We surveyed researchers in the health and exercise sciences to explore different areas and magnitudes of bias in researchers' decision making. Participants were presented with scenarios (testing a central hypothesis with p = 0.06 or p = 0.04) in a random order and surveyed about what they would do in each scenario. Participants showed significant…

A procedure modelling ideal classical and quantum gases is discussed. The proposed approach is mainly based on the idea that modelling and algorithm analysis can provide a deeper understanding of particularly complex physical systems. Appropriate representations and physical models able to mimic possible pseudo-mechanisms of functioning and having…

Computer simulations were employed to investigate sample sizes needed for item analysis when one's primary purpose is to rank order items in terms of indices of quality or to compare indices of quality against a fixed criterion. Necessary sample sizes were much smaller than those indicated by the literature. (Author/JKS)

This simple method for simulating the Central Limit Theorem with students in a beginning nonmajor statistics class requires students to use dice to simulate drawing samples from a discrete uniform distribution. On a chalkboard, the distribution of sample means is superimposed on a graph of the discrete uniform distribution to provide visual…

Describes a simulation of OCLC's TAPECON retrospective conversion service and its impact on an online catalog in a large university research library. The analysis includes results of Library of Congress Card Numbers, author/title, and title searches, and hit rates based on an analysis of OCLC and locally generated reports. (three references)…

Describes how a computer program which simulates four techniques of town sampling can be used to teach survey sampling in a college level social research methods course. (Author/DB)

The third workshop on marine ecosystem modeling is one in a sequence of activities designed to promote modeling as a research and management tool among Mediterranean marine scientists. Previous workshops served mainly as a forum for a familiarization with modeling, while this workshop focused on specific implementation of modeling technology. The…

A fictitious community of 583 households was set up to simulate a survey population, and was used in two laboratory assignments where students "interviewed" householders by a quota sampling procedure and tested the performance of several probability sampling designs. (Author/JEG)

Analysis of a two-way sample of means is considered when corresponding population means are believed a priori to satisfy a partial order restriction. Simulation and the Gibbs sampler are used to summarize posterior distributions, and the posterior distribution is used to predict GPAs of first-year students at University of Iowa. (SLD)

The basic communication theory course offered at Central Michigan University is designed to provide students with an understanding of fundamental concepts and terminology, and to expose them to theory and research in communication. The course gives students the opportunity to engage in simulations and other in-class activities, thus making…

This social psychological laboratory activity permits the systematic observation of spontaneous human behavior as simulated on television and provides one way to effectively demonstrate and compare time sampling, event sampling, and trait rating techniques. The preparation involves videotaping a popular television show that depicts observable…

A study tested a resampling methodology (bootstrap simulation) by examining the effects of class size and student motivation on students' ratings of teaching effectiveness. Results suggest that evaluations based on student ratings should look at more than class averages, and that class size and student motivation affect overall ratings. Examples…
