Secondary 4 Geography Quiz - Fieldwork (Answer Key)
Total Marks: 40
Topic: Fieldwork (syllabus-first, Stage 4/5 generated; not claimed as past-year derived)
Section A: Answers 1–8
1. [1] To focus the investigation and guide what data to collect and analyse.
Teaching note: A research question defines the aim. Without it, fieldwork becomes unfocused. Common mistake: confusing research question with hypothesis (a testable statement).
2. [1] Primary data is collected first-hand by the student (e.g., survey); secondary data is collected by others (e.g., government report).
Teaching note: Distinguish source of data. Mark for any valid difference.
3. [1] Singapore Tourism Board annual visitor report / STB website statistics.
Teaching note: Accept any published source (e.g., NEA, SingStat). Must be pre-existing data not gathered by student.
4. [1] Random sampling.
Teaching note: Equal probability is key to random sampling.
5. [1] Dividing population into subgroups (strata) and sampling from each proportionally.
Teaching note: Used when population has clear categories (e.g., age, zone).
6. [1] Can collect views/opinions from many people efficiently.
Teaching note: Other valid: standardised, quantifiable.
7. [1] A line across the study area along which observations are made at intervals.
Teaching note: Transects show spatial change (e.g., beach to inland).
8. [1] Identifies confusing questions before real use / improves reliability.
Teaching note: Pilot test = small trial run.
Section B: Answers 9–15
9. [3] Method: Systematic sampling at every 50 m along the park coastline.
Marks: 1 for method name, 2 for explanation (covers space evenly, easy to repeat).
Teaching note: Systematic sampling is good for linear features like coastlines.
10. [2] Mean = (12 + 5 + 20 + 8) ÷ 4 = 45 ÷ 4 = 11.25 items.
Marks: 1 for sum, 1 for division and answer.
Teaching note: Mean = total ÷ count. Show working for mark.
11. [4] (1) Students draw familiar places showing attachment; (2) Size/Detail of drawn areas shows importance.
Marks: 2 per point with elaboration.
Teaching note: Mental maps reveal perception, not just physical layout.
12. [2] Provides numerical data that can be averaged / compared statistically.
Marks: 1 reason, 1 elaboration.
Teaching note: Likert scale turns opinion into ordinal data.
13. [3] Method: Count pedestrians every 100 m interval using tally counter.
Marks: 1 systematic, 1 interval, 1 tool.
Teaching note: Systematic = fixed interval, not random.
14. [3] Trend: Drop in 2020 (COVID), rise after, 2022 highest at 50k.
Marks: 1 describe drop, 1 recovery, 1 peak. Refer to chart values.
Teaching note: Use data from placeholder: 45→20→30→50.
15. [2] (1) Informed consent; (2) Anonymity.
Marks: 1 each.
Teaching note: Ethics protect respondents.
Section C: Answers 16–20
16. [5] Method: Use systematic or transect sampling at 10 m intervals from MRT; count litter in 5 m² quadrats; record distance; compare density.
Marks: 1 hypothesis link, 1 sampling, 1 quadrat, 1 distance measure, 1 analysis.
Teaching note: Must test stated relationship.
17. [3] Divide area into A/B/C strata; sample equally in each; compare coastal-inland change.
Marks: 1 strata, 1 equal sample, 1 purpose.
Teaching note: Map shows zones for stratification.
18. [2] Data type: Ordinal (categorical ordered). Limitation: vague "rarely" no frequency.
Marks: 1 type, 1 limitation.
Teaching note: Ordinal ≠ interval.
19. [3] Photos show green spaces, litter, infrastructure; e.g., photo of solar panels shows environmental effort.
Marks: 1 use, 2 example.
Teaching note: Visual evidence supports sustainability claims.
20. [4] Difference = 31 – 29 = 2°C. Shows ground warmer (urban heat / microclimate).
Marks: 1 calc, 1 value, 2 explanation.
Teaching note: 2 m warmer = surface heating; microclimate variation.
