All the 12 regions in the country were represented in the survey. From each region, 2 provinces were selected. All schools within each province were stratified into four namely, urban public, urban private, rural public, rural private. From each stratum, a random sample of secondary schools was selected. Within each sample school, classes were stratified according to year level. A random sample of classes was selected from each year level. A random sample of classes was selected from each year level. All students in the sample classes were included in the study. Given the above sampling design, determine the following: a. Target population b. Sampling population c. Stratification variables (identify all) d. Elementary unit e. Sampling frames needed to select the samples (identify all)
