Section C: Applied Data Skills (Questions 15–20) [18 marks]

15. A fieldwork group wants to survey pedestrian flow. Location X is a busy MRT station; Location Y is a quiet park. Which is more suitable? Justify. [2]

16. Explain how a congestion pricing strategy can help reduce traffic congestion in a city. [3]

17. Study Fig. 4, a table of rainfall (mm) over 5 months. Calculate the mean monthly rainfall. Show working. [3]

Image pending generation: table for Q17.

18. Using the same table, in which month was rainfall lowest? What might this indicate about the season? [2]

19. Describe how you would present the rainfall data in a graphical form and why. [3]

20. A student concludes: "Higher population always means more water shortage." Using the data skills from this paper, explain why this may be too simple. [5]

SA2 Practice Paper Answers — Map Graph Data Skills (Version 1)

Total Marks: 60

Section A: Map Reading (21 marks)

1. [1] 0302
Teaching note: Read easting (horizontal, left-to-right) first: school is between 03 and 04 → 03. Then northing (vertical, bottom-to-top): between 02 and 03 → 02. Four-figure grid reference = 0302.
Common mistake: Writing northing first (0203).

2. [1] 0504
Teaching note: Hospital is in square easting 05–06, northing 04–05 → 0504.

3. [2]

• Mark 1: The easting is given as 02 but should be 03 (school is in easting 03–04).
• Mark 2: The northing is given as 03 but should be 02 (school is in northing 02–03).
  Teaching note: Grid reference always Easting-Northing. Student reversed or misread both.

4. [2] 032022 (or 031021 approx.)
Teaching note: Six-figure: take four-figure 0302, then estimate tenths within square. If school is central, easting +0.5→03 5? Actually six-figure splits each square into 10. Example: 0302 with school at half → 035025? For Sec 2, simple estimate: 032022 means 03 + 2/10 east, 02 + 2/10 north. Accept any reasonable tenth estimate.
Marking: 1 for correct four-figure base, 1 for plausible tenth.

5. [2] Human: school/hospital; Physical: river. [1+1]
Teaching note: Human features are built by people; physical are natural.

6. [3]
Working: School at (3,2), Hospital at (5,4).
Distance = √[(5−3)² + (4−2)²] = √[4+4] = √8 ≈ 2.83 km.
Or grid squares: 2 E, 2 N → diagonal ≈ 2.83 km.
Marks: 1 for correct coordinates used, 1 for method, 1 for answer with unit.

7. [2] River is to the west (or west-northwest) of school.
Teaching note: River along easting 02, school at 03 → river is west. 1 mark direction, 1 mark reference to map.

Section B: Graph & Data Interpretation (21 marks)

8. [3]

• Overall increase from 3.7m (2010) to 5.2m (2020). [1]
• Steady rise every 2 years by ~0.3m. [1]
• More than 40% growth (refer to figures). [1]
  Teaching note: Trend description must cite stats.

9. [3]
% increase = (5.2 − 3.7)/3.7 × 100 = 1.5/3.7 × 100 ≈ 40.5%
Marks: 1 formula, 1 subtraction, 1 final %.
Answer: 40.5%

10. [1] Domestic (800 m³)

11. [3]

• Domestic highest at 800 m³ (40% of total). [1]
• Industrial next at 500 m³. [1]
• Agricultural and Recreational low (<250 each). [1]
  Teaching note: Describe distribution = compare categories with values.

12. [2]

• Dense self-built wooden structures. [1]
• Stilt supports over ground/narrow paths. [1]

13. [3]

• No proper sanitation → disease spread. [1]
• Stagnant water under stilts → mosquitoes. [1]
• Overcrowding → poor air, fire risk. [1]
  Teaching note: Link physical feature to health outcome.

14. [2] 45%

Section C: Applied Data Skills (18 marks)

15. [2] Location X (MRT) more suitable [1] because higher pedestrian flow gives representative data [1].

16. [3]

• Charge vehicles entering congested zone. [1]
• Drivers reduce trips or shift time. [1]
• Less traffic, smoother flow. [1]

17. [3]
Mean = (120+90+150+80+110)/5 = 550/5 = 110 mm.
Marks: 1 sum, 1 divide, 1 answer.

18. [2] April (80 mm) [1]; likely drier season [1].

19. [3]

• Use bar chart [1]
• Months on x, rainfall on y [1]
• Easy comparison of values [1].

20. [5]

• Population is one factor but not only. [1]
• Water management (e.g., Singapore taps) offsets demand. [1]
• Climate/rainfall variability matters. [1]
• Data from Q8–Q17 shows usage type & infrastructure key. [1]
• Conclusion too simplistic without considering technology & distribution. [1]
