Children acquiring languages with noun classes (grammatical gender) have ample statistical information available that characterizes the distribution of nouns into these classes, but their use of this information to classify novel nouns differs from the predictions made by an optimal Bayesian classifier. We use rational analysis to investigate the…

We present three strategies to replace the null hypothesis statistical significance testing approach in psychological research: (1) visual representation of cognitive processes and predictions, (2) visual representation of data distributions and choice of the appropriate distribution for analysis, and (3) model comparison. The three strategies…

The aim of this article is to propose a new breakdown of the Gini inequality ratio into three components ("within-group" inequality, "between-group" inequality, and intensity of "transvariation" between groups to the total inequality index). The between-group inequality concept computes all the differences in salaries…

This paper sets forth an integrated way of introducing bibliometrics to relatively non-quantitative audiences, such as librarians and iSchool students. The integrative device is the bibliogram, a linguistic object consisting of a seed term and the terms that co-occur with it, ranked by their co-occurrence counts with the seed--a standard…

Describing the variation in test scores between and within school districts is critical for: (1) for policy-related and descriptive work that investigates the sorting of students among districts and the differential effectiveness of those districts; and (2) for methodological work planning future experiments or interventions. Intraclass…

Bloom's taxonomy is probably the most commonly used one among the cognitive process models. It is a classification system that emphasizes the procedures starting from remembering the knowledge to more complex cognitive levels like evaluating the knowledge. Firstly, the aim of this study has been to find out to what extent Bloom's taxonomy is…

van der Linden (this issue) uses words differently than Holland and Dorans. This difference in language usage is a source of some confusion in van der Linden's critique of what he calls equipercentile equating. I address these differences in language. van der Linden maintains that there are only two requirements for score equating. I maintain…

The purpose of this study, which is based on qualitative data, is to reveal the opinions of art teachers on the teacher standards set by the International Society for Technology in Education. It has been observed that the majority of participants of a study group are not aware of these standards, use social networks but do not use mobile…

Quantitative information about test score reliability can be presented in terms of the distribution of equated scores on an alternate form of the test for test takers with a given score on the form taken. In this paper, we describe a procedure for estimating that distribution, for any specified score on the test form taken, by estimating the joint…

Effectively communicating environmental issues to motivate visitors' behavior is critical for zoos to accomplish their missions. We examined the relationship between zoo visitors' environmental concern and agreement with messages framed by environmental concern. Findings from two zoos (N = 298; N = 400), using two message formats, provided nearly…
