The recent commentary by Beaujean and Farmer (2020) on the original paper by Dixon et al. (2019) serves a cautionary tale of selective p-values, the law of small N sizes, and the type-II error. We believe these authors have crafted a somewhat questionable argument in which only 57% of the original Dixon et al. data were re-analyzed, based on a…

In this commentary from Issue 14, n3, authors John Cadogan and Nick Lee applaud the paper by Aguirre-Urreta, Rönkkö, and Marakas "Measurement: Interdisciplinary Research and Perspectives", 14(3), 75-97 (2016), since their explanations and simulations work toward demystifying causal indicator models, which are often used by scholars…

This letter documents some problems in Ancaiani et al. (2015). Namely the evaluation of concordance, based on Cohen's kappa, reported by Ancaiani et al. was not computed on the whole random sample of 9,199 articles, but on a subset of 7,597 articles. The kappas relative to the whole random sample were in the range 0.07-0.15, indicating an…

Elliot et al. (2010) reported multiple experimental findings that the color red modified women's ratings of attractiveness, sexual desirability, and status of a photographed man. An analysis of the reported statistics of these studies indicates that the experiments lack sufficient power to support these claims. Given the power of the experiments,…

In their "The Prevalence of Mind-Body Dualism in Early China," Slingerland and Chudek use a statistical analysis of the early Chinese corpus to argue for Weak Folk Dualism (WFD). We raise three methodological objections to their analysis. First, the change over time that they find is largely driven by genre. Second, the…

Recently this journal published a research article examining the effectiveness of three different tests in identifying ethnically diverse gifted and talented children (Lewis, DeCamp-Fritson, Ramage, McFarland, & Archwamety, 2007, Volume 15, Number 1, pp. 38-42). After examining the proportions of Caucasian and non-Caucasian children identified…

This article presents the author's address at the 2007 "Journal of Applied Quantitative Methods" ("JAQM") prize awarding festivity. The festivity was included in the opening of the 4th International Conference on Applied Statistics, November 22, 2008, Bucharest, Romania. In the address, the author reflects on three theses that…

Reports on the re-examination of recent underestimates of the number of adoptions of foster care children. Notes that underestimates resulted from under-reporting by states, use of inappropriate data as estimate bases, and real increases in the number of adoptions. (DLH)

Statisticians can help to improve human rights reporting. The statistician's approach to measurement, summary, and interpretation is needed to understand and help reduce human rights violations. Statistical problems in the measurement and analysis of human rights violations include: lack of agreement on the definition; great difficulties in…

Examines and rejects common criticisms of the causality concept; shows causality is a relation implied in the grammar of a language about objects. Discusses objective criteria for concepts of causal relations and explains how the concept of causality may be modified to have causes determine probabilities of outcomes. (Author/RH)

Provides a set of guidelines for evaluating research using structural equation modeling (SEM). Offers insight into how someone familiar with SEM would judge the adequacy of a study using such methods. (Author/RH)

Defines the "unit of analysis" and the "context of analysis" and examines examples of the misuse of these concepts in research articles in the "Educational Administration Quarterly." Discusses the use of various statistics with different analytical units and contexts and makes three recommendations to alleviate the…

Responds to counterpoints to original paper (Moon, Dillon, and Sprenkle, 1990). Describes continuum of social science inquiry paradigms as framework for exploring assumptions underlying respective positions. Addresses key issues raised by respondents and encourages balance in research efforts and continuing dialogue. Restates basic thesis that…

Reviews persistent criticisms of quantitative research methodologies such as the lack of isomorphism between measures and "reality," its failure to produce "truths" useful to educational practice, the faulty use of statistics, and the poorly understood notion of causality. (JDH)

Demonstrates ways in which conclusions about models may be affected by violations of the assumption that the observed variables are normally distributed. Addresses the issue of the robustness of findings obtained under such conditions. (Author/RH)
