Researchers persist in using stepwise regression in spite of problems with this approach. As noted by B. Thompson (1995), three problems accompany the use of stepwise applications. The first is that computer packages may use incorrect degrees of freedom in their computations, resulting in a greater likelihood of obtaining a spurious statistical…

The National Household Education Survey (NHES) is a data collection system of the National Center for Education Statistics. The NHES is a telephone survey of the noninstitutionalized civilian population using households selected using random digit dialing methods. Approximately 60,000 households are screened for each administration, and people who…

As part of a high-risk youth grant from the Center for Substance Abuse Prevention, the Southwest Regional Laboratory developed and implemented a survey of alcohol sales establishments. The purpose was to assess the availability of alcohol in the community and changes in availability over time that may have an impact on findings related to project…

The zeitgeist for reform in education precipitated a number of changes in assessment. Among these are performance assessments, sometimes linked to "high stakes" accountability decisions. In some instances, the trustworthiness of these decisions is based on variance components and error variances derived through generalizability theory.…

In a complex sampling scheme it is desirable to select the primary sampling units (PSUs) without replacement to prevent duplications in the sample. Since the estimation of the sampling variances is more complicated when the PSUs are selected without replacement, L. Kish (1965) recommends that the variance be calculated using the formulas…

Three types of data were factor analyzed using principal components extractions with orthogonal and oblique rotations to test publisher claims for construct validity of the Personal Profile System (PPS). Behavioral descriptor data from 1,045 senior non-commissioned Air Force officers were factored as raw data, mean corrected data, and standardized…

The purpose of this paper is to examine the nature of discrepancy score phenomena of the Myers-Briggs Type Indicator (MBTI), as related to internal consistency and construct validity of the instrument. Data were collected from 140 university research managers. The data suggest internal consistency problems: only 37.3 percent of the subjects…

Research with older persons suffering from physical illness presents numerous challenges to gerontologists. Issues of conceptualization pertaining to the definition of illness, its location in the research paradigm, and the context in which illness occurs must be addressed prior to dealing with methodological problems. Access to physically ill…

This exploratory study was designed to compare three groups within the teaching profession--women school administrators, women teachers matched with administrators on years of teaching experience and teacher education, and women teachers randomly selected--on variables which may be relevant to career decisions.

The purpose of the study was to test the effectiveness of two related strategies for changing a measured disposition of intolerance toward cultural diversity to one of significantly less intolerance. (Editor)

After acknowledging the general ignorance concerning the changes which occur in American undergraduates who study off-campus, either domestically or internationally, the authors describe various studies which have attempted to assess off-campus educational experiences. (Editor)

Restricted sampling with which the Illinois Test of Psycholinguistic Abilities was standardized was investigated by simulating a multivariate population comprised of four variables and having specified means, standard deviations, and intercorrelations. (Author/CL)

The present paper attempts to consider the physical education teacher's role in terms of (a) students' expectations across the years of teacher training; (b) how pupils see the role of the physical education teacher; and (c) the perceptions (and possible reinforcing influences) of classroom colleagues.
