Subject: Geography
Level: Secondary 3
Topic: Map, Graph, and Data Skills

---

Section A: Map Skills and Spatial Patterns

1. State the four-figure grid reference for the area containing the Primary School. [1]

• Answer: 1234 (Note: Accept any valid 4-figure GR based on the hypothetical map description, e.g., if the school was defined at 1234 in the prompt context. Since the prompt implies a hypothetical map, the specific number depends on the visual. For this key, we assume the school is at 1234 as per Q3 context clue).
• Marking: 1 mark for correct 4-figure grid reference.

2. Describe the location of the Community Park in relation to the River. [2]

• Answer: The Community Park is located to the North-West / West / East (depending on map orientation) of the River. It is situated on the opposite bank / same bank as the Residential Zone.
• Marking:
  • 1 mark for correct directional relationship (e.g., North of the river).
  • 1 mark for specific detail (e.g., adjacent to, separated by a road).

3. Calculate the straight-line distance in kilometres between Point A (Grid Ref 1234) and Point B (Grid Ref 1534). [2]

• Answer: 3 km.
• Working: Difference in Easting is 15 - 12 = 3 units. Northing is same (34). Each unit is 1 km. Therefore, 3 km.
• Marking:
  • 1 mark for correct calculation of grid difference.
  • 1 mark for correct unit (km).

4. Identify the dominant land use type found in the North-West quadrant of the map extract. [1]

• Answer: Residential / Housing / Industrial (Depending on hypothetical map). Let's assume Residential based on typical urban planning models in syllabus.
• Marking: 1 mark for correct identification.

5. Suggest one reason why the Industrial Zone is located downstream from the Residential Zone, based on environmental considerations. [2]

• Answer: To prevent industrial waste / polluted water from flowing towards the residential area / drinking water intake.
• Marking:
  • 1 mark for identifying pollution/waste risk.
  • 1 mark for linking direction of flow (downstream) to protection of residents.

Section B: Graphical Data Interpretation

6. State the month with the highest average temperature. [1]

• Answer: April / May (Assuming typical tropical pattern described). Let's say May.
• Marking: 1 mark for correct month.

7. Calculate the annual temperature range for City X. [2]

• Answer: 3°C (Example: Max 28°C - Min 25°C).
• Marking:
  • 1 mark for identifying max and min temperatures correctly from graph.
  • 1 mark for correct subtraction and unit (°C).

8. Describe the pattern of rainfall distribution throughout the year. [3]

• Answer: Rainfall is high throughout the year / There are two peak rainfall seasons (May and November). There is a relative dry period from June to August. Total annual rainfall is high (e.g., >2000mm).
• Marking:
  • 1 mark for general pattern (high year-round or bimodal).
  • 1 mark for identifying specific peaks/troughs.
  • 1 mark for using data values to support description.

9. Based on the data in Fig. 2, identify the likely climate type of City X. [1]

• Answer: Equatorial / Tropical Rainforest Climate.
• Marking: 1 mark for correct climate classification.

10. Explain how the rainfall pattern in Fig. 2 might influence the scheduling of outdoor tourism activities in City X. [2]

• Answer: Outdoor activities should be scheduled during the drier months (June-August) to avoid disruption. Activities in May/November should have indoor alternatives or be scheduled in the morning when rainfall might be lower (if convectional).
• Marking:
  • 1 mark for linking dry/wet seasons to activity scheduling.
  • 1 mark for specific example of adaptation (e.g., indoor backup).

Section C: Statistical Analysis of Fieldwork Data

11. Calculate the mean (average) pedestrian count for Area A across the five time intervals. [2]

• Answer: 117.
• Working: (45 + 120 + 180 + 150 + 90) / 5 = 585 / 5 = 117.
• Marking:
  • 1 mark for correct sum (585).
  • 1 mark for correct division by 5.

12. Identify the mode (most frequent value) for Area B. If there is no single mode, state 'No Mode'. [1]

• Answer: No Mode. (Values: 12, 15, 10, 25, 40 are all unique).
• Marking: 1 mark for "No Mode".

13. Describe the trend in pedestrian footfall for Area A from 09:00 to 17:00. [3]

• Answer: Footfall increases rapidly from 09:00 to 13:00, peaking at 13:00 (lunchtime). It then decreases steadily from 13:00 to 17:00 as the shopping day ends.
• Marking:
  • 1 mark for identifying the increase.
  • 1 mark for identifying the peak time.
  • 1 mark for identifying the subsequent decrease.

14. Compare the pedestrian activity in Area A and Area B at 13:00. Suggest one reason for the difference. [3]

• Answer: Area A has significantly higher footfall (180) compared to Area B (10). This is because Area A is a commercial shopping area where people gather for lunch and shopping during the day, whereas Area B is residential where people are likely at work or school.
• Marking:
  • 1 mark for correct comparison (A > B).
  • 1 mark for identifying land use difference (Commercial vs Residential).
  • 1 mark for explaining human behaviour (shopping/work).

15. The students used systematic sampling (counting every 10th person) for a separate survey on shopper satisfaction. State one advantage of using systematic sampling over convenience sampling in this context. [2]

• Answer: It reduces researcher bias because the selection of participants is based on a fixed interval rather than the researcher's choice. It provides a more representative sample of the population passing through.
• Marking:
  • 1 mark for identifying reduced bias / objectivity.
  • 1 mark for explaining representativeness.

Section D: Data Presentation and Evaluation

16. State the most appropriate graph type to compare the changes in footfall over time for both Area A and Area B simultaneously. [1]

• Answer: Dual Line Graph / Multiple Line Graph.
• Marking: 1 mark for correct graph type.

17. Explain why a pie chart would be unsuitable for presenting the data in Table 1. [2]

• Answer: Pie charts show parts of a whole (percentages) at a single point in time. Table 1 shows changes in data over a continuous period (time series), which requires a line or bar graph to show trends.
• Marking:
  • 1 mark for stating pie charts show proportions/static data.
  • 1 mark for stating the data is time-series/trend-based.

18. A student claims: "Area B is more economically important than Area A because it has higher pedestrian counts in the evening." Using evidence from Table 1, evaluate this claim. [3]

• Answer: The claim is incorrect. Even at 17:00 (evening), Area A (90) has higher footfall than Area B (40). Furthermore, Area A has much higher total footfall throughout the day, suggesting greater economic activity (shopping/spending). Area B is residential, so footfall is naturally lower and less indicative of direct economic transaction volume.
• Marking:
  • 1 mark for refuting the claim with data (90 > 40).
  • 1 mark for referencing total daily volume.
  • 1 mark for contextual understanding (residential vs commercial value).

19. A student measured noise levels: 60, 62, 58, 95, 61. (a) Identify the outlier in this data set. [1] * Answer: 95. * Marking: 1 mark. (b) Explain how this outlier might affect the calculation of the mean noise level. [2] * Answer: The outlier (95) is much higher than the other values. It will skew the mean upwards, making the average noise level appear higher than it typically is for the majority of the data points. * Marking: * 1 mark for stating it increases/skews the mean. * 1 mark for explaining it misrepresents the typical/central tendency.

20. When presenting fieldwork findings, why is it important to include both qualitative data (e.g., photographs, sketches) and quantitative data (e.g., graphs, tables)? [2]

• Answer: Quantitative data provides objective, measurable evidence (trends, magnitudes) that allows for statistical analysis. Qualitative data provides context, visual evidence, and human perspective that numbers alone cannot capture, leading to a more holistic and convincing conclusion.
• Marking:
  • 1 mark for benefit of quantitative (objectivity/measurement).
  • 1 mark for benefit of qualitative (context/depth/visual proof).
