Recent and ongoing research has demonstrated the alarming likelihood of children from low-income homes and from ethnic minorities to read at much lower reading levels than their peers. Additionally, reading ability is related to the earliest of emergent literacy skills, which can be measured in young children before they enter formal schooling.…

This research investigates the incidence and wage effects of overskilling for vocational education and training (VET) graduates in Australia between 2001 and 2006. Overskilling is defined as the extent to which workers are able to use their skills and abilities in their current job. The authors compare overskilling with other measures of skill…

This study sought to compare the performance of students in the College Board Advanced Placement Program® (AP®) compared to non-AP students on a number of college outcome measures. Ten individual AP Exams were examined in this study of students in four entering classes (1998-2001) at the University of Texas at Austin. The four main groups of…

This study was grounded in the belief systems and physical activity literature and investigated preservice teachers' belief systems toward curricular outcomes for physical education programs. Preservice teachers (N = 486; men = 62%, women = 38%) from 18 U.S. colleges/universities shared their beliefs about curricular outcomes. Preservice teachers…

The Trends in International Mathematics and Science Study (TIMSS) Video Study explored instructional practices in the United States (US) in comparison with other countries that ranked higher on the 1999 TIMSS assessment, and revealed that 8th grade science teachers in the US emphasize activities over content during lessons (Roth et al.…

The purpose of this study was to evaluate the common assumption that teachers of color (TOC) are more culturally competent than White teachers by assessing physical education teachers' cultural competency. A secondary purpose was to ascertain the possible differences in cultural competence levels of White teachers in diverse school settings versus…

This paper briefly explains the logic underlying the basic calculations employed in canonical correlation analysis. A small hypothetical data set is employed to illustrate that canonical correlation analysis subsumes both univariate and multivariate parametric methods. Several real data sets are employed to illustrate other themes. Three common…

This paper describes two BASIC computer programs that calculate Hotelling's T-square either for one sample or for two samples. Output of the progams includes the Mahalanobis distance D-square, the F ratio associated with T-square, and its probability level. (Author)

Several methods for quantifying categorical multivariate data (including multiple correspondence analysis and optimal scaling) are discussed and shown to be equivalent. The method can be applied by variable matrix with categorical variables, by item matrix of multiple-choice data, or by a multi-way contingency table. (NSF)

Orthogonal rotation of canonical variates is shown to preserve the major properties of the canonical solution and may increase its interpretability. Empirical illustrations are given. (Author/HG)

This paper explains the theory and methodology behind the use of variable deletion in canonical correlational analysis (CCA). Both the Capraro and Capraro (2002) and the Cantrell (1997) data tables are evaluated and explained in order to clarify strategies utilized. Understanding of variable deletion strategies and their proper usages in a CCA…

Because multivariate statistics are increasing in popularity with social science researchers, the challenge of detecting multivariate outliers warrants attention. Outliers are defined as cases which, in regression analyses, generally lie more than three standard deviations from Yhat and therefore distort statistics. There are, however, some…

This paper reviews graphical and nongraphical procedures for evaluating multivariate normality by guiding the reader through univariate and bivariate procedures that are necessary, but insufficient, indications of a multivariate normal distribution. A data set using three dependent variables for two groups provided by D. George and P. Mallery…

This paper reviews the concept of experimentwise Type I error. While "testwise" alpha refers to the probability of making a Type I error for a single hypothesis test, "experimentwise" error refers to the probability of having made a Type I error anywhere within the study. Experimentwise error concerns are the basis for two…

Criteria for assessing variable performance in multivariate analysis of variance (MANOVA) are considered, examining criteria suggested by Huberty and Wisenbaker (1992), the contribution to linear discriminant function scores and the contribution to grouping variable effects. It is proposed that the two criteria be amalgamated as the contribution…
