Written by a social worker for social work students, this is a nuts and bolts guide to statistics that presents complex calculations and concepts in clear, easy-to-understand language. It includes numerous examples, data sets, and issues that students will encounter in social work practice. The first section introduces basic concepts and terms to…

In this study, the reasons why men and women behave differently in leadership roles in schools were investigated because of recent research on the indirect nature of the school principal's impact on learning and on gender differences in leadership behaviors. Practicing principals (109 males, 172 females) from two Southwestern states were surveyed…

This study was designed to examine the impact NCLB defined teacher-quality variables (1) major/minor in mathematics, (2) highest academic degree, (3) type of teaching certificate, (4) years taught mathematics (NCLB, 2001) on the mathematics average scale scores of eighth-grade students. The study used a secondary analysis of the 2007 National…

This report provides a description of the student characteristics, persistence, and degree attainment of a nationally representative sample of students who began postsecondary education for the first time during the 2003-04 academic year. The report describes the background, academic preparation, and experience of these beginning students over 3…

Purpose: The purpose of this paper is to identify and measure the perceptions and attitudes of students regarding the classroom performance system (CPS). Design/methodology/approach: The paper reviews a range of recently published (1993-2006) works on pedagogy and educational technology. A survey methodology was utilized to measure students'…

The main aim of this research study was to test out a conceptual model encompassing the theoretical frameworks of achievement goals, study processing strategies, effort, and reflective thinking practice. In particular, it was postulated that the causal influences of achievement goals on academic performance are direct and indirect through study…

There is an increasing need for students in the biological sciences to build a strong foundation in quantitative approaches to data analyses. Although most science, engineering, and math field majors are required to take at least one statistics course, statistical analysis is poorly integrated into undergraduate biology course work, particularly…

The purpose of this article was to extend the research pertaining to the idea of a statistically significant exact replication (SSER) method published recently in the Mid-Western Educational Researcher. The current study continues the idea of SSER and provides researchers with a software program that will calculate easily the SSER value when there…

A selection of statistical problems commonly encountered in psychological or psychiatric research concerning correlation coefficients are re-evaluated in the light of recently developed simplifications in the forms of the distribution theory of the intraclass correlation coefficient, of the product-moment correlation coefficient, and the Spearman…

This paper demonstrates that a meta-analysis technique applied to the Solomon Four-Group Design (SFGD) can fail to find significance even though an earlier "weaker" test may have found significance. The meta-analysis technique was promoted by Braver and Braver as the most powerful single test for analyzing data from an SFGD. They…

A recent survey of simulation studies concluded that an overwhelming majority of papers do not report a rationale for the number of iterations carried out in Monte Carlo robustness (MCR) experiments. The survey suggested that researchers might benefit from adopting a hypothesis testing strategy in the planning and reporting of simulation studies.…

The controversy regarding the admissibility of one-tailed tests of hypotheses was examined. Rather than taking a stand with regard to whether the one-or the two-tailed test is the most seriously flawed, a procedure is developed which can capitalize on the advantages of each. (RC)
