Multiple-group confirmatory factor analysis (MG-CFA) is among the most productive extensions of structural equation modeling. Many researchers conducting cross-cultural or longitudinal studies are interested in testing for measurement and structural invariance. The aim of the present paper is to provide a tutorial in MG-CFA using the freely…

One goal of Extension is to provide practical information that makes a difference to producers. Cow Herd Appraisal Performance Software (CHAPS) has provided beef producers with production benchmarks for 30 years, creating a large historical data set. Many such large data sets contain useful information but are underutilized. Our goal was to create…

In the 21st century, the age of information and technology, there is an increasing importance to statistical literacy for everyday life. In addition, education innovation and globalisation in the past decade in Europe has resulted in a new perceived complexity of reality that affected the curriculum and statistics education, with a shift from…

For many years, students have been taught to visualise data by drawing graphs. Recently, there has been a growing trend to teach statistics, particularly statistical concepts, using interactive and dynamic visualisation tools. Free down-loadable teaching and simulation software designed specifically for schools, and more general data visualisation…

We discuss the learning goals, content, and delivery of a University of Plymouth intensive module delivered over four weeks entitled MATH1608PP Understanding Big Data from Social Networks, aimed at introducing students to a broad range of techniques used in modern Data Science. This module made use of R, accessed through RStudio, and some popular…

The expertise reversal effect occurs when learner's expertise moderates design principles derived from cognitive load theory. Although this effect is supported by numerous empirical studies, indicating an overall large effect size, the effect was never tested by inducing expertise experimentally and using instructional explanations in a…

Mondrian is state-of-the-art statistical data visualization software featuring modern interactive visualization techniques for a wide range of data types. This article reviews the capabilities, functionality, and interactive properties of this software package. Key features of Mondrian are illustrated with data from the Programme for International…

Purpose: This paper seeks to analyse the effectiveness and impact of how Google currently trains its new software engineers ("Nooglers") to become productive in the software engineering community. The research focuses on the institutions and support for practice-based learning and cognitive apprenticeship in the Google environment.…

Back in the 1990s Malcolm Coulthard announced the beginnings of an emerging discipline, "forensic linguistics", resulting from the interface of language, crime and the law. Today the courts are more than ever calling on language experts to help in certain types of cases, such as authorship identification, plagiarism, legal interpreting…

Using Excel, an interactive program is designed to simulate the Solow and endogenous growth models to facilitate the understanding of these models for students of growth theory and macroeconomics.

META-RAND, a Statistical Analysis System macro that generates random values used for calculating correlations in a meta analysis, is described. Output consists of uncorrected and corrected mean and variances of "r" and several measures of the degree of homogeneity or heterogeneity in the data. (SLD)

Provides statistical data on numbers of computers in schools, distribution of computers, use of software packages, teachers' use of technology, lesson time spent using information technology, usefulness of information technology for teaching and learning, and expertise and confidence of teachers. (ASK)

Focuses on problems in making machine-readable data files (MRDFs) accessible and in using them: quality of data in MRDFs themselves (social scientists' concern) and accessibility--availability of bibliographic control, quality of documentation, level of user skills (librarians' concern). Skills needed by social scientists and librarians are…

Focuses on four issues related to providing government numeric databases in libraries: hardware, access software, staff skills, and organizing services. Basic, intermediate, and advanced levels of service and a guide for selecting an appropriate level are presented. Examples of screens from actual searches are included. (Contains eight…

Describes collection-development strategies for use in the identification, evaluation, and selection of numeric-data resources. Addresses three primary issues: the delineation of collecting scope and organizational role; the identification of potentially relevant data resources; and the evaluation of those resources in accordance with objective,…
