Section C: Statistical Analysis and Fieldwork Data (15 Marks)

A group of Secondary 3 students conducted fieldwork to investigate the quality of the environment in three different zones of a city: the CBD (Zone A), a Residential Area (Zone B), and an Industrial Estate (Zone C).

They used an Environmental Quality Survey (EQS) where they scored 5 criteria (noise, litter, greenery, traffic, building condition) from 1 (poor) to 5 (excellent). The maximum possible score is 25.

Table 1: Average EQS Scores

Zone	Location Type	Average EQS Score
A	CBD	18
B	Residential	22
C	Industrial	12

13. Which zone has the highest environmental quality according to the data?

<br> <br>

14. Calculate the mean (average) EQS score for all three zones combined. Show your working.
[2]

<br> <br> <br>

15. The students also counted the number of cars passing a specific point in each zone for 10 minutes.

• Zone A: 120 cars
• Zone B: 40 cars
• Zone C: 80 cars

Construct a bar chart to represent this data. (You do not need to draw the actual chart, but describe three essential features that must be included for the bar chart to be correct and clear.)
[3]

<br> <br> <br> <br>

16. Explain why random sampling might be difficult to achieve when conducting a pedestrian count in the CBD (Zone A).
[2]

<br> <br> <br>

17. The students noticed that their data for Zone C (Industrial) had a wide variation in scores (some spots were very clean, others very dirty). Explain how calculating the range of the data would help them understand this variation better than just using the mean.
[2]

<br> <br> <br>

18. Identify one potential source of human error in collecting the Environmental Quality Survey data.
[1]

<br> <br>

19. Suggest one way the students could improve the reliability of their EQS data.
[2]

<br> <br> <br>

20. Conclude: Based on Table 1, is there a clear relationship between land use and environmental quality in this investigation? Justify your answer using the data.

TuitionGoWhere Practice Paper - Geography Secondary 3

Answer Key and Marking Scheme (Version 2)

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

---

Section A: Map Skills and Spatial Analysis

1. Calculate the actual ground distance in kilometres between Point A and Point B.

• Working:
  • Map Distance = 4 cm
  • Scale = 1:25,000
  • Actual Distance (cm) = 4 cm × 25,000 = 100,000 cm
  • Convert to km: 100,000 ÷ 100,000 = 1 km
• Answer: 1 km
• Marks: [2] (1 mark for correct calculation/working, 1 mark for correct unit and value)

2. Describe the relief characteristics of the area surrounding Point B.

• Answer:
  • Point B is at a higher elevation (50m) compared to Point A (20m).
  • The contour lines are likely closer together near Point B if it is a slope, indicating steeper terrain, or it represents a hill/ridge. Given the elevation rise over a short distance, it is likely a slope or hill.
• Marks: [2] (1 mark for identifying higher elevation, 1 mark for inferring slope/steepness or hill feature)

3. Explain why Grid Ref 123456 (Point A) might be a more suitable location for a weather station than a steep slope near Point B.

• Answer:
  • Accessibility: Point A is at a lower elevation and likely flatter terrain, making it easier and safer for students to access regularly to read instruments.
  • Safety/Stability: Steep slopes (Point B) pose safety risks and may have unstable ground, making it difficult to secure equipment.
• Marks: [2] (1 mark for accessibility/flatness, 1 mark for safety/stability)

4. Define the term scale in the context of geographical maps.

• Answer: Scale is the ratio between the distance on the map and the corresponding actual distance on the ground.
• Marks: [1]

5. If the map scale was changed from 1:25,000 to 1:50,000, would the map show more or less detail? Explain.

• Answer:
  • It would show less detail.
  • Explanation: A 1:50,000 scale is a "smaller" scale (covers a larger area per unit of map space) compared to 1:25,000. Therefore, features must be generalized or omitted to fit the same map size, resulting in less detail.
• Marks: [3] (1 mark for "less detail", 2 marks for explanation linking scale ratio to area coverage/generalization)

Section B: Graph Interpretation and Climate Data

6. Calculate the annual temperature range for City X.

• Working:
  • Highest Temp: 29°C (Apr/May)
  • Lowest Temp: 27°C (Jan/Jul/Aug/Sep/Oct/Nov/Dec)
  • Range = 29 - 27 = 2°C
• Answer: 2°C
• Marks: [1]

7. Calculate the total annual rainfall for City X.

• Working:
  • Sum = 250+200+180+160+140+120+100+110+130+180+220+260
  • Sum = 2050 mm
• Answer: 2050 mm
• Marks: [2] (1 mark for working/attempt, 1 mark for correct answer)

8. Describe the rainfall pattern of City X throughout the year.

• Answer:
  • Rainfall is high throughout the year (no dry month below 100mm).
  • There is a slight dip in the middle of the year (June/July) with the lowest rainfall in July (100mm).
  • Rainfall peaks at the beginning and end of the year (Jan/Dec > 250mm).
  • Overall, it is evenly distributed but with a bimodal tendency or slight mid-year minimum.
• Marks: [4] (1 mark for "high year-round", 1 mark for identifying mid-year dip, 1 mark for identifying peaks, 1 mark for overall characterization e.g., "no distinct dry season")

9. Identify the likely climate type of City X and give one reason.

• Answer:
  • Type: Equatorial / Tropical Rainforest Climate.
  • Reason: High annual rainfall (>2000mm) and low annual temperature range (<2°C), with temperatures consistently high (>25°C).
• Marks: [2] (1 mark for correct climate type, 1 mark for valid reason linked to data)

10. Describe the trend in tourist arrivals between 2010 and 2019.

• Answer:
  • There was a steady/consistent increase in tourist arrivals.
  • Arrivals grew from 1 million to 5 million over the 9-year period.
• Marks: [2] (1 mark for direction of trend "increase", 1 mark for referencing data magnitude)

11. Suggest one possible geographical or global event that could explain the sharp drop in 2020.

• Answer:
  • The COVID-19 Pandemic / Global Health Crisis leading to travel restrictions.
• Marks: [1]

12. Explain why line graphs are suitable for displaying data over time.

• Answer:
  • Line graphs clearly show trends and changes over a continuous period.
  • They allow for easy visualization of increases, decreases, or fluctuations between data points.
• Marks: [2] (1 mark for mentioning trends/changes, 1 mark for continuity/visualization)

Section C: Statistical Analysis and Fieldwork Data

13. Which zone has the highest environmental quality?

• Answer: Zone B (Residential)
• Marks: [1]

14. Calculate the mean EQS score for all three zones combined.

• Working:
  • Sum of scores = 18 + 22 + 12 = 52
  • Number of zones = 3
  • Mean = 52 / 3 = 17.33
• Answer: 17.3 (or 17.33)
• Marks: [2] (1 mark for working, 1 mark for correct answer)

15. Describe three essential features for a correct bar chart.

• Answer:
  1. Title: A clear title describing the data (e.g., "Car Counts in Different Zones").
  2. Labels: Both x-axis (Zones) and y-axis (Number of Cars) must be labeled with units.
  3. Scale: The y-axis must have a consistent and appropriate numerical scale.
  • (Alternative: Bars must be of equal width and separated by gaps).
• Marks: [3] (1 mark per valid feature)

16. Explain why random sampling might be difficult in the CBD (Zone A).

• Answer:
  • The CBD has very high pedestrian traffic and congestion, making it physically difficult to stop people randomly or access certain spots safely.
  • Time constraints may force students to use convenience sampling (whoever is nearest) rather than true random selection.
• Marks: [2] (1 mark for identifying difficulty e.g., congestion/safety, 1 mark for linking to sampling method compromise)

17. Explain how calculating the range helps understand variation in Zone C.

• Answer:
  • The mean only gives the average, hiding extreme values.
  • The range (Highest Score - Lowest Score) shows the spread or disparity in environmental quality within the zone. A large range indicates inconsistency (some areas very good, some very bad), which the mean might mask.
• Marks: [2] (1 mark for defining range/spread, 1 mark for explaining why it reveals inconsistency/variation)

18. Identify one potential source of human error in collecting EQS data.

• Answer:
  • Subjectivity/Bias: Different students may interpret "litter" or "noise" differently (e.g., one student thinks 3 cars is noisy, another thinks it is quiet).
• Marks: [1]

19. Suggest one way to improve the reliability of the EQS data.

• Answer:
  • Repeat surveys: Conduct the survey at different times of the day or on different days and calculate an average.
  • Multiple observers: Have multiple students score the same location and average their scores to reduce individual bias.
• Marks: [2] (1 mark for strategy, 1 mark for explanation of how it improves reliability)

20. Conclude: Is there a clear relationship between land use and environmental quality? Justify.

• Answer:
  • Yes/Partially: There is a relationship.
  • Justification: The Residential zone (B) has the highest score (22), suggesting quieter, cleaner environments. The Industrial zone (C) has the lowest (12), likely due to pollution/litter. The CBD (A) is intermediate (18), possibly due to high maintenance but also high traffic. The data supports the hypothesis that land use influences environmental quality.
• Marks: [3] (1 mark for conclusion, 2 marks for justification using specific data comparisons from Table 1)
