Fiona asked her team to suggest ways of surveying the population of their middle school to find out how many students use bottled water. Which student has the method that is most representative of the school’s population?

A representative survey should include students from across the school, rather than one particular class, seating row, or activity group. Asking every tenth student as they enter samples students from the whole school and is less likely to favor a group with something in common. Therefore, Amir’s method is the most representative.
