The selection of the rice producers followed a multi-stage systematic random sampling technique.
However, in surveys involving complex multi-phase and multi-stage systematic sampling designs, the efficiency of ALS-based estimates is hampered by the ability of estimating the sampling variability correctly.
Participants (n = 1,595) were identified through stratified, multi-stage, systematic sampling.
This study employed a multi-stage systematic sampling procedure to recruit participants.
The study employed a multi-stage systematic sampling design to select participants in the severely affected areas of the earthquake.
This is a cross-sectional study, which employed a multi-stage systematic sampling procedure to recruit study participants.
In this study, we surveyed adult survivors in the earthquake-affected areas using a multi-stage systematic sampling design.
A population-based survey of 327 survivors (152 elders, 175 younger adults) was conducted in severely affected areas by the earthquake, using a multi-stage systematic sampling design.
Data were collected from adult South Australians in 2007 and 2008 (n = 5331) as part of a face-to-face, cross-sectional, whole-of-population, multi-stage, systematic area sampling population health survey.
A multi-stage, systematic area sampling method is used; annual survey results are standardised against weighted population-based norms to accommodate random imbalances in sampling.
HOS is a multi-stage, systematic, clustered area sample of households conducted face-to-face annually in spring based on the Australian Bureau of Statistics ABSS) collector districts (CDs).
