How much attention do people pay to the disposal bins?
Scale from 1-10. 10 being the most dedicated you are to putting the right things into the right bins

10: 1 person
9-8: 11 people
7-4: 9 people
3-1: 0 :)

Interpretation:
We need to make it more clear for each item.
Compost Police?
Need more garbages on campus.
