This study was designed to derive the distribution of a test statistic based on normal probability plots. The first purpose was to provide an empirical derivation of the critical values for the Line Test (LT) with an extensive computer simulation. The goal was to develop a test that is sensitive to a wide range of alternative distributions,…

Computers can be used in elementary statistics courses not only to perform calculations, but also to perform simulations to clarify concepts and theorems. Computer programs for a sample distribution of the mean and for the central limit theorem are given and discussed. (MNS)

Simulations and games are designed to provide participants with an experiential context for reflection and learning in classrooms, corporate training centers, and community-based organizations. A conversational approach to debriefing sessions is one way to more deeply involve participants in exploring the meaning of their experience from multiple…

Factors in successful implementation of simulation in construction education are as follows: (1) considering human factors and feedback effects; (2) focusing on tradeoffs between with managerial decisions and construction policies; and (3) developing a standalone tool that runs on any platform. Case studies demonstrated the effectiveness of these…

Command and Control Training Using Simulation (CACTUS) is a computer digital mapping system used by police to manage large-scale public events. Audio and video records of adaptive training scenarios using CACTUS show how the simulation develops decision-making skills for strategic and tactical event management. (SK)

Efforts to teach basic helping skills to counselors in training using computer assisted simulation continue to evolve. Recent commercial releases include integration of compressed video and text to allow students to view client/counselor interactions and make choices regarding response categories. (Contains 28 references.) (Author)

A convention commonly used to describe interaction effects within moderated regression frameworks was examined through logical exposition and a Monte Carlo approach to simulate various moderator conditions. Results, which indicate that the convention may lead to incorrect inferences, are discussed in terms of interpreting moderator effects. (SLD)

Virtual Reality (VR) is a computer-created sensory experience that so completely immerses participants that they barely can distinguish this "virtual" experience from a real one. VR promises trainers the ultimate method of simulation. (Author)

Responses to a 50-item, 4-choice test were simulated for 1,000 examinees under conventional formula-scoring instructions. Based on 192 simulation runs, formula scores and expected formula scores were determined for each examinee allowing and not allowing for inappropriate omissions. (TJH)

Exact testing was evaluated as a method for conducting Mantel-Haenszel differential item functioning (DIF) analyses with relatively small samples. A series of computer simulations found that the asymptotic Mantel-Haenszel and the exact method yielded very similar results across sample size, levels of DIF, and data sets. (SLD)

Presents a connectionist approach to modeling that relies on neural networks to control conventional simulations of multimedia clinical patient simulations. These neural networks simplify the medical expert's task of validating and maintaining patient simulations with diagnostic capabilities and serves as the basis of clinical decision support…

A simulation study compares nonhierarchical clustering capabilities of a class of neural networks using Kohonen learning with a K-means clustering procedure. The focus is on the ability of the procedures to recover correctly the known cluster structure in the data. Advantages and disadvantages of the procedures are reviewed. (SLD)

Reviews the literature concerning practical computer-based simulation systems for the management of construction projects and/or firms and describes a conceptual model of a prototype system that simulates the decision making of construction site management. Research and development required to produce the system for use in industry is discussed.…

Virtual reality, a three-dimensional simulation technology, may best be used (1) when training mistakes would be costly; (2) when the environment cannot be experienced in the real world; (3) to improve human-machine interfaces; (4) to make training situations real; and (5) to make the perceptible imperceptible. (SK)

Effectiveness of jackknife methods in reducing bias in estimation of the log-1 autocorrelation parameter p1 was evaluated through a Monte Carlo study using sample sizes ranging from 6 to 500. These estimates appear less biased in the small sample case than many that have been investigated recently. (SLD)
