The use of finite intersection tests (FIT) to unify methods for simultaneous inference and to test orthogonal contrasts is discussed. Multiple comparison procedures that combine FIT with sequential hypothesis testing are illustrated, and a simulation strategy is presented to generate values needed for FIT methods. (SLD)

Conducted simulations to explore methods for comparing bivariate distributions corresponding to two independent groups, all of which are based on Tukey's "depth," a generalization of the notion of ranks to multivariate data. Discusses steps needed to control Type I error. (SLD)

Sampling theory for the intraclass reliability coefficient, a Spearman-Brown extrapolation of alpha to a single measurement for each examinee, is less recognized and less cited than that of coefficient alpha. Techniques for constructing confidence intervals and testing hypotheses for the intraclass coefficient are presented. (SLD)

This computer program computes the adjusted alpha level using the original Bonferroni procedure and four modified Bonferroni procedures. It is written in Statistical Analysis System (SAS) macro language. Input and output features are described. (SLD)

Proposes an extension of the propensity score adjustment method to the analysis of group differences on latent variable models. Uses multiple indicators-multiple causes (MIMIC) structural equation modeling to test hypotheses about treatment group differences. Discusses the role of factorial invariance as it relates to this approach. (SLD)

A method based on Spearman rank-order correlation coefficients was applied to the hypothesized ranks among correlations in Holland's hexagon of vocational interests. The procedure was easy to compute and apply and was amenable to comparing the fit in several matrices and to conducting meta-analysis. (SK)

In developing a theoretical framework for the field of ecological acoustics, Gaver (1993b) distinguished between the experience of musical listening (perceiving sounds) and everyday listening (perceiving sources of sounds). Within the everyday listening experience, Gaver (1993a) proposed that the frequency of an object results from, and therefore…

A didactic discussion of covariance structure modeling in longitudinal studies with missing data is presented. Use of the full-information maximum likelihood method is considered for model fitting, parameter estimation, and hypothesis testing purposes, particularly when interested in patterns of temporal change as well as its covariates and…

Deep dyslexia is an acquired reading disorder that involves the production of semantic errors and the inability to read aloud nonwords successfully. Several explanations for this reading impairment posit multiple loci of damage to account for the various error types produced in deep dyslexia. In contrast, the failure of inhibition hypothesis…

This article describes the students' academic progress in an online course of business statistics through interactive software assignments and diverse educational homework, which helps these students to build their own e-learning through basic competences; i.e. interpreting results and solving problems. Cross-tables were built for the categorical…

The purpose of this mixed methods study was to examine the impact that a teacher-guided library selection program had on overall reading scores and how this program may or may not promote reading improvement of fourth-grade students at a small suburban school in western New York. Forty fourth graders were used as the sample population, which was…

The purpose of this study was to investigate teacher and school psychologists' knowledge of Attention-Deficit/Hyperactivity Disorder (ADHD). One hundred thirty-two kindergarten through 12th-grade general education teachers, special education teachers, and school psychologists responded to a 24-item questionnaire concerning treatment and possible…

Inflated responsibility is ascribed a pivotal role in the pathogenesis of obsessive-compulsive disorder (OCD). The aim of the study was to assess interpersonal attitudes and behaviors contributing to enhanced responsibility in OCD. In particular, we tested the hypothesis that individuals diagnosed with OCD share stronger latent aggression toward…

The current study presented 1,933 adolescents from 13 schools with a scenario about a hypothetical peer's plan to "do something dangerous" at school and asked how likely they would be to respond with four different actions: intervene directly, tell a teacher or principal, discuss it with a friend but not an adult, and do nothing. High school…

To test the hypothesis that the etiology of reading difficulties may differ for males and females in more severely impaired samples, reading performance data from monozygotic (MZ), same-sex dizygotic (DZ[subscript ss]), and opposite-sex dizygotic (DZ[subscript os]) twin pairs were analyzed using a model-fitting implementation of the DeFries-Fulker…
