An alternative way of studying group differences is proposed based on ordering analysis using item hierarchies as a basis of comparison between two groups. Subjects were sets of twins in elementary school. Results showed that blacks and whites and males and females had similar item hierarchies for complex items. (Author/LMO)

This paper reports on the application of Yukl's Management Behavior Survey in 47 elementary schools. Three problems with the instrument are discussed: (1) lack of response; (2) interrater disagreement; and (3) ceiling effects. The dimensionality of the measure is evaluated through factor analysis.

This paper points out the logical, theoretical, and statistical problems associated with the computation of the "pooled-within" correlation coefficient in partially segregated educational systems. (Author/LMO)

An empirical method (PRESS) for examining and contrasting the cross-validated prediction accuracies of some popular algorithms for weighting predictor variables was advanced and examined. The sample specific PRESS method was suggested as most appropriate when selecting among several alternative weighting algorithms to achieve maximum…

Three exact probability tests, counterparts of t tests for single sample, independent samples, and dependent samples, are described for data obtained from ratings on "m" scales by a single rater or on a single scale by "n" raters. (LMO)

Correct simple formulas are provided for the value of phi needed to use the commonly available Pearson and Hartley power charts in determining the power of hypothesis tests involving simple degree-of-freedom comparisons in the fixed effects analysis of variance. (LMO)

The Survey of Reading Attitudes-Primary Level was administered orally to 269 first-grade, 240 second-grade, and 236 third-grade students. The responses were factored separately by grade using a principal factor method with varimax rotation. The results provided evidence for the multidimensionality of primary students' reading attitudes. (LMO)

Each of 434 West German and 446 American high school teachers nominated one student as highly gifted. All teachers completed a questionnaire in which they rated their nominees on 83 characteristics. The intercorrelations of the items were factor analyzed to yield seven German and five American factors. (LMO)

This paper reports a Monte Carlo study of differences induced by different analysis choices over selected types of aptitude treatment interaction (ATI) data (nine combinations of three sample sizes and three population parameter effect sizes). Generally, ANOVA methods tended to overestimate smaller effect sizes and to underestimate larger effect…

The runs test for random sequences of responding is proposed for application in long inventories with dichotomous items as an index of sterotyped responding. This index is useful for detecting whether the client shifts between response alternatives more or less frequently than would be expected by chance. (LMO)

This paper evaluates four selection procedures for hiring school principals. These procedures (interviews, assessment center, selected assessment center exercises, and paper and pencil inventories) were compared in terms of validity, processing costs, and dollar gain expected from implementation. The selected assessment center exercises were found…

The issue addressed by this study was whether the Jesness Inventory Classification System as revised for hand-scoring can provide useful information about the personality and behavior of nonoffenders. Data on the System's construct validity showed that youths of the nine subtypes differed on many background, personality, attitude, and behavioral…

Construction and validation of the Personality Adjective Inventory, a new test of personality based on Murray's need-press theory and following the lead of the Personality Research Form is described. The inventory shows excellent psychometric properties across several measures of reliability, stability, and validity. (Author/LMO)

The 72-item Erikson Psychosocial Stage Inventory (EPSI) was factor analyzed for a group of 534 university freshmen and sophomore students. Seven factors emerged, which were labeled Initiative, Industry, Identity, Friendship, Dating, Goal Clarity, and Self-Confidence. Item's representing Erikson's factors, Trust and Autonomy, were dispersed across…

This study evaluated the degree to which 102 undergraduate participants objected to questions on the Minnesota Multiphasic Personality Inventory (MMPI) which referred to sex, religion, bladder and bowel functions, family relationships, and unusual thinking in comparision to degree of objection to length of the MMPI and repetition of questions.…
