All values are weighted for the sampling weight, cluster weight and multi stage sampling.
Complex Sample Analysis procedure was considered so as to adjust for sample weight, and multi stage sampling.
We addressed this issue by using weighted analysis and complex sample analysis in SPSS to adjust for sample weight, and multi stage sampling.
All the analyses were performed using Complex Sample Analysis procedure which was deemed necessary to adjust for sample weight, and multi stage sampling [ 26].
In the survey, a multi-stage sample design was adopted.
Data from international comparative studies in education are generally derived from complex, multi-stage sample designs and rotated assessments.
The survey used an area-based clustered multi-stage sample design.
A body of literature explores challenges of clustered analysis across different levels of a multi-stage sample.
NHANES is a complex, stratified multi-stage sample designed to be representative of the US non-institutional population, implemented by the CDC's National Center for Health Statistics (NCHS).
A representative multi-stage sample of 2125 households from 60 enumeration areas distributed proportionally among four districts (Bondo, Busia, Siaya and Teso) was drawn for the survey using the frame of the 2008 KNBS.
In order to account for the stratified multi-stage sample design, the data were weighted to adjust for differential probability of selection within households as a function of household size and clustering of the data, and for differential non-response.
