Some years ago, B. Efron and his colleagues developed bootstrap resampling methods as a way of estimating the degree to which statistical results will replicate across variations in sample. A basic problem in the multivariate use of bootstrap procedures involves the requirement that the results across resamplings must be rotated to best fit in a…

In previous research, no relationship was found between test factor structure and test hierarchical structure. This study found some correspondence between test factor structure and test inter-item dependency structure, as measured by a log-linear model. There was an inconsistency, however, which warrants further study: more significant two-item…

Through a review of the literature, this paper explores the viability of the rotation of canonical correlation analysis results. The similarities and dissimilarities between factor analysis and canonical correlation analysis are examined. The logic supporting a preference for the rotation of structure coefficients as opposed to function…

Because ignoring the missing data in an evaluation may lead to results that are questionable, this study investigated the effects of use of four missing data handling techniques on a survey instrument. A questionnaire containing 35 5-point Likert-style questions was completed by 384 respondents. Of these, 166 (43%) questionnaires contained 1 or…

Few methods have been tried and used to graphically represent more than two variables. This poster session showed a new method for representing three continuous variables on a single scatterplot using the THREEDE computer program. Two variables are represented as a normal bivariate distribution. The third variable is represented by a symbol, e.g.…

The Wechsler Intelligence Scale for Children - Revised (WISC-R) and the Wechsler Intelligence Scale for Children (WISC) were administered in counter-balanced order to 81 children aged 7-12 in New South Wales, Australia. Canonical correlation analysis showed the total redundancy values of WISC-R given WISC and WISC given WISC-R to be .58 and .61…

The effect of gender and grade point average (GPA) on emotional intelligence (EQ) was studied using the Emotional Intelligence Inventory. The inventory was completed by 138 college students, and data were analyzed using a multivariate factorial model with three factors of EQ as dependent variables (compassion, self-awareness, and attunement) and…

Efforts to study the fidelity of translation of attitudinal scales into foreign languages have faltered due to the lack of powerful statistical tests to assess such transformations. This study uses a maximum likelihood factor analysis procedure to compare multivariate factor structures across subpopulations. The results showed that inconsistent…

Underlying structure of the Basic Achievement Skills Individual Screener (BASIS) and the Kaufman Test of Educational Achievement (K-TEA) were investigated using canonical correlation. Both are individually administered placement and screening instruments currently in use in many school systems that measure achievement in mathematics, reading, and…

A study was conducted to examine the validity of the Learning-Thinking Style Inventory (LTSI) and to investigate the learning and thinking styles of college students in relation to their major and academic performance. Generated out of the framework of personality model and information processing theory, the 49-item LTSI embraces a broad spectrum…

In an attempt to determine the subscale structures most useful for identifying adolescents with social skill deficits, this study investigated the factor structure of the Teenage Inventory of Social Skills (TISS) and its relationship to two measures of adolescent social competence. Two measures were completed by 1,142 ninth-grade students (577…
