Focuses on rape prevalence research and examines the relationship between measurement methods and levels of rape detection. Weighs the relative threat to the validity of prevalence estimates posed by fabrication versus nondisclosure. Examines various methodological choices and their relationship to the magnitude of prevalence estimates. (JPS)

Twelve trained observers were randomly assigned to one of two methods of data collection in scoring teacher-student interactions. Results indicated no overall difference in observer accuracy between momentary time sampling and continuous data collection when scoring behaviors that differed along the dimensions of frequency and predictability.…

In this paper, a data perturbation method for minimizing the possibility of disclosure of participants' identities on a survey is described in the context of the National Assessment of Educational Progress (NAEP). The method distinguishes itself from most approaches because of the presence of cognitive tasks. Hence, a data edit should have minimal…

This report serves as the survey documentation for the design and implementation of the 2003-04 Schools and Staffing Survey. Topics covered include the sample design, survey methodology, data collection procedures, data processing, response rates, imputation procedures, weighting and variance estimation, review of the quality of data, the types of…

This document provides a summary and evaluation of the methodological procedures and results of the full-scale implementation of the Beginning Postsecondary Student Longitudinal Study Second Follow-up, 1990-94 (BPS:90/94). The study was conducted for the National Center for Education Statistics by Research Triangle Institute with the assistance of…

This manual is intended for managers of training and institutional development programs. Its objective is to provide clear and practical advice for those who conduct impact evaluations. Impact evaluation is distinguished from other types of evaluation by the area of the program on which it focuses, the assessment of the extent to which a program…

The original normative base for the Minnesota Multiphasic Personality Inventory (MMPI) was established in the late 1930's and early 1940's. While there was a refining of this original sample in 1957, no contemporary standards for normal people have been published. To develop new norms a random sample of 1,919 households in and near Rochester,…

Possible bias due to sampling problems or low response rates has been a troubling "nuisance" variable in empirical research since seminal and classical studies were done on these problems at the beginning of this century. Recent research suggests that: (1) earlier views of the alleged bias problem were misleading; (2) under a variety of fairly…

Parametric analysis of covariance was compared to analysis of covariance with data transformed using ranks. Using a computer simulation approach the two strategies were compared in terms of the proportion of Type I errors made and statistical power when the conditional distribution of errors were: (1) normal and homoscedastic, (2) normal and…

This book presents hands-on information on how to plan, administer, and analyze opinion polls. Guidance is also offered on how to make this strategy accessible to public interest groups. Several examples, checklists, warnings of possible pitfalls, and lists of material and human resources occur throughout the chapters. Major sections address the…

Written in response to a request by the U.S. General Accounting Office (GAO) for information on the extent to which federal agencies are not complying with the clearance provisions of the Paperwork Reduction Act of 1980, this brief narrative report presents the results of an Information Management and Technology Division survey of 90 out of 2,551…

In spite of impressive expansion in the educational systems of the Arab Middle East countries, educational research in that region is slow to mature. A number of practical and theoretical problems responsible for the slow development of educational research are identified and discussed. (Editor)

A study was conducted to develop a comprehensive program costing model for vocational education. This model produced a comparison between the cost of operating a given vocational program and the average aggregate cost of operating all basic education programs. The model is applicable for both the secondary and postsecondary level programs and can…

One solution to the problem of obtaining test scores in order to assess multiple outcomes of educational programs is a basically simple technique called matrix sampling. Matrix sampling is the estimation of total test score statistics by administering random subsets of test items to randomly selected students. This chapter lays out the specific…

The sampling designs and procedures used by the National Assessment of Educational Progress in its second year assessment activities are documented. The report is organized in three parts. Project objectives and other background information are discussed in the first section. The details of the second year school and household samples are…
