The sampling approach [Fiedler, K. (2000a). "Beware of samples! A cognitive-ecological sampling approach to judgment biases." "Psychological Review, 107"(4), 659-676.] attributes judgment biases to the information given in a sample. Because people usually do not monitor the constraints of samples and do not control their judgments accordingly,…

The Programme for International Assessment of Adult Competencies (PIAAC) will establish technical standards and guidelines to ensure that the survey design and implementation processes of PIAAC yield high-quality and internationally comparable data. This document provides a revised version of the technical standards and guidelines originally…

In this paper, an interactive teaching approach to introduce the concept of sampling distributions using the statistical software program, R, is shown. One advantage of this approach is that the program R is freely available via the internet. Instructors can easily demonstrate concepts in class, outfit entire computer labs, and/or assign the…

This report presents data from the 2006 Survey of Doctorate Recipients (SDR). The SDR is a panel survey that collects longitudinal data, biennially, on demographic and general employment characteristics of individuals who have received a doctorate in a science, engineering, or health field from a U.S. academic institution. Sampled individuals are…

Adjustment methods such as propensity scores and analysis of covariance are often used for estimating treatment effects in nonexperimental data. Shadish, Clark, and Steiner used a within-study comparison to test how well these adjustments work in practice. They randomly assigned participating students to a randomized or nonrandomized experiment.…

Curriculum-based measurement of reading (CBM-R) is used to estimate oral reading fluency. Unlike many traditional published tests, CBM-R materials are often comprised of 20 to 30 alternate forms/passages. Historically, CBM-R assessment materials were sampled from curricular materials. Recent research has documented the potentially deleterious…

In a post mortem study, it is demonstrated that linear prediction is as effective as computing a negative hyper-geometric distribution for estimating test norms following matrix sampling from a total test with a highly skewed score distribution, provided the same prediction coefficient is used for all examinee groups. It is also demonstrated…

Selected parameters for a negatively-skewed and a normally distributed normative distribution were estimated in a post-mortem item-examinee sampling investigation. Manipulated systematically were number of subtests, number of items per subtest, and number of examinees responding to each subtest. Each item-examinee sampling procedure was replicated…

This study investigated relationship between self-concept and academic achievement of bachelor degree students. Female students at bachelor were considered the target population. A sample of 1500 students was selected by using two stage cluster sampling technique. An amended form of Self-Descriptive Questionnaire developed by Marsh (1985) was used…

Institutions of Higher Education (IHEs) have increasingly committed to become more sustainable in recent years. Despite this commitment, academic publications in the sustainability field assert that progress has been slower at IHEs than expected and that most IHEs have found sustainability initiatives difficult to implement. Comprehensive…

Developed for an NIH training institute, this volume is organized around the most frequently asked questions by researchers starting their careers in applied research in child and adolescent development. With contributions from the leading scholars in the field, actual research experiences highlight the challenges one faces in conducting such…

Major innovations are becoming available for research in language development and disorders. Among these innovations, recent tools allow naturalistic recording in children's homes and automated analysis to facilitate representative sampling. This study employed all-day recordings during the 2nd year of life in a child exposed to three languages,…

Objective: A multidisciplinary preventive parent mentoring intervention was applied through home visiting with high-risk families receiving well-baby health care. Two implementations were examined for effectiveness. Method: The first implementation employed a quasiexperimental nonequivalent group design, whereas the second used a randomized…

A single group (SG) equating design with nearly equivalent test forms (SiGNET) design was developed by Grant (2006) to equate small volume tests. The basis of this design is that examinees take two largely overlapping test forms within a single administration. The scored items for the operational form are divided into mini-tests called testlets.…

I have adopted complementary approaches to inferring human demographic history utilizing human and non-human genetic data as well as cultural data. These complementary approaches form an interdisciplinary perspective that allows one to make inferences of human history at varying timescales, from the events that occurred tens of thousands of years…
