Explain how you would carry out an observation to investigate the differences in territorial behavior (such as space-marking using personal items and physical distancing/seating choice) between highly crowded public transit environments (e.g., a rush-hour commuter train carriage) and uncrowded public transit environments (e.g., a mid-afternoon off-peak train carriage). Justify your decisions as part of your explanation.

You must refer to:

• structured or unstructured observations
• participant or non-participant observations
• time or event sampling
• collection of data.

You should use your own experience of carrying out an observation to inform your response.
