Overlap-based measures are increasingly applied in the synthesis of single-subject research. This article considers two criticisms of overlap-based metrics, specifically that they do not measure magnitude of effect and do not adequately correspond with visual analysis. It is argued that these criticisms are based on fundamental misconceptions…

Statistical analysis is one component that cannot be avoided in a quantitative research. Initial observations noted that students in higher education institution faced difficulty analysing quantitative data which were attributed to the confusions of various variable measurements. This paper aims to compare the outcomes of two approaches applied in…

The Journal of Agricultural Education (JAE) requires authors to follow the guidelines stated in the Publication Manual of the American Psychological Association [APA] (2009) in preparing research manuscripts, and to utilize accepted research and statistical methods in conducting quantitative research studies. The APA recommends the reporting of…

In the current study, momentary time sampling (MTS) and partial-interval recording (PIR) were compared to continuous-duration recording of stereotypy and to the frequency of self-injury during a treatment analysis to determine whether the recording method affected data interpretation. Five previously conducted treatment analysis data sets were…

Magnitude of effect measures (MEMs), when adequately understood and correctly used, are important aids for researchers who do not want to rely solely on tests of statistical significance in substantive result interpretation. The MEM tells how much of the dependent variable can be controlled, predicted, or explained by the independent variables.…

Differences in science achievement between males and females have been examined either directly or indirectly in a variety of studies. This investigation reviewed a quantitative synthesis of correlational research on science affect, ability, and achievement conducted by Steinkamp and Maehr. Their findings were reassessed by employing a…

Reviews three areas of limitations in the comparative evaluations of early intervention alternatives for disabled children presented in this volume: (1) inaccurate outcomes measures; (2) a misconception of parent training programs as representing true family involvement; (3) and the lack of control over the integrity of treatment given study…

Examines the discussion surrounding the establishment of a reliable transfer rate measure by outlining the major arguments advanced by scholars and researchers in the field. Discusses traditional models of calculating transfer rates, their strengths and weaknesses, and introduces nontraditional transfer rate models. (24 citations) (AJL)

Discusses the difficulty in obtaining transfer rates due to the disagreement over definitions of "transfer." Compares different options to show how manipulating the pool of eligible transfer students influences transfer rates. Describes transfer-ready models for calculating transfer eligibility rate, as well as the Student Right-to-Know formula.…

Deliberations about social policy often center on estimates of harm or benefit generated by different interest groups. Problems in what is measured and how it is measured are illustrated by a discussion of research into sexual abuse and rape. Advocacy research is an unreliable foundation for social policy formation. (SLD)

The findings of the Cost, Quality, and Child Outcomes (CQO) study in Child Care Centers, the largest and most visible child care research conducted in the 1990s, were widely publicized and used to promote increased spending on initiatives to improve child care quality, the redesign of subsidy systems to provide quality incentives, more stringent…

This book provides conceptual and practical strategies for the data and information collection and analysis needs of a diverse group of institutions, ranging from small rural community colleges to large urban research institutions. The model framework is designed for use by any size or type of institution and gives a broad overview of various…

The contribution of occupational profiling to explaining and forecasting job satisfaction were analyzed by using data on job satisfaction for 33,249 workers from waves 1-7 of the British Household Panel Survey. Overall job satisfaction gradients were defined for major and minor groups of occupations in the United Kingdom's Standard Occupational…
