Autistic children are less likely to participate in sport than non-autistic children, but we know little about how patterns of participation in team and individual sport change across childhood. Drawing on a nationally representative cohort of Australian children, this study analysed trajectories of participation in team and individual sport…

In statistics classes, the central limit theorem has been demonstrated using simulation-based illustrations. Known population distributions such as a uniform or exponential distribution are often used to consider the behavior of the sample mean in simulated samples. Unlike such simulations, a number of real-data-based simulations are here…

A linear model is often used to find the effect of a binary treatment D on a noncontinuous outcome Y with covariates X. Particularly, a binary Y gives the popular "linear probability model (LPM)," but the linear model is untenable if X contains a continuous regressor. This raises the question: what kind of treatment effect does the…

Global digital advancements provide postsecondary students with ample digital job opportunities. Thus, it is crucial to understand the psychological determinants that affect postsecondary students' choices of a digital career. Self-efficacy and interest are two widely used psychological determinants in the choice behavior of individuals. However,…

Experiments in psychology or education often use logistic regression models (LRMs) when analyzing binary outcomes. However, a challenge with LRMs is that results are generally difficult to understand. We present alternatives to LRMs in the analysis of experiments and discuss the linear probability model, the log-binomial model, and the modified…

This study investigates a range of non-normative ideas that pre-service teachers (PSTs) employ in reasoning about sampling variability. This issue was studied in the context of a content course on statistics and probability for pre-service middle grade teachers at a Midwestern American university. Analysis of seven PSTs' video and screen records…

Turnover in the teacher workforce imposes significant costs to schools, both in terms of student achievement and the time and expense required to recruit and train new staff. This paper examines the potential for structured ratings of teacher applicants, solicited from their professional references, to inform hiring decisions through the selection…

Teaching and learning undergraduate statistics has been a most challenging task for undergraduate psychology majors (Salkind, 2017). A seasoned statistics instructor consulted with a seasoned instructional designer on a method to improve a particularly demanding course using a performance improvement approach to address learning difficulties she…

Background: Universities faced important and sudden changes following the lockdown measures imposed during the COVID-19 pandemic. Traditional educational practices were disrupted as campuses were closed while distance learning was hastily adopted. Aims: This study documents the evolution of university students' autonomous and controlled motivation…

Involuntary musical imagery (INMI; more commonly known as "earworms" or having a song "stuck in your head") is a common musical phenomenon and one of the most salient examples of spontaneous cognition. Despite the ubiquitous nature of INMI in the general population, functional roles of INMI remain to be fully established and…

This study aimed to identify whether appetitive traits predict exclusive breastfeeding (EBF) duration for the first 6 months of life and to assess other predictors of its duration. 186 six- month-old term infants were included. Appetitive traits were assessed at 3-4 months of age. EBF duration, feeding practices, sex, maternal age and education,…

This study examines how college majors are related to marital outcomes through homogamy based on college attainment and fields of study. Grounded in theories of educational assortative mating, opportunity structure, and personal preferences, we investigate how college majors predict marriage probability, spouse selection, and economic inequality…

Although online learning has increased in popularity in higher education, attrition rates in this delivery method are also high. An archival study over a 14-year time period was conducted to (a) compare the drop rates in a face-to-face vs. online introduction to physical geology course and (b) explore possible factors related to the probability of…

Questionnaires inquiring about psychopathology symptoms often produce data with excess zeros or the equivalent (e.g., none, never, and not at all). This type of zero inflation is especially common in nonclinical samples in which many people do not exhibit psychopathology, and if unaccounted for, can result in biased parameter estimates when…

With limited budgets and increasing enrollment demands, colleges need fast, free, and practical solutions supporting academic success and retention. The Academic Reality Check (ARC) tool helps to predict traditional freshmen awareness of their own academic expectations in college quickly, supporting the financial investment being made by all…
