C)simple random sampling
D)stratified random sampling

Question

Quizplus · Accepted Answer

Nonprobability sampling methods, such as quota and convenience sampling, are known for having lower external validity than probability sampling methods. Cluster sampling and stratified random sampling, although not perfect, still offer some level of external validity by ensuring a sample that is representative of the larger population. Simple random sampling, on the other hand, offers the highest level of external validity among probability sampling methods by ensuring that every individual in the population has an equal chance of being selected for the sample.
