Describes a computer program called AnoGen that automates the process of generating data sets for ANOVA designs and operates within DOS and Windows compatible computers. Explains that the program runs in both student and teacher modes and is freely available for noncommercial use through the Internet. (CMK)

A computer program written in BASIC is described which performs one-way analysis of variance based on the mean, standard deviation, and size of each group. Output lists a full analysis of variance table. (Author)

The various costs of Type I and Type II errors of inference from data are discussed. Six methods for minimizing each error type are presented, which may be employed even after data collection for Type I and which minimizes Type II errors by a study design and analytical means combination. (Author/CM)

A program is described utilizing a microcomputer and tape drive with any contingency or chi-square table from 2x2 to 8x8. It requires only the entering of the number of rows and number of columns, plus one-time entry of cell frequencies. (Author/JKS)

The N=1 analysis differs from a typical analysis of variance in that there is no within-cell error term. Thus interaction terms are used as estimates of error variance. If the interaction term in question represents a significant interaction, the F tests will be conservative. Tukey's test for nonadditivity will detect a common form of interaction.…

As an extension of B. Thompson's 1998 invited address to the American Educational Research Association, this paper cites two additional common faux pas in research methodology and explores some research issues for the future. These two errors in methodology are the use of univariate analyses in the presence of multiple outcome variables (with the…

Describes the design and operation of two macros written in the programming language of Microsoft's EXCEL for educational research applications. The first macro determines the frequency of responses to a Likert-type questionnaire or multiple-choice test; the second performs a one-way analysis of variance test. (Author/LRW)

Describes when and how to carry out many of the most common statistical tests including mean, standard deviation, confidence limits, correlation, regression, t-test, Chi square test, and ANOVA. Uses Excel to perform these operations. (DDR)

Reports on the performance of the vector space model in the presence of OCR (optical character recognition) errors in information retrieval. Highlights include precision and recall, a full-text test collection, smart vector representation, impact of weighting parameters, ranking variability, and the effect of relevance feedback. (Author/LRW)

Examines the effects of gender, personality, and keyboard control on foreign language and interaction patterns of 60 intermediate French students in a computer-assisted language learning environment at the university level. Results indicate that learning achievement and interaction patterns at the computer are more strongly related to personality…

The major purposes of this study were (1) to determine the congruence between perceived actual and desired frequency and extent of participation by teachers in the decision-making process; (2) to relate decision participation to teachers' job satisfaction; (3) to relate selected personal and situational variables to decisional participation; and…

Describes a multimedia program for teaching analysis of variance (ANOVA) designs. The program uses colorful images, brief animations, interactive tasks, and immediate feedback. It consists of 10 story problems that tests students' understanding of independent groups and repeated measures variables. Provides information about availability. (MJP)

Notes that salient input facilitates explicit learning by assisting second language (L2) learners to attend to the new L2 forms as they formulate or restructure rules. This study tested the effect of such input on the acquisition of difficult grammatical structures in English by speakers of Hebrew. Concludes that explicit contrastive input…

This report presents an account and evaluation of a two-year survey-feedback problem-solving organization development (OD) project in a small city's school district. The project combined the survey-feedback technology with structural alterations in the school district and the training of internal change agents. Both planned and unplanned events…
