Cluster Sample
Definition
A cluster sample is a sampling method where the population is divided into groups or clusters, and a random selection of clusters is chosen to be included in the sample. All individuals within the selected clusters are then included in the sample.
Analogy
Imagine you're at a music festival with different stages. Instead of selecting individual people from each stage, you randomly choose a few stages and include everyone performing on those stages in your sample.
