Growing life expectancy and changes in financial, marriage and labour markets have placed the income position of the elderly at the center of scientific and political discourse. As a consequence, the last decades witnessed the publication of various influential reports that contained comparative statistics on old age income inequalities on the…

Visual display of reported impacts is a valuable aid to both reviewers and readers of systematic reviews. Forest plots are routinely prepared to report standardised effect sizes, but where standardised effect sizes are not available for all included studies a forest plot may misrepresent the available evidence. Tabulated data summaries to…

This study applies the theory of planned behavior (TPB), a theory that is commonly used in commercial settings, to the educational context to explain pre-service teachers' technology acceptance. It is also interested in examining its validity when used for this purpose. It has found evidence that the TPB is a valid model to explain pre-service…

Although response to intervention (RTI) has been widely discussed in education literature and is increasingly being implemented in schools throughout the U.S., few studies provide empirical evidence of improved school-wide student outcomes. Presented here are data and an effect size analysis of school-wide student reading gains in five elementary…

This article presents a review of the "Psychosocial Evaluation and Threat Risk Assessment" (PETRA), a 60-item self-report instrument "designed to address the psychosocial characteristics most commonly associated with acts of school violence" among middle school and high school students ages 11 to 18 years. The PETRA was…

Avoiding statistical mistakes is important for educators at all levels. Basic concepts will help you to avoid making mistakes using statistics and to look at data with a critical eye. Statistical data is used at educational institutions for many purposes. It can be used to support budget requests, changes in educational philosophy, changes to…

This paper documents a successful methodology for the validation of data in general and for evaluating educational finance data in particular. The report addresses the errors found as a result of the independent completion of Part B-1 of the Elementary-Secondary General Information System (ELSEGIS)--the Local Education Agency Fiscal Report. This…

Due to the paucity of research on struggling adult readers, researchers rely on child-based reading constructs and measures when investigating the reading skills of adults struggling with reading. The purpose of the two studies in this investigation was to evaluate the appropriateness of using child-based reading constructs and assessments with…

The aim of this study is to develop a scale to predict intimate partner femicide and severe violence. The sample consists of 1,081 batterer men who were reported to the police station. First, the most significant differences between the severe violence group (n = 269) and the less severe violence group (n = 812) in sociodemographic variables are…

Broad trends in occupational employment have been projected fairly accurately by the Bureau of Labor Statistics and significant improvements have been made in procedures for developing projections. However, accuracy has not increased over time. (JOW)

Background: The risk of developing a negative attitude to communication as a consequence of having a speech disorder has been in focus for decades in research concerning fluency disorders in relation to both children and adults. The Communication Attitude Test (CAT), which was created to measure children's attitudes towards their own…

The purpose of this study was to determine the validity of school and district dropout data and, if possible, to establish an accurate dropout rate for the Dade County Public Schools. Several key school files and documents were examined; prior dropout data were examined; and a survey of school personnel was conducted. The general conclusion of the…

Two computer programs (one batch, one interactive) are designed to provide statistics for a weighted linear combination of several component variables. Both programs provide mean, variance, standard deviation, and a validity coefficient. (Author/JKS)
