A decision you can investigate
- You expect pedestrian counts to decline away from a shopping centre.
- A useful fieldwork 实地调查 design can test the pattern without claiming every street behaves alike.
Build the explanation
- Choose a focused question, justified sites, repeated timings and a consistent counting method.
- Systematic sampling 抽样 offers a clear interval; stratified sampling can represent contrasting zones.
Match the terms to their precise meanings.

Use these definitions in the particular context of Geographic inquiry and sampling.
Work through the evidence
- Count at five measured distances using the same five-minute interval at comparable times. Plot distance against count and examine exceptions.
- Note weather, junctions and events as competing explanations; keep original records and location evidence.
Why repeat counts at comparable times?

Fieldwork is a supervised inquiry and written report, not a fabricated dataset or desk-only exam. The case does not support that over-reading. The lesson states a limit on this case.
This one Geographic inquiry and sampling case settles the question for every setting.

Teacher approves access and safety; a correlation does not prove distance alone caused the pattern.
Test the limits
- Fieldwork is a supervised inquiry and written report, not a fabricated dataset or desk-only exam.
- Teacher approves access and safety; a correlation does not prove distance alone caused the pattern.

The concept and worked evidence support these claims; the stated limits rule out the universal shortcut.
Apply and explain your answer
- Why repeat counts at comparable times?
- To reduce the risk that timing rather than location explains the observed differences.
Use the terms precisely
- fieldwork: Collection of geographic evidence in the setting studied.
- sampling: Selecting observations from a wider population or area.

Write from a new count
- Counts at 0, 100, 200, 300 and 400 metres from a market, in the same five-minute slot, are 40, 28, 30, 15 and 9 people. A fair was at 200 metres that day.
- Say what the counts suggest and why the fair is a competing explanation. Do not claim distance alone caused the pattern.
Counts at 0, 100, 200, 300 and 400 metres from a market, in the same five-minute slot, are 40, 28, 30, 15 and 9 people. A fair was at 200 metres that day. What do the counts suggest, and why is the fair a competing explanation? Do not claim distance alone caused the pattern.
A correlation is not a single cause. The fair is another possible explanation, and repeated times reduce a timing confound.
Why not count at noon on one day and at dusk on the next, if you want to study distance?

The lesson repeats counts at comparable times so that the clock is less able to explain the pattern.
