was modified to reflect the Whitely-Doyle factorial structure of implicit theories students hold about teaching characteristics of their instructors. Student ratings appear to be valid indicators of teaching competency, admissable as evidence to be used for faculty…

Krus, David J.; Krus, Patricia H. – Educational and Psychological Measurement, 1977
Described is a Fortran computer program for an alternative algorithm for Thurstone's pair comparisons method. This algorithm provides an improved capacity for handling indeterminate proportions of one and zero as well as untruncated estimates of population scale values. (Author/JKS)

Krus, Patricia H.; Krus, David J. – Educational and Psychological Measurement, 1977
A Fortran program is presented that administers, scores, and interprets the Interpersonal Check List. Included in the program are test items, protocols for administration and scoring, printing of individually-tailored interpretation of results, and a pictorial plot describing the characteristic interpersonal behavior in terms of two orthogonal…

Krus, David J.; Krus, Patricia H. – Educational and Psychological Measurement, 1977
A description of a Fortran program for linear and area transformations of test scores with optional generation of symmetric tables of areas under the standard normal curve is presented. Also included is a historic note on the origin of McCall's T Scale. (Author/JKS)
Descriptors: Computer Programs, Equated Scores, Measurement Techniques
Peer reviewed Peer reviewed
Krus, David J.; And Others – Educational and Psychological Measurement, 1976
Description of a computer program performing rotated canonical variate analysis was presented. The program is compatible with the IBM Scientific Subroutines Package. Examples of rotated and unrotated solutions of a sample problem were given, together with their interpretations illustrating the advantages of the rotated solution. (Author)

Krus, David J.; Helmstadter, Gerald C. – Educational and Psychological Measurement, 1987
The Spearman-Brown (S-B) formula for correction of the split-half coefficient of reliability is discussed as a conceptual precursor of modern formulations of internal-consistency reliability. Derived from the principal components of the product moment coefficient, an alternative S-B formulation facilitates an understanding of internal…

Krus, David J.; Lu, Mei-Yan – Educational and Psychological Measurement, 1987
The viability of the FORTRAN computer language and its relationship to other languages (such as PASCAL) were discussed. A library of C language and assembly language FORTRAN-callable subroutines, developed for the use of behavioral science researchers, was introduced. (Author/GDC)

Krus, David J.; Kodimer, Dennis – Educational and Psychological Measurement, 1987
Handlers for interfacing the ScanTron and 2700 Optical Mark Readers with the IBM AT/XT/PC and Tandy 2000/1000/3000 iAPX 88/186/286 based computers were described. Differences between programing an RS232C serial port using BIOS interrupts and directly addressing the Motorola 8550 ART microprocessor were discussed. (Author/LMO)

Krus, David J.; Helmstadter, Gerald C. – Educational and Psychological Measurement, 1993
Negative coefficients of reliability, sometimes returned by the standard formula for estimation of the internal-consistency reliability, are neither theoretically nor numerically correct. Alternative strategies for test development in this special case are suggested. (Author)
