Statistics Attitude Survey (SAS) scores were significantly related to: (1) cognitive variables such as basic mathematics skills, statistics preknowledge, course grades; and (2) noncognitive factors such as sex, desire to take a course, previous math courses, course status, calculator attitudes, and course and instructor evaluations. (Author/PN)

A 10 item Attitudes Toward Computers instrument was developed to measure the attitudes of students toward the use of computers. A factorial validity study revealed one identifiable factor dimension entitled General Attitude Toward Computers with an estimated alpha internal consistency reliability of .87. (Author/PN)

The psychometric characteristics of the revised UCLA Loneliness Scale in Iranian groups correlated significantly with measures of other conceptually-related variables such as depression, anxiety, and neuroticism. Factorial structure supported the multidimensionality of the scale. (Author/PN)

The concurrent and postdictive validity of two newly-devised tests of contrasting hemispheric function (Test of Right Hemisphere Ability, Test of Left Hemisphere Ability) was investigated relative to scores earned on the reading and mathematics portions of the Comprehensive Tests of Basic Skills. (Author/PN)

Selected structure-of-intellect factor measures were compared with subtests of the Florida State-Wide Twelfth Grade Test in predicting physics achievement. Multiple correlation coefficients were approximately the same when both sets were used together to predict physics achievement. (Author/PN)

If the null hypothesis of a one-sample test of multivariate means is rejected, the dimension of the line joining the population centroid and the hypothesized centroid can be interpreted with a linear function, using a discriminant function and the correlation of each dependent variable with a discriminant score.

The generalizability of student evaluations of college instruction is analyzed and generalizability theory data collected in a common design is applied. Results suggest that use of student evaluations of teacher effectiveness may lead to decisions based upon undependable data. (Author/GK)

This study was concerned with selecting a measure of scorer agreement for use with the National Assessment of Educational Progress. The simple percent of agreement and Cohen's kappa were compared. It was concluded that Cohen's kappa does not add sufficient information to make its calculation worthwhile. (Author/BW)

Presented is evidence bearing on the construct validity of the Estimate of Self-Competence (ESC) Scale, which was designed to measure generalized expectancy of task success. The results of correlational analyses of relationships between the ESC, expectancies of successful performance, and other measures are reported. (Author/AL)

This paper examines the properties of the Item Efficiency Index proposed by Neill and Jackson (1976; EJ 137 077) for minimum redundancy item analysis. (Author/BW)

The magnitude of statistical bias for the phi-coefficient was investigated, using computer simulated examinations in which all the students had equal knowledge. Several modifications of phi were tested, but when applied to real examinations, none succeeded in improving its reproducibility when items are re-used on equivalent student groups.…

Many researchers draw the conclusion that one independent variable has more impact than another without testing the null hypothesis that their impact is equal. This paper presents and recommends a technique for testing the relative magnitude of effects, rather than basing conclusions solely on descriptive statistics. (Author/BW)

The Home Observation for Measurement of the Environment (HOME) underwent a generalizability study examining the consistency and stability of scores. Canonical correlation and principal components factor analysis indicated that the organization of environment changes over the first two years of life, and the amount--not type--of stimulation is…

In many personality and interest inventories, a score profile, rather than a single score, is attributed to each subject. Six applicable criteria are suggested for use in examining the adequacy of items in such inventories. These criteria relate to the items' response distributions, internal consistency, and discriminative value. (Author/BW)

The perfunctory use of factor scores in conjunction with regression analysis is inappropriate for many purposes. It is suggested that factoring methods are most suitable for independent variable sets when some consideration has been given to the nature of the domain, which is implied by the predictors.
