Relevant households were randomly selected through stratified and multistage probability sampling.
The survey employed stratified multistage probability sampling units based on geographic area, gender, and age, which were determined based on the household registries of the 2005 National Census Registry, the most recent 5-year national census in Korea.
Data were weighted for the complex, multistage, probability sampling design.
The international sampling of TEDS-M followed a stratified multistage probability sampling design.
It uses a complex, multistage probability sampling design in order to select a sample representative of the civilian noninstitutionalized household population of the country.
Furthermore, the survey estimation procedure was used, since both datasets are not simple random samples but adopt a multistage probability sampling procedure.
Multistage probability sampling was used to select 831 households.
A stratified multistage probability sampling design was used.
Participants are selected through a multistage probability sampling design.
Participant enrollment employed a stratified, multistage, probability sampling design.
At each data collection site, participants were selected through a complex, multistage probability sampling design.
