Autism is heterogeneous, which complicates providing tailored support and future prospects. We aim to identify subgroups in autistic adults with average to high intelligence, to clarify if certain subgroups might need support. We included 14 questionnaire variables related to aging and/or autism (e.g., demographic, psychological, and lifestyle).…

Student socialisation into the norms and environment of their institution is a crucial process during their college experience. During the COVID-19 pandemic, these processes were disrupted, and little published research exists exploring comparisons of these student socialisation processes before and during the pandemic. Accordingly, we report on a…

During the past few decades, Charter schools have been utilized as laboratories for educational innovation. Each year, more and more Charter schools open across the United States. These schools are governed the same way traditional public schools are, but there is research that suggests that inequalities exist in the representation and performance…

Peter Dunn and Margaret Marshman present the second of their data files articles in which they discuss the statistical investigation cycle which describes the whole process of conducting a statistical research study. [For "The Data Files: A Series of Articles to Support Mathematics Teachers to Teach Statistics," see EJ1259108.]

Differential item functioning (DIF) assessment is a crucial component in test construction, serving as the primary way in which instrument developers ensure that measures perform in the same way for multiple groups within the population. When such is not the case, scores may not accurately reflect the trait of interest for all individuals in the…

As social behavior moves increasingly online, the study of social behavior has followed. Online traces of social systems, whether to study online behavior directly or the online traces of offline activity, have made possible previously unavailable empirical analyses of people, groups and organizations. However, practically observing any social…

This paper provides the first population-based evidence on how much standardized test scores vary among public school districts within each state and how segregation explains that variation. Using estimates based on roughly 300 million test score records in math and English Language Arts (ELA) for Grades 3 through 8 from every U.S. public school…

This article reports on gender ratio, age of diagnosis and the duration of assessment procedures in autism spectrum disorder diagnosis in a national study which included all types of clinical services for children and adults. Findings are reported from a retrospective case note analysis undertaken with a representative sample of 150 Scottish…

Recently there has been an increasing level of interest in subtest scores, or subscores, for their potential diagnostic value. Haberman (2008) suggested a method to determine if a subscore has added value over the total score. Researchers have often been interested in the performance of subgroups--for example, those based on gender or…

This study applied kernel equating (KE) in two scenarios: equating to a very similar population and equating to a very different population, referred to as a distant population, using SAT[R] data. The KE results were compared to the results obtained from analogous traditional equating methods in both scenarios. The results indicate that KE results…

Social scientists usually are more interested in consumers' dichotomous choice, such as purchase a product or not, adopt a technology or not, etc. However, up to date, there is nearly no model can help us solve the problem of multi-network effects comparison with a dichotomous dependent variable. Furthermore, the study of multi-network…

Objective: This study investigates whether two patient population groups, under resident or attending treatment, are equivalent or different in the distribution of patient characteristics, diagnoses, or pharmacotherapy. Methods: Demographic data, psychiatric diagnoses, and pharmacotherapy data were collected for 100 random patient charts of…

Fiscal realities are forcing a review and potential refocusing of Illinois community colleges. This study compared the themes that emerged from interviewing an Illinois community college stakeholder group in 2005 to what emerged from a similar study in Iowa by Ebbers and Gardner in 2002. Illinois stakeholders talked about their overall perceptions…

This study compared different stakeholders' perceived validity of various indicators of student learning used to judge the quality of students' academic performance. Data were gathered from the questionnaire responses of 314 educators in three states that have implemented comprehensive state-wide assessment programs with high-stakes consequences…
