This is an example of stratified sampling because the researcher has separated the population (teachers) into two strata (male and female) and then randomly selected respondents from each stratum. This ensures that both genders are represented in the sample and the results can be generalized to the population as a whole. The researcher is purposely selecting both male and female teachers, indicating a desire to have representation from both genders. This is an example of stratified sampling, as the population is divided into subgroups (male and female) and a random sample is taken from each subgroup.
