BACKGROUND There is paucity of information regarding time trends of weight status in children from rapidly developing economies like India. The aim of the study was to analyse the dynamics of growth and weight transitions in a cohort of school children from India. METHODS A population of 25 228 children was selected using stratified random sampling method from schools in a contiguous area in ...

The jugular foramen at the base of the skull varies in shape and size the foramen lies at the petrous part of temporal bone and behind by the occipital bone. It’s irregular in shape. Usually the right foramen is larger than the left. The variation in the foramen is observed in different racial group and sexes. The shape and size of foramen is inversely related to size of sigmoid sinus. Petrosal...

Synapses can only be morphologically identified by electron microscopy and this is often a very labor-intensive and time-consuming task. When quantitative estimates are required for pathways that contribute a small proportion of synapses to the neuropil, the problems of accurate sampling are particularly severe and the total time required may become prohibitive. Here we present a sampling method

In Experiment 1, subjects estimated {1) the mean of a random sample of 10 scores consisting of 9 unknown scores and 1 known score that was divergent from the population mean and {2} the mean of the 9 unknown scores. The modal answer {about 40% of the responses} for both sample means was the population mean. The results extend the work of Tversky and Kahneman {1971} by demonstrating that subject...

In the usual Bayesian approach to survey sampling the sampling design, plays a minimal role, at best. Although a close relationship between exchangeable prior distributions and simple random sampling has been noted; how to formally integrate simple random sampling into the Bayesian paradigm is not clear. Recently it has been argued that the sampling design can be thought of as part of a Bayesia...

The study was conducted to explore aggression in boys and girls as related to their academic achievement and residential background in Bangladesh. Stratified random sampling technique was used and total 80 respondents constituted the sample of the study. They were equally divided into boys and girls. Each group was again equally divided into high and low grade. Each subgroup was again equally d...

The study examines the impact of procedural justice, organizational commitment, job satisfaction on employee performance, and the potential mediating role played by organization citizenship behaviors in that process. This model was tested using a sample of 70 employees embedded in 2 groups from 15 branches of a large, syariah bank in Malang. The sample is taken using proportional random samplin...

The authors of this paper, statistics professors at Bryant University, recently had the opportunity to act as expert witnesses in a case involving the Internal Revenue Service (IRS) as the plaintiff. The IRS used some sampling techniques in selecting a random sample that did not appropriately represent the population at hand. This action led the IRS to draw inferences about the population that ...

BACKGROUND In 2009, three years after stopping mass treatment with azithromycin, a trachoma impact survey in four health districts in the Kayes region of Mali found a prevalence of trachomatous inflammation-follicular (TF) among children aged 1 to 9 years of >5% and a trachomatous trichiasis (TT) prevalence within the general population (≥1-year-old) of <1%. As a result, the government's nation...

It has been over 100 years since the classical paper published by Gosset in 1907, under the pseudonym "Student", demonstrated that yeast cells suspended in a fluid and measured by a haemocytometer conformed to a Poisson process. Similarly parasite eggs in a faecal suspension also conform to a Poisson process. Despite this there are common misconceptions how to analyse or interpret observations ...
