Education policy research aimed at eliminating racism necessitates methodological innovation that fosters both equity-centered approaches and robust empirical analysis of the systemic nature of racism. Most quantitative research in educational psychology omits the racist environment that students in K-12 education exist in (DeCuir-Gunby &…

This guide is designed to help researchers make sure that their research reports include enough information about study measures so that readers can assess the quality of the study's methods and results. The guide also provides examples of write-ups about measures and suggests resources for learning more about these topics. The guide assumes…

A special sampling procedure for collecting health statistics and related information from a representative sample of migrant farmworkers was developed for the New York Migrant Health Interview Survey conducted in Wayne County during the summer of 1982. A three-stage, stratified random sampling technique was used. The primary sampling units were…

Suggest practical procedure for estimating number of subjects that need to be screened to obtain sample of fixed size that meets multiple correlated criteria. Procedure described is based on fact that least-squares regression provides good quadratic fit for Monte Carlo estimates of multivariate probabilities when they are plotted as function of…

A guide to survey research is presented for both novice and experienced researchers. Steps of the survey research process are covered: (1) planning the survey to determine the purpose of the study, collecting background information, designing the sample, and making a time line for completing the project; (2) questionnaire design, including the…

Communication samples were collected from 15 normally developing children (ages 11-27 months) during the prelinguistic, single-word, and multiword stages, using both structured and unstructured contexts. Significantly more requests were used during the structured context, but no significant difference was found between the numbers of comments used…

This study comparing momentary time sampling against the real time obtained with handheld computers confirmed laboratory findings that short-elementary time sampling estimates percentage time accurately for a wide range of behavior frequencies and durations, and suggested that observers using momentary time sampling in a natural setting are able…

Since the last comprehensive museum survey was conducted in 1971-72, no current data has been gathered about the museum field. Because the field has not remained static it has become difficult to apply the 1971-72 survey findings to current museum situations. Because of this, the National Center for Education Statistics (NCES) was requested to…

Since meta-analysis was described in 1976 (Glass) as the application of familiar experimental methods to the integration of available research, at least five coherent approaches to meta-analysis have appeared in common use. These approaches can be divided into two broad groups. In the first group (including procedures by Robert Rosenthal, Larry…

The methods of 27 studies focusing on toy play among young children with mental retardation were reviewed. Considerable variability was noted with respect to sample characteristics, contextual parameters, and type of measurement. Researchers frequently neglected to provide potentially useful methodological information. Suggestions for future…

The purpose of this study was to develop a single procedure for comparing population variances which could be used for distribution forms. Bootstrap methodology was used to estimate the variability of the sample variance statistic when the population distribution was normal, platykurtic and leptokurtic. The data for the study were generated and…

A modified time sampling procedure that measured behavioral rate and duration was used to record stereotypic and on-task responding in 11 students (ages 11-17) with severe emotional and behavioral disturbances. For both types of behavior, response duration exhibited less variability than response rate, and noncorrespondence between the two…

A theoretical model proposed by Paul Kantor for determining shelf availability for library materials by checking a small sample of items drawn from the checklist against the stacks and circulation records is applied to a working environment, and the following considerations are examined: (1) time required to apply the model to a working library…

Error profiles for the Fall Enrollment Survey of the Higher Education General Information Survey (HEGIS) were developed as part of an assessment of the quality of survey data. Three statistics were of particular interest: the count of full-time equivalent students, the breakdown by race/ethnicity, and the count of unclassified students. Attention…

Sampling distributions for ten tests for comparing population variances in a two group design were generated for several combinations of equal and unequal sample sizes, population means, and group variances when distributional forms differed. The ten procedures included: (1) O'Brien's (OB); (2) O'Brien's with adjusted degrees of freedom; (3)…
