Background: Youth programs often rely on self-reported data without clear evidence as to the accuracy of these reports. Although the validity of self-reporting has been confirmed among some high school and college age students, one area that is absent from extant literature is a serious investigation among younger children. Moreover, there is…

Speech samples of 79 dysarthric patients were judged for voice quality, articulation, nasality, and prosody as well as overall intelligibility. Application of a multiple regression model found that intelligibility can be expressed as a linear combination of weighted perceptual dimensions with articulation as the strongest contributor to…

This paper encourages the use of multiple logistic analysis in early intervention research, to assess the degree of association of multiple factors (such as subject or situational characteristics) with a dichotomous outcome (such as benefitting or not benefitting from an intervention) and to estimate the probability of each outcome. (JDD)

This study used multiple regression analysis to relate computer user satisfaction to communication monitor (CM) variables. Results indicate the variables of user expectations, manufacturers, and vendors are most significant in affecting overall satisfaction, whereas number of systems represented and not using communication monitors have least…

The number of regression studies being employed in sex discrimination cases is increasing. The need for caution in the case of multiple regression must be emphasized. Statistical concerns in sex discrimination cases are highlighted. (MLW)

This paper examines the use of statistical evidence, specifically regression analysis, in employment discrimination cases on college and university cases. Sections of the paper provide the following: (1) a description of regression analysis focusing on the specific features that make it appropriate for use in discrimination lawsuits; (2) a review…

Torrance's longitudinal study predicting adult creative achievement was reexamined employing a multiple regression analysis. Application to 211 cases found that 4 predictors explained 49% of the total variance in adult creative achievement. They were creativity test score, childhood future career image, intelligence test score, and the existence…

This study examined whether differences exist in the adjustment of young adults in community settings across levels of mental retardation for four dependent variables, using parametric multivariate analysis of variance, nonparametric multivariate analysis of variance, multiple nonparametric analyses of variance, and multinomial logistic…

Two approaches for conceptualizing and estimating a contextual model for analyzing student achievement are the separate equation approach and the single equation approach. The separate equation method determines the relationship between the individual-level independent variable and the individual-level dependent variable within each group. It then…

Maintains that there is an inconsistency in the regression analysis of the data presented in Maureen J. Lage and Michael Treglia's 1996 article, "The Impact of Integrating Scholarship on Women into Introductory Economics." The authors admit the error, correct it, and report no difference in their original conclusions. (MJP)

Rectifies the unsatisfactory textbook treatment of the finite-sample proprieties of estimators of regression models with a lagged dependent variable and autocorrelated disturbances. Maintains that the bias of the ordinary least squares estimator is determined by the dynamic and correlation effects. (MJP)

This paper describes an initial effort to provide a carefully reasoned, factually based, systematic analysis of teacher pay in comparison to pay in other occupations available to college-educated workers. It also reports on the sensitivity of these salary comparison estimates to differences in certain characteristics of the labor force, such as…

What percent of Americans have been exposed to arts education? Has it changed over time? How do demographic characteristics correlate with arts education? What is the state of arts education in U.S. schools? These research questions are the focus of this report, which is presented in two parts. Using data from the Surveys of Public Participation…
