The finite population correction (FPC) factor is often used to adjust variance estimators for survey data sampled from a finite population without replacement. As a replicated resampling approach, the jackknife approach is usually implemented without the FPC factor incorporated in its variance estimates. A paradigm is proposed to compare the…

The purpose of the current study is to investigate the effects of frequency of peer victimization experiences on psychological and academic adjustment during early adolescence, with a focus on testing psychological adjustment as a mediator, as well as differences based on gender and type of victimization. The sample in this short-term longitudinal…

This research is a descriptive research with scanning method. It aims to define the relationship between the gender and academic success of secondary school students and their play preferences. The population of the research is composed of the secondary schools of Burdur city centrum and the sample group is composed of the students who are…

This research was carried out using the survey method in an attempt to find out the relationship between the life satisfaction and socio-economic status (SES) of adolescents. The research was conducted among 275 young Turkish people chosen by the random sampling method. The research findings determined that there was a significant difference…

Confidence intervals are an important tool to indicate uncertainty of estimates and to give an idea of probable values of an estimate if a different sample from the population was drawn or a different sample of measures was used. Standard symmetric confidence intervals for proportion estimates based on a normal approximation can yield bounds…

A multitude of methods has been proposed to estimate the sampling variance of ratio estimates in complex samples (Wolter, 1985). Hansen and Tepping (1985) studied some of those variance estimators and found that a high coefficient of variation (CV) of the denominator of a ratio estimate is indicative of a biased estimate of the standard error of a…

The objectives of this project were to construct two sets of balanced repeated replication (BRR) weights for two National Education Longitudinal Study of 1988 (NELS:88) sets of weights: one based on the third follow-up survey done in 1994 (NELS88:94); and the second based on the fourth follow-up survey done in 2000 (NELS88:2000). These weights are…

The National Assessment of Educational Progress (NAEP) measures the educational achievement of nationally representative samples of students in grades 4, 8, and 12. Local educational agencies tend to view the NAEP as a benchmark to which the educational achievement of their students can be compared. In particular, state departments of education…

This paper examines ways in which coherent reasoning about key concepts such as variability, sampling, data, and distribution can be developed as part of statistics education. Instructional activities that could support such reasoning were developed through design research conducted with students in grades 7 and 8. Results are reported from a…
