Experiences Conducting Systematic Reviews from Novices' Perspective
Background: A systematic review (SR) is a sound methodology for collecting evidence on a research topic of interest and establishing the context of future research. Unlike ordinary or even expert literature reviews, SRs are systematic thus increasing the confidence in the findings from the previous published literature. SRs can be carried out by both experienced and novice researchers; however,...
متن کاملLinear Systematic Sampling
Linear systematic sampling design is very simple and operationally convenient in practice, but, when the population size is not a multiple of the sample size, results in a variable sample size and in this case sample mean as an estimator of the population mean is not unbiased. To overcome these difficulties and in some cases to increase the efficiency, a number of modifications of linear system...
متن کاملSystematic Sampling for Suspended Sediment
Because of high costs or complex logistics, scientific populations cannot be measured entirely and must be sampled. Accepted scientific practice holds that sample selection be based on statistical principles to assure objectivity when estimating totals and variances. Probability sampling--obtaining samples with known probabilities--is the only method that assures these results. However, probabi...
متن کاملSystematic Sampling in Image-Synthesis
In this paper we investigate systematic sampling in the imagesynthesis context. Systematic sampling has been widely used in stereology to improve the efficiency of different probes in experimental design. These designs are theoretically based on estimators of 1-dimensional and 2-dimensional integrals. For the particular case of the characteristic function, the variance of these estimators has b...
متن کاملAn overview of conducting systematic reviews with network meta-analysis
Introduction Systematic reviews with network meta-analysis (NMA) are published with increasing frequency in the health care literature. Prior to 2008, very few systematic reviews contained a NMA [1]; however, there has been a marked increase, to mid-2012 Lee recorded 201 published networks [2]. The statistical method has been available since 2002 [3,4] and owes its origins to much earlier work ...
