Rates of screening, brief intervention, and referral to treatment (SBIRT) for alcohol and drug use by physicians remain low, despite evidence of efficacy. Motivational enhancement therapy (MET) may be a promising means to help physicians resolve ambivalence about intervening with alcohol and drug users and take advantage of educational…

Hypothesis testing is one of the more difficult concepts for students to master in a basic, undergraduate statistics course. Students often are puzzled as to why statisticians simply don't calculate the probability that a hypothesis is true. This article presents an exercise that forces students to lay out on their own a procedure for testing a…

Alpha-Max is a multiple comparison procedure that is based on the Bonferroni inequality. However, rather than using preset adjusted alpha values for each pairwise contrast, Alpha-Max bases the decisions on the actual p-values for the pairwise contrasts. After a significant omnibus F-test, the pairwise p-values are determined and ordered from…

The fail-safe N is typically a "what if" analysis applied to studies rather than to a single study. This statistical procedure provides information regarding the stability of a meta-analysis by demonstrating how many nil-null articles would be needed to change the statistically significant results to a statistically nonsignificant…

The recent American Psychological Association Task Force on Statistical Inference report suggested that confidence intervals should always be reported. Other researchers also agree that confidence intervals should be used as a supplement to statistical significance testing. The confidence interval is defined as a range of values constructed around…

Presents a review of fundamental concepts and applications used to address the Behrens-Fisher problem (W. Behrens, 1929 and R. Fisher, 1935), a problem in testing the difference between two population means, through fiducial, Bayesian, and frequentist approaches. (Contains 86 references.) (SLD)

A walk through Milne's Enchanted Forest leads to an unexpected encounter with hypothesis testing.

The current study aimed at investigating the effect of using the story-mapping technique on developing tenth grade students' short story writing skills in EFL. The study attempted to answer the following questions: (1) What are the short story writing skills needed for tenth grade students in EFL?; and (2) What is the effect of the using the…

Recent and ongoing research has demonstrated the alarming likelihood of children from low-income homes and from ethnic minorities to read at much lower reading levels than their peers. Additionally, reading ability is related to the earliest of emergent literacy skills, which can be measured in young children before they enter formal schooling.…

The purpose of this mixed methods study was to examine the academic achievement implications for developmental community college students taking an introductory business course when instruction was differentiated in order to make course content more accessible. The research questions guiding this study looked at the relationship between…

Phase II provides a more detailed examination of classroom variables important to achievement in Oklahoma schools. Where Phase I addressed all nine of the Oklahoma essential elements using survey data, Phase II focuses on what occurs in Oklahoma classrooms primarily using data from principal interviews, classroom observations (on-site), and video…

The purpose of this study was to examine the impact of an engineering mentorship program on African-American male high school students' perceptions of engineering as a viable career choice. In this study, indicators included students' perceptions of engineering, their self-efficacy in the area of mathematics, and their self-efficacy in the area of…

Widespread replications of evidence-based prevention programs (EBPPs) prompt prevention scientists to examine program implementation adherence in real world settings. Based on Chen's model (1990), we identified five key factors of the implementation system and assessed which characteristics related to program adherence. The sample included 32…

Social capital is a useful theory for understanding the experiences of working class, first-generation college students. Social capital is the value of a relationship that provides support and assistance in a given social situation. According to social capital theory, networks of relationships can aid students in managing an otherwise unfamiliar…

College student notes were analysed with respect to the amount of words copied directly, omitted and added to the teacher's overheads or PowerPoint slides in order to understand the effect of teacher scaffolds on student generative learning during initial encoding. Scores on quizzes taken at the end of classes from which notes were collected were…
