Sagot :
Probability and multistage sampling is a sampling technique in which researchers choose samples from a larger population using a method based on the theory of probability.
- Multistage sampling, also known as multistage cluster sampling, involves taking a sample from a population in successively smaller groupings. In national surveys, this technique is frequently employed to gather information from a sizable, geographically dispersed population.
- Multistage sampling is used in this Gallup poll. For instance, they might pick a predetermined number of area codes at random before sampling a predetermined number of phone numbers from each area code.
- The components from each stratum are present in the sample. In contrast, when using cluster sampling, the sample contains components from the sampled cluster. With multistage sampling, we choose a sample by combining various samples.
