Because of the large sample size and systemic cluster sampling
, our study population is representative of pregnant women giving birth in Beijing hospitals.

design (9) and using the Fisher exact test.
Systematic adaptive cluster sampling
for the assessment of rare tree species in Nepal.
Totally, 106 participants were selected through cluster sampling
The bottom right panel shows one cluster around the area of lower probability, which would not be possible without both smart smoothing and adaptive cluster sampling
Design effect' is the factor taken for adjusting for heterogeneity of the population in cluster sampling
and to adjust the difference in precision between a simple random sample and a cluster sample was taken as 2.
Using the CASPER cluster sampling
methodology, a representative sample of 210 households in Burleigh County was selected to be interviewed.
A total of 480 Malaysian secondary school Form Four students sample was selected using Multistage Stratified Cluster Sampling
Stratified sampling is superior to simple random sampling in reducing sampling error and cluster sampling
is less costly, but these methods are not so popular because they are not too simple (Ding and Gao, 2008).
One example is adaptive cluster sampling
(ACS; Thompson, 1990; Thompson and Seber, 1996), which has been explored both in the field (e.
Among them are simple random sampling, stratified random sampling, systematic sampling cluster sampling
, two-stage cluster sampling
, and estimating the population size.
Firstly, cluster sampling
designs, where schools are selected in the first stage of sampling and individuals in the second, are often used in studies of young people, as schools facilitate access to the target population and survey administration (Carlin & Hocking, 1999; Heeringa, West & Berglund, 2010).
