This study examines the efficiency of EPI cluster sampling in assessing the prevalence of diarrhoea and dysentery. A computer was used to simulate fieldwork carried out by a survey taker. The bias and variance of prevalence estimates obtained using EPI cluster sampling were compared with those obtained using simple random sampling and cluster (stratified random) sampling. Efficiency ratios, cal...

The employed convergent research design under mixed methods approach. target population consisted 27 universities, which offer Bachelor education degree Tanzania mainland, 51,489 students, 708 lecturers, Chief officers and Directors quality...

In this research, the covariance estimates were used to estimate population mean in stratified random sampling and combined regression estimates. compared by employing robust variance-covariance matrices with traditional when estimating parameter, through two efficiency criteria (RE) squared error (MSE). We found that significantly improved quality of reducing effect outliers using (MCD, MVE) p...

This study assesses the effectiveness of stratification, based on photo-interpreted forest types, for strategic inventory. It uses results (from stratified sampling) for Total Merchantable Volume (TMV) in 18 Inventory Areas in Tasmanian State forest. The variance of the TMV as determined from stratified sampling is compared with the estimated variance of a simple random sample using the same nu...
