The researcher divided the schools into different groups based on their characteristics, which is the basis of stratified sampling. Within each group, the researcher chose five schools, which could be chosen either randomly or systematically. However, since the stratification was done based on predetermined criteria, stratified sampling is the best choice. The researcher divided the population (schools) into four strata based on their characteristics (two-year state schools, four-year state schools, two-year private schools, and four-year private schools) and then selected a equal number of samples (five schools) from each stratum. This is known as stratified sampling.
