Identify the sampling procedure used in this situation. Sandra, a second year facilitator of the same school where Paula works,
is also assigned to look into the study habits of the second year level which
has 7 sections ranging from 43 to 45 students per section. But unlike Paula,
she asked the school registrar a copy of the 2nd year students' ranking from
highest to lowest grades. She then got the names of every 10th student on
the list and scheduled an interview for each selected student.​
