Recently, Stephen Gorard has outlined strong objections to the use of significance testing in social research. He has argued, first, that as the samples used in social research are almost always non-random it is not possible to use inferential statistical techniques and, second, that even if a truly random sample were achieved, the logic behind…

We analyzed 2010 US National Emergency Department Sample data and ran regression models to test the hypotheses that individuals with ASD are more likely to have non-traumatic dental condition (NTDC)-related emergency department (ED) visits and to incur greater costs for these visits than those without ASD. There were nearly 2.3 million…

The effective evaluation of correctional programs is critically important. However, research in corrections rarely allows for the randomization of offenders to conditions of the study. This limitation compromises internal validity, and thus, causal conclusions can rarely be drawn. Increasingly, researchers are employing propensity score matching…

In this study, we synthesized the literature on how informal contexts, namely friends and family social groups, shape high school students' likelihood of pursuing advanced math and science coursework. Extending scholarly understandings of STEM education, we turned to the body of literature with three guiding questions: (1) What influence do…

Purpose: Early childhood is of critical importance in terms of cognitive, affective and physical development. Undoubtedly, a substantially stimulating environment and opportunities offered to children, as well as appropriate educational materials, have an impact on their development. The object of this study is to investigate the mathematical…

Risk is a fundamental component of well-being and is interconnected with all aspects of child development. The aim of this paper is to explore children's (N = 50) own perspectives and perceptions of risky situations. Semi-structured interviews were conducted and images were used as prompts. Children aged five to six years were asked to identify…

In this study, we provide updated estimates of the private and social financial return on enrolling in a master's degree program in the United States. In addition to returns for all fields of study, we show estimated returns to enrolling in master's degree programs in business and education, specifically. We also conduct a sensitivity analysis to…

This paper examines the effect of the introduction of an academic dismissal (AD) policy (i.e. an intervention, which can lead to compulsory student withdrawal) on student dropout, student graduation rates and satisfaction with the study program. Using a difference-in-differences type of estimator, we compare programs that introduced an AD policy…

The possibility that the validity of assessment is compromised by repeated sittings of highly competitive and high profile selection tests has been documented and is of concern to stake-holders. An illustrative example is the Undergraduate Medicine and Health Sciences Admission Test (UMAT) used by some medical and dental courses in Australia and…

What factors best explain the low incidence of skills training in a late industrial society like Russia? This research undertakes a multilevel analysis of the role of occupational structure in the probability of training. The explanatory power of occupation-specific determinants and skills polarization are evaluated, using a representative 2012…

This study considers probability models as tools for both making informal statistical inferences and building stronger conceptual connections between data and chance topics in teaching statistics. In this paper, we aim to explore pre-service mathematics teachers' use of probability models for a chance game, where the sum of two dice matters in…

The Scientific Method is the series of processes by which hypotheses, ideas and theories are shown to be true beyond a reasonable scientific doubt. Most science "fact" is expressed in terms of probabilities rather than certainties. Thus, by means of statistical calculations, researchers aim to determine whether an observed association…

This article addresses performance assessments that involve collaboration among students. We apply the Hawkes process to infer whether the actions of one student are associated with increased probability of further actions by his/her partner(s) in the near future. This leads to an intuitive notion of engagement among collaborators, and we consider…

This study tested a theory of planned behavior (TPB)-based model in predicting human papillomavirus (HPV) vaccination intentions and series completion among university students. A nonexperimental, cross-sectional design was utilized with a convenience sample of 281 university students, including 40.9% nonvaccinees, 19.6% vaccine initiators, and…

This report provides an analysis of employer-supported training in Australia. Employer-supported training is the largest share of adult education and training in all Organisation for Economic Co-operation and Development (OECD) countries. It has benefits for individuals, firms, and society. Cross-country studies have shown a positive association…
