Cluster sampling is the type of sampling used by the teacher for survey in order to select 5 classrooms of the school.
What is cluster sampling?
In order to conduct research, researchers split the population into several groups (called clusters) using the probability sampling approach of cluster sampling.
A population is divided into clusters, such as districts or schools, and some of these clusters are randomly chosen as your sample via the probability sampling technique known as cluster sampling. In a perfect world, each cluster would be a tiny reflection of the whole population.
It is given that he selected 5 classrooms of all the classes and did survey from all the students from it.
Instead of distributing the sample over the entire region, a cluster sample creates "pockets" of sampled units, which lowers the cost of collection operations. A list of all population units may not always be available, but a list of all clusters is frequently available or simple to create. This is another reason to use cluster sampling.
From the above information, it is quite clear that the sampling done by the teacher is cluster.
