An environmental psychology student is conducting an observational study on recycling behaviour at a university campus. The campus has dual-bin stations (one bin for dry recyclables, one for general landfill waste).
Behaviour was recorded for individuals approaching the dual-bin stations with recyclable items. The student observed behaviour across six different recycling hubs (Hub 1 to Hub 6).
Table 1 shows the results of each observation.
| Recycling Hub | Arts Students | Science Students | ||
