A sociologist wanted to investigate high school students' attitudes towards environmental recycling initiatives within their schools. Previous research on student involvement yielded conflicting results. The sociologist randomly selected six secondary schools from a compiled list of all 42 secondary schools in the county. Five of the six schools agreed to participate. The sociologist then distributed a standardized survey to student council representatives in Year 9 and Year 12 across those five schools.
Explain how the sociologist could have selected the six schools using random sampling.
