Discusses criticisms of null hypothesis significance testing (NHST), suggesting that historical use of NHST was reasonable, and current users should read Sir Ronald Fisher's applied work. Notes that modifications to NHST and interpretations of its outcomes might better suit the needs of modern science. Concludes that NHST is most often useful as…

In two studies, 10-year-olds from 2 German special schools as well as typically developing children of the same chronological age (CA controls) or the same mental age (MA controls) were compared on several aspects of working memory functions (i.e., size and input quality of the phonological store, speed and automatic activation of the subvocal…

The major purpose of this paper was to examine the quality of various aspects of higher education in the private sector of Pakistan by adopting a descriptive method of research. The population of the study constituted 270 administrators, 6,180 teachers and 61,108 students in existing 54 private universities and degree-awarding institutions of…

The research presented in this report examines the effect of prison-based postsecondary education (PSE) on offenders both while incarcerated and after release. Urban Institute researchers worked with the staff of four institutions in three states to conduct inmate focus groups and stakeholder interviews to explore the motivations for enrolling in…

The present study examined the concerns of teacher candidates in an early field experience. Thirty-five teacher candidates completed the Teacher Concerns Checklist (TCC, Fuller & Borich, 2000) at the beginning, middle and end of their early field experiences. Results showed that teacher candidates ranked impact as the highest concern, self as…

The authors surveyed the faculty teaching in AACSB-accredited accounting programs and examined how their publication rates varied by years-after-completing-dissertation, professorial rank, major research area, type of degree-granting institution, and gender. Using standard statistical methods, the authors found that only…

This study was aimed at finding out if the level of performance of selected Jamaican Grade 12 students on an achievement test on the concept of genetics was satisfactory; if there were statistically significant differences in their performance on the concept linked to their gender, self-esteem, cognitive abilities in biology, school-type and…

Understanding and promoting physical activity is critical to combat the growing obesity epidemic in the U.S. This study was designed to compare two 10-week physical activity programs among college students. One hundred and thirty-six undergraduate college students participated in this randomized posttest only control group study. Seventy-seven…

The present study examined the relationship between reading ability (i.e., reading comprehension and reading vocabulary) and academic procrastination among 120 African American graduate students. A canonical correlation analysis revealed statistically significant and practically significant multivariate relationships between these two reading…

The purpose of the present study was to explore the effect of both short- and long term Child-Centered Play Therapy on teacher-student relationship stress. Teachers identified 58 students exhibiting emotional and behavioral difficulties who were randomly assigned to one of two treatment groups. Students in the short-term intensive play therapy…

Effect sizes are critical to result interpretation and synthesis across studies. Although statistical significance testing has historically dominated the determination of result importance, modern views emphasize the role of effect sizes and confidence intervals. This article accessibly discusses how to calculate and interpret the effect sizes…

Controversy over the merits of Null Hypothesis Statistical Significance Testing (NHST) as a tool for advancing knowledge in the social sciences has intensified in recent years. Literature for and against the use of statistical significant tests is reviewed and three major limitations of these tests are summarized. The first is that "p"…

Procedures developed by Joreskog for studying similarities and differences in factor structures between different groups were applied to data from a study by Thurstoen to investigate the sampling stability of a hypothesized isolated configuration. The hypothesis of an isolated configuration was rejected but not by much. (Author/RC)

Focuses on the procedures available for substituting a special predictive coding method for some of the more complex general regression procedures. (Author)
