In systematic reviews, search precision is generally traded off against the desire to retrieve all relevant studies; however, there is no published evidence on typical precision values. The objective ...

ABSTRACT: Conflicting views had greeted the use of systematic sampling for sample selection and estimation in stratified sampling in terms of the precision of the population mean base on the inherent ...

We explore the aspects of sampling that are of highest importance in an analytical scheme. Devices and processes for obtaining appropriate samples outside of the laboratory are presented. There are ...

There are three aspects regarding samples that are of the highest importance in an analytical scheme: sample homogeneity (the distribution of an analyte in a matrix), the size distribution of the ...
