Describes investigation of casual attribution categories of faith, logic, and power along with personal responsibility as components of attitudes toward disability. Multiple regression analyses using rank ordering data and correspondence analysis coordinates yielded high coefficients for all categories indicating concepts implicit in categories…

Describes how multilevel logistic regression can be used to assess the consistency of an individuals' response pattern with an item response theory measurement model. Outlines the advantages of this proposed modeling approach over traditional techniques, specifically that the multilevel modeling approach allows explanatory variables to be entered…

Reports the results of a study of final discharge outcomes for an exit cohort of 2,653 foster youths in California who were 17 years of age or older. A youth's number of placements in foster care, time spent in care, and the type of placement in which the adolescent last resided were all found to be related to discharge status. (JPS)

Discusses the optimal level of randomization, the optimal allocation of units, and the budget for obtaining a certain power on a test of no treatment effect for populations with two or three levels of nesting and continuous outcomes. Focuses on the estimator of the regression coefficient associated with the treatment condition. (SLD)

Conducted a regression analysis to assess the contributions of passage and no-passage factors to item variance on the Scholastic Aptitude Test reading comprehension task. Results show that no-passage factors play a larger role than do passage factors, accounting for as much as three-fourths of systematic variance in item difficulty and more than…

Used logistic regression to model the observation-to-variable ratio required for the standard error scree procedure to identify the number of factors in simulated data correctly. Results demonstrate the ability of logistic regression to simplify summarizing and reporting findings from simulation studies that involve a large number of conditions.…

The coding of time in growth curve models has important implications for the interpretation of the resulting model that are sometimes not transparent. The authors develop a general framework that includes predictors of growth curve components to illustrate how parameter estimates and their standard errors are exactly determined as a function of…

An activity that revolves around a data set that is created by students is described. The activity is divided into two parts that is exploration of simple linear regression and exploration of quadratic regression and cubic regression.

To assess the relationship between different facets of conservative ideology and ambivalent sexism, 246 residents of two towns in southern Michigan completed a social dominance orientation scale (SDO), a right-wing authoritarianism scale (RWA), a Protestant work ethic scale (PWE), and the Glick and Fiske (1996) Ambivalent Sexism Inventory via a…

With the current concern over the growing need for more engineers, there is an immediate need to improve freshman engineering retention. A working model for freshman engineering retention is needed. This paper proposes such a model based on Tinto's Interactionalist Theory. Emphasis in this model is placed on pre-college characteristics as…

This paper examines several ways in which teaching effectiveness and student learning in an undergraduate Business Statistics course can be enhanced. First, we review some key concepts in Business Statistics that are often challenging to teach and show how using real data sets assist students in developing deeper understanding of the concepts.…

Using data collected from surveys completed by grandparents for their grandchildren (N = 72), this quantitative study examines the effects grandparent primary caregivers have on the reading achievement of their African American grandchildren. The study sought to answer the following question: How do the six types of parental involvement (Epstein,…

This non-experimental, correlational study looked at the relationship between bureaucratic structures in middle and high schools in bringing about change in individual teacher classroom instructional practices through the centralized directive of membership in a professional learning community. Using a continuum of bureaucratic structure, from…

This study investigated relationships among measures of perfectionism, academic self-concept, and academic achievement in fourth and fifth grade children from selective primary schools in Hong Kong where admission involves strict assessment of students' aptitude and potential. Based on their overall academic performance 331 students were…

As the U.S. Latino population continues to diversify, it is necessary to understand their experiences of minority status and its implications for well-being. The present cross-sectional study investigates early adolescents' perceptions of public regard for their ethnic group and perceptions of the extent to which opportunity is differentiated by…
