Aim: To explore the lived experiences of female undergraduate nursing students about nursing as a profession and the circumstances that have influenced their experience. Introduction: Nursing as a profession is a relatively new practice, and thus in the developmental stage, in the UAE. The number of national students (Emirati) who enrol in the…

We present an equation, derived from standard statistical theory, that can be used to estimate sampling margin of error for student evaluations of teaching (SETs). We use the equation to examine the effect of sample size, response rates and sample variability on the estimated sampling margin of error, and present results in four tables that allow…

Various measures for identifying the onset of babbling have been proposed in the literature, but a formal definition of the exact procedure and a thorough validation of the sample size required for reliably establishing babbling onset is lacking. In this paper the reliability of five commonly used measures is assessed using a large longitudinal…

Job satisfaction is a major challenge among employees in many organizations. The purpose of this research project is to assess the effect of non-financial incentives on job satisfaction of teachers in public secondary schools of Kisii Sub County in the Republic of Kenya. The specific objectives for the study include: to assess the effect of…

This paper summarizes research associated with the development of the "Public Opinion Survey of Human Attributes-Stuttering" ("POSHA-S"), a survey instrument designed to provide a worldwide standard measure of public attitudes toward stuttering. Pilot studies with early experimental prototypes of the "POSHA-S" are summarized that relate to…

It is widely known that there is a dearth of education research in South Africa which takes as its methodological basis experimentation. The emphasis has been on educators' and learners' experiential understanding in the first decade of democracy after apartheid, when qualitative research predominated. The article investigates, first, the extent…

A sequential design utilizing identical samples was used to classify mixed methods studies via a two-dimensional model, wherein sampling designs were grouped according to the time orientation of each study's components and the relationship of the qualitative and quantitative samples. A quantitative analysis of 121 studies representing nine fields…

This paper empirically and systematically assessed the performance of bootstrap resampling procedure as it was applied to a regression model. Parameter estimates from Monte Carlo experiments (repeated sampling from population) and bootstrap experiments (repeated resampling from one original bootstrap sample) were generated and compared. Sample…

This study addressed statistical techniques that might ameliorate some of the sampling problems currently facing states with small populations participating in State National Assessment of Educational Progress (NAEP) assessments. The study explored how the application of finite population correction factors to the between-school component of…

The accuracy and variability of 4 cross-validation procedures and 18 formulas were compared concerning their ability to estimate the population multiple correlation and the validity of the sample regression equation in the population. The investigation included two types of regression, multiple and stepwise; three sample sizes, N = 30, 60, 120;…

This article considers various kinds of probability and non-probability samples in both experimental and survey studies. Throughout, how a sample is chosen is stressed. Size alone is not the determining consideration in sample selection. Good samples do not occur by accident; they are the result of a careful design. (Author/JAZ)

The 1988 National Survey of Postsecondary Faculty (NSOPF-88), later named the National Study of Postsecondary Faculty, was the first comprehensive study of higher education instructional faculty conducted by the National Center for Education Statistics since 1963. This report provides a description of the 1993 NSOPF and the data generated by its…

The sampling errors of maximum likelihood estimates of item-response theory parameters are studied in the case where both people and item parameters are estimated simultaneously. A check on the validity of the standard error formulas is carried out. The effect of varying sample size, test length, and the shape of the ability distribution is…

This manual provides guidance and documentation for users of the 1993 National Study of Postsecondary Faculty (NSOPF-93) restricted-use data files and of the public-use institution data file. The NSOPF-93 was the successor to a 1988 study of postsecondary faculty. Information about the purpose of the study, the data collection instruments, the…

This report summarizes the National Job Training Partnership Act (JTPA) Study, which examined the impact of Title IIA of JTPA on participants' employment, earnings, and welfare receipt. Between 1987 and 1989, more than 20,000 adults and out-of-school youths who applied for JTPA services in 16 areas across the country were randomly assigned to a…
