A sample suffers range restriction (RR) when its variance is reduced comparing with its population variance and, in turn, it fails representing such population. If the RR occurs over the latent factor, not directly over the observed variable, the researcher deals with an indirect RR, common when using convenience samples. This work explores how…

In the field of social sciences, certain tasks, such as the identification of typologies and the characterization of groups of individuals according to a set of questions, tend to pose a challenge for researchers. Further complications arise if the chosen rating scale is from 0 to 10, since the responses can be treated either as metric or…

Small samples are common in growth models due to financial and logistical difficulties of following people longitudinally. For similar reasons, longitudinal studies often contain missing data. Though full information maximum likelihood (FIML) is popular to accommodate missing data, the limited number of studies in this area have found that FIML…

The research was designed to examine the effects of question setting using different conditions into 10 sets on the validity of structural equation modeling for factors affecting job morale. The data was collected from 690 personnel working in regional Statistical Offices around Thailand by using cluster random sampling. The tool used in…

Cluster randomized trials involving participants nested within intact treatment and control groups are commonly performed in various educational, psychological, and biomedical studies. However, recruiting and retaining intact groups present various practical, financial, and logistical challenges to evaluators and often, cluster randomized trials…

The concept of direction dependence has attracted growing attention due to its potential to help decide which of two competing linear regression models (X ? Y or Y ? X) is more likely to reflect the correct causal flow. Several tests have been proposed to evaluate hypotheses compatible with direction dependence. In this issue, Thoemmes (2015)…

Participants included 483 undergraduate drinkers who were assessed on drinking motives and alcohol behaviors. Results indicated differences in coping drinking motives and alcohol-related negative consequences between first-generation college students (FGCS) and continuing generation college students (CGCS) status depended on sex. Implications for…

A latent variable modeling approach for scale reliability evaluation in heterogeneous populations is discussed. The method can be used for point and interval estimation of reliability of multicomponent measuring instruments in populations representing mixtures of an unknown number of latent classes or subpopulations. The procedure is helpful also…

Purpose: This study examined the interrelationships between a set of antecedent academic intrinsic motivations and metacognitive strategy such as goal orientation, perceived value and religiosity in Fundamental Knowledge for Matriculation courses (FKM). It also investigated the relationship between intrinsic motivation and metacognitive strategy…

Multivariate analysis of variance (MANOVA) is widely used in educational research to compare means on multiple dependent variables across groups. Researchers faced with the problem of missing data often use multiple imputation of values in place of the missing observations. This study compares the performance of 2 methods for combining p values in…

In education research, small samples are common because of financial limitations, logistical challenges, or exploratory studies. With small samples, statistical principles on which researchers rely do not hold, leading to trust issues with model estimates and possible replication issues when scaling up. Researchers are generally aware of such…

The purpose of this study was to investigate perspectives of Early Childhood Educators (ECEds) about inclusion of Children With Special Needs (CWSN) by examining their attitudes, training needs, and inclusive practices used in the inclusive classroom. One hundred twenty-eight ECEds completed a questionnaire that included the Scale of Teachers'…

This study explores how often students are engaged in their science classes and their affective states during these times, using an innovative methodology that records these experiences "in situ". Sampling a subset of high schools in the U.S. and Finland, we collected over 7,000 momentary responses from 344 students over the course of a…

Globally, decline in employment has affected the youth more compared to other cohorts with youth in developing countries being particularly hard hit. There have been various interventions by the Kenyan government to address the challenge of youth employment through human capital development like the Youth Enterprise Development Fund (YEFD).…

This research aimed to (1) design a curriculum on Production of Charcoal Briquettes from Agricultural Residues, (2) implement the designed curriculum, and (3) study and compare the learning achievements of Matthayomsuksa 3 students at Samakee Wittaya Municipality School in terms of knowledge, learning skills, and participation in the production of…
