Secondary 3 Geography Quiz - Fieldwork: Answer Key

Total Marks: 40
Level: Secondary 3 | Topic: Fieldwork (syllabus-first practice, not exam-derived)


Section A: Answers (1 mark each)

  1. To collect primary data and observe geographical phenomena in the real world.
    Teaching note: Fieldwork connects classroom learning to actual places; it helps students test hypotheses.

  2. Survey responses / photographs / measured temperatures / observation notes. (any one)
    Teaching note: Primary data are gathered first-hand by the student during the study.

  3. Interview / mental map / photograph with notes. (any one)
    Teaching note: Qualitative data describe qualities and perceptions, not just numbers.

  4. A testable statement predicting a relationship between variables.
    Teaching note: E.g., "Pedestrian count is higher near train stations."

  5. Random sampling.
    Teaching note: Each person or site has equal chance; reduces bias.

  6. Median.
    Teaching note: Order data, the middle value is median; mean is average, mode is most frequent.

  7. Mental map.
    Teaching note: Mental maps show personal spatial perception, not exact scale.

  8. Wear bright clothing / stay on pavement / work in pairs. (any one)
    Teaching note: Safety is part of fieldwork planning.

  9. To test methods / find errors before real data collection.
    Teaching note: Pilot study improves reliability.

  10. Dividing population into groups then sampling from each group.
    Teaching note: Strata are based on traits like housing type; improves representation.


Section B: Answers (2 marks each)

  1. Convenience sampling selects whoever is easy to reach (1). Quota sampling sets amounts per group to match population (1).
    Teaching note: Convenience is fast but biased; quota improves representativeness.

  2. Any two: bar chart, line graph, table, pie chart (1 each).
    Teaching note: Visuals help compare counts across locations.

  3. Ask residents to rate attachment / list favourite places (1); use answers to map sense of place (1).
    Teaching note: Questionnaires can capture emotional and social links to place.

  4. Any two: informed consent, anonymity, no harm, respect privacy (1 each).
    Teaching note: Ethical fieldwork protects participants.

  5. Lay transect across both estates (1); count trees at intervals to compare (1).
    Teaching note: Transect shows spatial pattern; data test hypothesis.

  6. Gives past context / saves time / compares with own readings (1); e.g., confirms heat trend (1).
    Teaching note: Secondary data support primary findings.


Section C: Answers (3 marks each)

  1. Mean = (120+85+140+40) ÷ 4 = 385 ÷ 4 = 96.25 (2 marks: 1 for sum, 1 for division). Busiest: 17:00–18:00 (140) (1 mark).
    Teaching note: Mean is average; highest bar shows peak use.

  2. Difference at 12:00 = 34 − 30 = 4°C (2 marks: identify 34 and 30, 1; subtract, 1). Reason: car park has less vegetation and more heat-absorbing surfaces (1).
    Teaching note: Graph shows urban heat; surfaces like asphalt raise temperature.

  3. Primary issue: small sample (50) may not represent all visitors (1). Secondary issue: no comparison site or time pattern for litter (1); account lacks method detail (1).
    Teaching note: Good fieldwork needs clear sampling and controls.

  4. Map shows school is central to her daily life and mall is strongly linked (1). Limitation: mental maps are subjective, not to scale (1); may miss less familiar areas (1).
    Teaching note: Sense of place is personal; maps vary by experience.
