Presents a game to capture student interest in probability by giving them an opportunity to explore the idea of various outcomes and the likelihood of the occurrence of one of those outcomes to explain the benefits of using a large sample rather than a small one. (ASK)

Presents a number of analyses based on the results of the Third International Science and Mathematics Study (TIMSS) in Switzerland. Results show that it's possible to reflect the complicated structure of Swiss secondary education in a sampling design and that there's little growth in mathematics literacy in Swiss upper secondary school students.…

Addresses the lack of data on procedures used to recruit subjects in marital research by examining the effects of different sampling techniques. In Study One, couples recruited through newspaper advertisements were found to be at greater risk for marital discord. In Study Two, couples who responded to mailed solicitation were found to be less…

Describes a class exercise that attempts to alleviate student anxiety and fear of learning statistics. Explains that the exercise focuses on concepts associated with probability sampling theory and sampling distribution through the use of M and M's candy. Describes the four steps involved and additional considerations. (CMK)

Examined the performance of a recently available full information maximum likelihood (FIML) estimator in a multiple regression model with missing data using Monte Carlo simulation and considering the effects of four independent variables. Results indicate that FIML estimation was superior to that of three ad hoc techniques, with less bias and less…

The study examined the application of 1:3 in employments of academic and non-academic staff in Nigerian Universities, as recommended by the National Universities Commission (N.U.C.), following the general feeling that Nigerian Universities were highly bureaucratised; non-teaching staff was over employed while some universities lacked…

Two faculty in business and public and environmental affairs find that students need to move between personal-based experience, data, and a higher level of analytical reasoning. Their teaching of marketing and statistics is shown to benefit from the structured analysis and detailed assessments of the Decoding the Disciplines model.

Transformational approaches to leadership have increasingly been advocated for schools. Research evidence suggests that the effect of leadership on student learning outcomes is mediated by school conditions such as goals, structure, people, and school culture. Using the combined approach of multilevel analysis and structural modeling, this study…

To date most models of empowerment have focused on teachers' personal empowerment, which is defined as intrinsic task motivation reflecting an employee's orientation to his or her work role. Interestingly, little scholarly attention has been turned to the interaction of empowerment and work-team membership, that is, to empowerment acquired from…

Both structural equation models and hierarchical linear models (HLMs) have been commonly used in multilevel analysis. This study utilized simulated data to investigate the power difference among 3 multilevel models: HLM, deviation structural equation models, and a hybrid approach of HLM and structural equation models. Two factors were examined:…

For two random variables, X and Y, let D = X - Y, and let theta[subscript x], theta[subscript y], and theta[subscript d] be the corresponding medians. It is known that the Wilcoxon-Mann-Whitney test and its modern extensions do not test H[subscript o] : theta[subscript x] = theta[subscript y], but rather, they test H[subscript o] : theta[subscript…

Do students accurately perceive the sexual behavior of their peers? The results of this study indicate a dramatic difference between students' self-reported sexual behavior and their perceptions of peer sexual behavior. Specifically, students tend to overestimate the potentially risky sexual activity of their peers. The data also challenge popular…

As the initial phase of a longitudinal study of environmental perspective in college students, resident student opinion was sampled using the New Ecological Paradigm (NEP) scale administered through systematic alphabetical sampling. Sampling was also carried out by a blanket e-mail distribution of surveys for voluntary response. Results showed…

A survey of teachers and principals in Alberta was conducted to gain a descriptive profile of who is teaching physical education (PE) and to assess the relationship between PE specialists and variables associated with program delivery. A probability-sampling procedure was used to obtain a representative sample of schools. In these schools…

The Pearson correlation is used to depict effect sizes in the context of item response theory. Amultidimensional Rasch model is used to directly estimate the correlation between latent traits. Monte Carlo simulations were conducted to investigate whether the population correlation could be accurately estimated and whether the bootstrap method…
