Theoretical Statistics
Cluster sampling is a statistical method where the population is divided into separate groups, known as clusters, and a random sample of these clusters is selected for analysis. This technique is especially useful when a population is too large or spread out to conduct a simple random sample. It connects to various aspects such as understanding how a sample represents a larger population, how sampling distributions are formed from these clusters, the implications of cluster size on sample size determination, and the specific method of executing cluster sampling effectively.
congrats on reading the definition of Cluster Sampling. now let's actually learn it.
