A-Level Geography H1 Quiz - Fieldwork (Answer Key)

Section A: Research Design and Methodology

1. Stratified Sampling or Systematic Sampling.

   • Reason: Stratified ensures that different land-use types are represented at each distance interval; Systematic (e.g., every 500m) ensures an unbiased, objective spread across the urban gradient to identify a clear spatial pattern. (4 marks)

2. Definition: A survey where respondents rate a feature on a scale between two opposites (e.g., -3 Very Unsafe to +3 Very Safe).

   • Explanation: It quantifies subjective perceptions, allowing the researcher to calculate an average "score" for safety, which is easier to analyze statistically than open-ended comments. (4 marks)

3. Justification: A rain gauge only measures precipitation (input). A Double Ring Infiltrometer measures the actual rate at which water enters the soil (process).

   • Context: In a parking lot (impermeable), the infiltrometer will show near-zero rates, whereas in a park, it will show high rates, directly testing the research question on land-use influence. (5 marks)

4. Primary Data: Data collected first-hand by the researcher (e.g., field measurements of river depth, interviews with residents).

   • Secondary Data: Data collected by others (e.g., PUB flood maps, Meteorological Service rainfall records).
   • Context: Primary provides site-specific current data; secondary provides historical trends or large-scale context. (4 marks)

5. Implementation:

   • 1. Establish a baseline (start point) at the top of the slope.
   • 2. Use a measuring tape to mark intervals (e.g., every 10 meters).
   • 3. Take a soil moisture reading at exactly each marked interval regardless of surface variation. (4 marks)

6. Importance:

   • 1. Test the feasibility of the chosen methodology (e.g., are the questions too complex?).
   • 2. Identify potential hazards or access issues in the area.
   • 3. Refine the sampling strategy to ensure the data collected will actually answer the research question. (5 marks)

7. Comparison:

   • Questionnaires: Better for quantitative data, larger sample sizes, and easy statistical comparison. However, they lack depth.
   • Semi-structured Interviews: Allow for "probing" and detailed qualitative insights into why the elderly feel a certain way. Better for capturing nuance but time-consuming and harder to generalize. (6 marks)

Section B: Data Presentation and Analysis

8. Scatter Graph.

   • Justification: The research is looking for a correlation between two continuous numerical variables (rainfall and frequency). A scatter graph allows the researcher to identify if a positive, negative, or null relationship exists. (4 marks)

9. Proportional Symbol Map: Uses symbols of different sizes to represent the magnitude of a phenomenon at a specific point.

   • Choropleth Map: Uses shaded areas to show averages/densities across administrative boundaries.
   • Effectiveness: Flood hotspots are often point-specific (e.g., a specific clogged drain); a proportional symbol map highlights the exact location and intensity of the hotspot without being constrained by artificial boundary lines. (5 marks)

10. Indication: It indicates a weak or null correlation. This suggests that distance from the railway station is not the primary driver of land value in this specific area, or that other factors (e.g., proximity to schools, amenities) are more influential. (4 marks)

11. Analysis: A cross-section shows the vertical profile of the land. By comparing a "pre-development" profile with a "post-development" one, geographers can see how leveling land or building embankments has altered the natural flow of water and potentially increased flood risk in lower-lying areas. (5 marks)

12. Reasoning:

• Mean: Provides the average perception of liveability.
• Standard Deviation: Shows the spread of the data. A high SD indicates that residents have wildly different experiences (inequality in liveability), whereas the mode only shows the most common answer, ignoring the extremes. (6 marks)

13. Comparative Analysis: By comparing two contrasting sites, the researcher can isolate the variables that cause the difference. For example, if both sites have the same climate but different liveability scores, the researcher can conclude that human factors (planning, governance) are the primary drivers, not physical geography. (5 marks)

14. Process: Concrete is an impermeable surface. This prevents infiltration into the soil, significantly increasing surface runoff. This water reaches the river channel much faster (reduced lag time), leading to a higher and sharper peak discharge on the hydrograph. (6 marks)

Section C: Evaluation and Ethics

15. Evaluation: Low reliability.

    • Temporal Bias: Tuesday morning excludes the working population and students.
    • Sample Bias: The data will be skewed toward the perceptions of retirees or stay-at-home parents, who may perceive safety differently than those who navigate the area at night. (6 marks)

16. Minimization:

    • 1. Use designated paths to avoid soil compaction and trampling of rare flora.
    • 2. Use non-invasive equipment (e.g., avoiding digging deep holes) and ensure all equipment is removed after the study to prevent littering/pollution. (5 marks)

17. Evaluation:

    • Strengths: Provides a "macro" view of change over time (temporal analysis) and covers a larger area than a student can walk.
    • Limitations: Lacks the "ground-truth" detail (e.g., satellite images show a building, but not the quality of life inside).
    • Conclusion: Highly useful as a complementary tool to validate primary observations. (6 marks)

18. Ethics:

    • 1. Informed Consent: Ensuring residents understand the purpose of the study and agree to participate.
    • 2. Anonymity/Confidentiality: Protecting identities, especially in informal settlements where residents may fear eviction or legal repercussions.
    • 3. Sensitivity: Avoiding intrusive questions that might cause distress regarding poverty or trauma. (7 marks)

19. Discussion:

    • Agree (to some extent): For a student project, 20 is a manageable number and may provide a general "snapshot" of trends.
    • Disagree: Statistically, 20 is too small to be representative of a whole neighborhood. A few "outlier" opinions can heavily skew the results.
    • Conclusion: It is sufficient for a preliminary study but insufficient for drawing generalized conclusions about the entire population. (8 marks)

20. Evaluation: Low validity.

    • Selection Bias: The sample is "convenience sampling" and is clustered around a community center.
    • Spatial Bias: People living near a community center likely have higher liveability (better access to services) than those living on the periphery of the neighborhood.
    • Conclusion: The conclusion is a generalization based on a non-representative, privileged sample. (8 marks)
