Answer 2

Answer:

No, It is a Cluster Sampling.

Step-by-step explanation:

Simple Random Sampling is the sampling when samples are chosen randomly, where each unit has an equal chance of being selected in a sample.

If the population is divided into a different group called cluster and clusters are selected as a sample then it is Cluster Sampling.

Here, since Expert is interviewing all of the teachers at the selected schools, so it is Cluster Sampling, not a Simple Random Sampling.
