Identify the kind of sample that is described?

A researcher asked a simple random sample of 20 home-schooled children, a simple random sample of 20 children who attend private school, and a simple random sample of 20 children who attend public school their opinion on the new town curfew.

Stratified Sample

Step-by-step explanation:

Stratified sampling is done by making a homogeneous strata and selecting a simple random sample from each strata in such a way that heterogeneous population is divided into homogeneous strata.

In the statement children schooling divided into three strata that are home-schooled children, private school children and public school children. Then the random sample of 20 children are selected from each strata to ask about their opinion on the new town curfew. Here the population of children who attend school are divided into three strata and from each strata the random sample of 20 children is selected. So, this is an example of stratified sampling.
