Answer Key and Marking Scheme

Version: 1 of 5
Subject: Geography
Level: Secondary 3
Topic: Map, Graph, and Data Skills

Section A: Map Skills and Spatial Analysis

1. Give the 4-figure grid reference for the grid square containing the School.

  • Answer: 4681
  • Marking: [1] for correct 4-figure reference. (Accept 4681 only).

2. Give the 6-figure grid reference for the Hospital.

  • Answer: 475805
  • Marking: [1] for correct 6-figure reference. (Allow ±1 in the last digit for estimation errors, e.g., 474805 or 476805, but 475805 is precise based on prompt).

3. Calculate the straight-line distance in kilometres between the School (462815) and the Hospital (475805). Show your working.

  • Working:
    • Difference in Eastings: 47.5−46.2=1.347.5 - 46.2 = 1.3 grid units.
    • Difference in Northings: 81.5−80.5=1.081.5 - 80.5 = 1.0 grid units.
    • Using Pythagoras: 1.32+1.02=1.69+1.00=2.69≈1.64\sqrt{1.3^2 + 1.0^2} = \sqrt{1.69 + 1.00} = \sqrt{2.69} \approx 1.64 grid units.
    • Scale 1:25,000 means 1 grid unit (usually 1km or 4cm on map representing 1km) -> Correction: In standard 1:25,000 maps, 1 grid square is 1km x 1km.
    • Distance = 1.64 km.
  • Answer: Approx 1.6 – 1.7 km.
  • Marking: [1] for correct method/working, [1] for correct answer with units.

4. Describe the direction of flow of the river shown in the extract.

  • Answer: South-East (or SE).
  • Reasoning: Flows from 4582 (North-West) to 4780 (South-East).
  • Marking: [1] for correct compass direction.

5. Using the contour lines, describe the relief (shape of the land) in Grid Square 4582.

  • Answer: The land is steep/hilly. The contour lines are close together, indicating a rapid change in elevation.
  • Marking: [1] for identifying steep slope, [1] for linking to close contour lines.

Section B: Graph Interpretation and Construction

6. Calculate the annual range of temperature for City A.

  • Working: Max Temp (30°C in May) - Min Temp (26°C in Jan/Dec) = 4°C.
  • Answer: 4°C

7. Identify the wettest month and the driest month for City A.

  • Answer: Wettest: December (250mm); Driest: July (90mm).
  • Marking: [1] for wettest, [1] for driest.

8. Describe the overall pattern of rainfall distribution throughout the year for City A.

  • Answer: Rainfall is high throughout the year (no dry month below 90mm). There is a slight dip in the middle of the year (June/July) and higher rainfall at the beginning and end of the year. It shows a double maxima pattern or simply consistent high rainfall with seasonal variation.
  • Marking: [1] for noting high rainfall year-round, [1] for identifying the mid-year dip or end-year peak.

9. On the grid below, plot the rainfall data for January, June, and December.

  • Answer:
    • Jan: Bar height to 240mm.
    • Jun: Bar height to 100mm.
    • Dec: Bar height to 250mm.
  • Marking: [1] for each correct bar plotted accurately against the scale. Total [3].

10. Which energy source contributes the most to Country X’s energy mix?

  • Answer: Coal.
  • Marking: [1] for correct identification.

11. Calculate the angle (in degrees) required to represent Hydroelectric power on a pie chart.

  • Working: Hydroelectric is 15%.
    • Calculation: 15%×360∘=0.15×360=54∘15\% \times 360^\circ = 0.15 \times 360 = 54^\circ.
  • Answer: 54°
  • Marking: [1] for working, [1] for correct answer.

12. Suggest one advantage of increasing the share of Solar/Wind energy in Country X’s mix.

  • Answer: It is a renewable energy source / It produces no greenhouse gas emissions / It reduces dependence on fossil fuels.
  • Marking: [1] for any valid environmental or sustainability advantage.

Section C: Statistical Analysis and Data Presentation

13. Calculate the mean number of pedestrians for Location A.

  • Working: (120+115+125+110+130)/5=600/5=120(120 + 115 + 125 + 110 + 130) / 5 = 600 / 5 = 120.
  • Answer: 120
  • Marking: [1] for working, [1] for correct answer.

14. Determine the median number of pedestrians for Location C.

  • Data: 70, 75, 80, 85, 90 (Ordered).
  • Answer: 80
  • Marking: [1] for correct median.

15. Which location has the highest range of pedestrian counts? Show your working.

  • Working:
    • Location A: 130−110=20130 - 110 = 20
    • Location B: 50−30=2050 - 30 = 20
    • Location C: 90−70=2090 - 70 = 20
    • Correction for distinct answer in AI generation: Let's adjust Location B data in thought process to ensure a clear winner, but based on provided data:
    • Wait, the prompt data for B was 40, 45, 35, 50, 30. Range = 50−30=2050-30=20.
    • Prompt data for A: 130−110=20130-110=20.
    • Prompt data for C: 90−70=2090-70=20.
    • Self-Correction: The generated question data resulted in a tie. In a real exam, this would be flawed. For the purpose of the answer key, I will accept "All have the same range" or if the student identifies the tie.
    • Alternative Interpretation: If the question implies one must be highest, there is an error in the question design. However, strictly following the data:
    • Answer: All locations have the same range (20).
    • Marking: [1] for correct calculation of Range A, [1] for Range B, [1] for Range C and conclusion. (If student picks one incorrectly, 0 marks. If they state they are equal, full marks).

16. State one advantage of using a divided bar graph over a simple bar graph.

  • Answer: It allows for the comparison of the total magnitude and the internal composition (proportions) of different categories simultaneously.
  • Marking: [1] for mentioning composition/proportions within the total.

17. Which graph type would be most appropriate to show change over time?

  • Answer: B) Line Graph
  • Marking: [1] for correct selection.

Section D: Fieldwork Methods and Evaluation

18. Explain why stratified sampling might be more appropriate than random sampling for surveying different age groups.

  • Answer:
    • Stratified sampling ensures that specific sub-groups (strata) such as youth, adults, and elderly are represented in the sample in proportion to their presence in the population. [1]
    • Random sampling might accidentally miss out on a minority group (e.g., the elderly) if the sample size is small, leading to biased results. [1]
    • Therefore, stratified sampling provides a more representative and accurate view of the whole community's opinions. [1]
  • Marking: [3] for clear explanation of representation and bias reduction.

19. Explain one limitation of using personal opinion/bipolar surveys.

  • Answer:
    • Data is subjective; different people may interpret the scale differently (e.g., one person's "noisy" is another's "lively"). [1]
    • This reduces the reliability and comparability of the data collected by different students. [1]
  • Marking: [2] for identifying subjectivity and its impact on reliability.

20. "Secondary data is always more reliable than primary data." Do you agree? Justify your answer.

  • Answer:
    • Disagree. [1]
    • Justification for Primary Data: Primary data is collected specifically for the research question, ensuring relevance and control over methods. It is current and up-to-date. [1]
    • Justification for Secondary Data Limitations: Secondary data may be outdated, collected for a different purpose (bias), or the methodology may be unknown/unreliable. [1]
    • Nuance: However, secondary data from official sources (e.g., government census) can be highly reliable due to large sample sizes, whereas small-scale primary data may have sampling errors. Reliability depends on the source and method, not just the type. [1]
  • Marking: [4] for a balanced argument. 1 mark for stance, 2 marks for justification of both sides, 1 mark for final judgment/nuance.
