An in-class activity is described that can be used not only to motivate hypothesis testing, but also to understand and compute the p-value and power in a statistical test. (Contains 3 figures.)

This article tackles the problem of what should be done with real textual data that are contaminated by errors of recording, particularly when the data contain words that are misspelt, unintentionally or otherwise. (Contains 5 tables and 2 figures.)

This study serves as a teaching aid for teachers of introductory statistics. The aim of this study was limited to determining various sample sizes when estimating population proportion. Tables on sample sizes were generated using a C[superscript ++] program, which depends on population size, degree of precision or error level, and confidence…

A basic understanding of statistical ideas, and especially the idea of statistical modelling involving exposure to statistical data analysis, is as fundamental to an understanding of modern society and its artefacts as is language literacy. Thus, statistics should become a central feature of the mathematics curriculum. This implies, among other…

Using data to redesign instruction is a means of increasing student achievement. Educators in Camden County (Georgia) Schools have used data from benchmark testing since 1999. They hired a commercial vendor to design a benchmark test that is administered four times a year and use the data to generate subject-area reports that can be further…

Methods for meta-analysis have evolved dramatically since Gene Glass first proposed the term in 1976. Since that time statistical and nonstatistical aspects of methodology for meta-analysis have been developing at a steady pace. This guide is an attempt to provide a practical introduction to rigorous procedures in the meta-analysis of social…

Introducing students to measurement concepts poses unique instructional challenges; yet, the importance of measurement issues for all data collection scenarios (e.g., the classroom, individual clients, sporting events) requires that students understand the value of basic measurement procedures. Illustrating the basic measurement topics of…

Describes primary and supplemental textbooks on nonparametric statistics. Lists conceptual and applied articles using these techniques. Recommends using the Statistical Package for the Social Sciences (SPSS-X) computer statistical analysis program. (CFR)

This set of 82 summaries is based on papers written between 1963 and 1982 concerning the Test of English as a Foreign Language (TOEFL). TOEFL is currently required by more than 2,500 colleges and universities in the United States and Canada to determine the English proficiency of applicants whose native language is not English. It is also required…

Asserts that traditional approaches to multivariate analysis, including standard linear regression techniques, ignore the special character of count data. Explicates three suitable alternatives to standard regression techniques, a simple Poisson regression, a modified Poisson regression, and a negative binomial model. (MJP)

A teaching strategy used by geography teachers and librarians at the University of Northern Iowa to teach geography students how to locate statistical data collected and published by the U.S. government is described. (RM)
