Quizplus · Accepted Answer

The RDD technique involves randomly generating telephone numbers using a computer program that selects them from all possible combinations of digits. This is an example of simple random sampling, where each individual has an equal chance of being selected. Systematic, stratified, and cluster sampling techniques rely on more deliberate methods of selecting individuals or groups, and double sampling involves a preliminary round of sampling to identify a subset of individuals for further study.
