The present article provides a primer on (a) effect sizes, (b) confidence intervals, and (c) confidence intervals for effect sizes. Additionally, various admonitions for reformed statistical practice are presented. For example, a very important implication of the realization that there are dozens of effect size statistics is that "authors must…

Meltsner classified evaluators as technicians, politicians, entrepreneurs, or pretenders, based upon differing expectations norms, training, and motivations. This role-perception study of evaluators in a large urban school district supported Meltsner, although few technicians or politicians emerged. (CP)

Research libraries are increasingly supplementing collection counts with perceptions of service quality as indices of status and productivity. The present study was undertaken to explore the reliability and validity of scores from the SERVQUAL measurement protocol (A. Parasuraman and others, 1991), which has previously been used in this type of…

The study investigated whether school administrators (n=128) implicitly perceive the "types" of evaluators proposed by Meltsner (1976) when they consider evaluative information. One simulated evaluation report was written to represent each evaluator, differentiated from one another by their norms, expectations, motivations, and training.…

The construct validity of three subtests of the Structure-of-Intellect Learning Abilities Test ( (1) Divergent Production of Figural Units (DFU), (2) Divergent Production of Semantic Units, and (3) Divergent Production of Symbolic Relations) was investigated and generally supported, although results were somewhat mixed with respect to the DFU…

Principals from a large public school system recommended actions they would take after reading a conventional program evaluation report. Another group of principals made recommendations after reading a "confidence interval" report. Results indicated that the reporting form did influence decisions about a program's worth. (PP)

Used confirmatory factor analysis to evaluate the score integrity of LibQUALl+, an instrument to measure perceptions of library service quality. Results for 60,027 graduate and undergraduate students suggest that the model implied by LibQUAL is reasonable and invariant across independent samples and fits all three major subgroups of library users.…

The SERVQUAL measure was developed by A. Parasuraman, L. Berry, and V. Zeithaml (1988) to measure perceptions of service quality, originally in the retailing sector. However, libraries and other educational institutions are also service providers. Librarians in particular have increasingly become interested in measuring quality of service as the…

Four instruments were correlated with teachers' percep- tions of elementary school children (N=113). Results suggested that teachers can generate tenable initial estimates of cognitive styles of students. (RC)

Explores the number of dimensions needed to measure users' perceptions of library service quality based on data from the ARL (Association of Research Libraries) LibQUAL+ project. Results were consistent with a view that a single set of scores is one reasonable way to characterize user perceptions of library service quality. (Author/LRW)

This study was conducted to evaluate whether a brief self-description checklist may provide a viable method of quickly obtaining initial personality type information. The Personal Preferences Self-Description Questionnaire (PPSDQ) and the Myers-Briggs Type Indicator (MBTI) were administered to 420 college students, and PPSDQ item-response and MBTI…

Brinkmanship behaviors challenge the authority of a social system while trying to avoid, usually through the use of humor, the sanctions that would normally be provoked. This study investigated the validity and use of short scenarios portraying various teachers challenging policy in different ways as a strategy for measuring perceptions of these…

Investigated the psychometric integrity of scores from the LibQUAL+ evaluation of perceived library service quality conducted by ARL (Association of Research Libraries). Examines score structure, score reliability, score correlation and concurrent validity coefficients, scale means, and scale standardized norms, and considers the potential of the…
