ASimple random sampling
BStratified random sampling ✓ Correct
CCluster random sampling
DSystematic random sampling
Correct answer: (B) Stratified random sampling — This technique is stratified random sampling, so the answer is stratified random sampling.
Explanation
★This technique is stratified random sampling, so the answer is stratified random sampling.
★In stratified sampling the population is first divided into groups called strata.
★Each stratum contains units with similar characteristics.
★A simple random sample is then drawn separately from each stratum.
★These samples are combined to form the overall sample.
★So sampling randomly from categories is stratified random sampling.
★So the answer is stratified random sampling.
