An understanding of statistical concepts is necessary for a chemist with a complete education. Here, statistical tests were taught using the R Commander and the Factoshiny packages. These packages run on R software and have a graphical user interface (GUI), which allows students to do statistical tests quickly and easily. These packages were…

Past research suggests revised parallel analysis (R-PA) tends to yield relatively accurate results in determining the number of factors in exploratory factor analysis. R-PA can be interpreted as a series of hypothesis tests. At each step in the series, a null hypothesis is tested that an additional factor accounts for zero common variance among…

Data collected from surveys can result in hundreds of variables and thousands of respondents. This implies that time and energy must be devoted to (a) carefully entering the data into a database, (b) running preliminary analyses to identify any problems (e.g., missing data, potential outliers), (c) checking the reliability and validity of the…

In this research, we explore how coworker ideation levels or, more specifically, the average ideation levels of coworkers within a workgroup affect a focal employee's ideation. We examine an underlying mechanism and a boundary condition of this influence process. Drawing on social cognitive theory, we argue that high coworker ideation levels are…

This article contains two measurement development studies on writing apprehension. Study 1 reexamines the validity of the writing apprehension measure based on the finding from prior research that a second false factor was embedded. The findings from Study 1 support the validity of a reduced measure with 6 items versus the original 20-item…

The definition of what it means to take a test online continues to evolve with the inclusion of a broader range of item types and a wide array of devices used by students to access test content. To assure the validity and reliability of test scores for all students, device comparability research should be conducted to evaluate the impact of…

Parallel analysis (PA) is a useful empirical tool for assessing the number of factors in exploratory factor analysis. On conceptual and empirical grounds, we argue for a revision to PA that makes it more consistent with hypothesis testing. Using Monte Carlo methods, we evaluated the relative accuracy of the revised PA (R-PA) and traditional PA…

The study developed and standardized an Inventory for measuring Students' Integration into University Academic Culture named Inventory for Students' Integration into University Academic Culture (ISIUAC). The increase in dropout rates, substance use, cultism and other deviant behaviours in Nigerian universities makes it necessary for one to ask the…

The higher education market in South Korea has matured over recent decades. Higher education institutions have invested in many areas to boost the student experience. Student satisfaction has been identified as a key variable in explaining the holistic evaluation of the course. This study aims to fulfil a void in research by developing a study…

Career paths are no longer linear or predictable due to the instability and dynamic changes occurring in the work environment. Career researchers have acknowledged this trend and emphasized the significance of individuals' actual behaviors in career development. Occupational engagement is an essential behavior that leads to successful and…

Motives behind occupational choice of graduates in two tertiary training programs for Israeli ultraorthodox (Haredi) women, practical engineering (PE) and teaching (T), are explored. Five hundred and twelve participants (278 PEs and 234 Ts) answered a questionnaire referring to 13 potential work motives. The main findings are as follows: (a)…

In order to extend previous research on procrastination as a cause of performance failure due to faulty self-regulation, we developed a model of self-regulated learning failure and tested it in two separate studies (N1 = 378, N2 = 315). The relationships between procrastination, disorganisation, the forethought phase of self-regulated learning…

Purpose: This was an investigation of the dimensionality of oral and written language to test the hypothesis that a two-factor model with sound/word and sentence/discourse language levels would best fit language and literacy data for a population-based sample in the school-age years. Method: A stratified secondary data set of 1,500 participants…

The aim of this study was to determine the variables that explain the anxiety towards mathematics in college students. For this purpose, we used the scale RMARS that integrate 25 items. The sample is non-probabilistic by convenience and the questionnaire was applied to 100 student's enrollment in the "Instituto Tecnológico de Veracruz"…

While a considerable number of studies have focused on factors driving employees to voluntarily participate in training programs, much less is known on this topic with regard to the unemployed population, in particular the older unemployed, who often are in a vulnerable labor market position due to educational deficits and skills obsolescence.…
