I am tasked by my boss, as an investigator, from the community health department, to look into a surprising absence pattern in two middle schools where students got absent with the claim of sickness. I need to formulate hypotheses and questions to look in to the matter in an efficient manner. About these schools, relevant data is also significant; particularly all through the term the attendance of students in all classes, the calendar timetables with their happenings, in addition to the grounds put up for absence.
