A group of students wishes to investigate the impact of land use on infiltration rates in an urban park. Suggest one appropriate primary data collection method they could use. [2]
\ -
Explain one advantage of using systematic sampling over random sampling when measuring river velocity along a profile. [4]
\ -
A research team is comparing the liveability of two different residential estates in Singapore. Why is it important to use a 'comparative' approach rather than studying a single site? [4]

Identify two potential sources of sampling bias when conducting pedestrian interviews in a city centre during a weekday. [4]
\ -
Distinguish between quantitative and qualitative data, providing one fieldwork example for each. [4]
\ -
A group of 18-year-old students is investigating urban fear in a specific neighbourhood. Justify the use of a bipolar perception survey for this study. [6]

-
State two safety precautions a student must take when collecting water quality samples from a fast-flowing stream. [2]
\ -
When measuring the depth of a river channel, why should measurements be taken at multiple points across a cross-section? [4]
\ -
Explain how the use of a 'decibel meter' provides more reliable data than a 'subjective noise rating' in an urban liveability study. [4]
\ -
A student records the number of people using a public plaza at 8am, 12pm, and 6pm. What type of sampling is being used, and why is it appropriate for this research? [6]
\ -
Describe one way a researcher can ensure the reliability of data when using a questionnaire to assess resident satisfaction in a favela. [6]
\ -
Explain the purpose of a 'pilot study' before conducting a full-scale fieldwork investigation. [6]

A student uses a map to select sites for infiltration tests. Explain how 'stratified sampling' would improve the representation of different land-use types. [8]
\
Section C: Evaluation and Synthesis (Questions 15-20)
-
Evaluate the usefulness of using photographs as a primary data source when investigating the physical characteristics of an informal settlement. [8]
\ -
"Fieldwork data is always subject to human error." To what extent do you agree with this statement in the context of measuring river discharge? [8]
\ -
Explain how a researcher would minimise the environmental impact of an investigation into soil erosion on a steep slope. [8]
\ -
Compare the effectiveness of structured interviews versus open-ended questionnaires in understanding the social needs of the elderly in an urban neighbourhood. [8]
\ -
A group of students concludes that "increased vegetation always leads to higher infiltration rates" based on three sites. Evaluate the validity of this conclusion. [10]
\ -
Discuss the challenges of conducting fieldwork in a high-density urban environment compared to a rural physical environment. [10]

Answers
A-Level Geography H1 Quiz - Fieldwork (Answer Key)
Section A: Research Design and Methodology
- Definition: The method used to select a representative subset of a population or area for study to make inferences about the whole. [2]
- Method: Infiltrometer / Double-ring infiltrometer. [2]
- Advantage: Ensures data is collected at regular intervals, allowing for the identification of a clear spatial trend/pattern along the river profile. [4]
- Comparative Approach: Allows the researcher to identify differences and similarities, isolating variables that contribute to liveability (e.g., comparing a planned estate vs. an unplanned one). [4]
- Bias: 1) Time bias (only capturing workers/commuters, missing students/homemakers); 2) Location bias (only capturing people at specific entrances/shops). [4]
- Distinction: Quantitative is numerical/measurable (e.g., temperature readings); Qualitative is descriptive/conceptual (e.g., interview transcripts on feelings of safety). [4]
- Justification: Bipolar surveys (e.g., -3 to +3) allow respondents to quantify subjective feelings of fear/safety, making qualitative perceptions easier to analyze statistically while still capturing the intensity of the emotion. [6]
Section B: Data Collection and Analysis
- Precautions: 1) Wearing high-visibility gear/life jackets; 2) Working in pairs/groups (buddy system). [2]
- Multiple Points: To account for the irregular shape of the river bed and ensure the average depth is representative of the entire cross-section. [4]
- Reliability: Decibel meters provide an objective, standardized numerical value (dB) that is not influenced by the observer's personal sensitivity to noise. [4]
- Sampling: Temporal sampling. Appropriate because urban land use (plazas) fluctuates significantly throughout the day based on human activity cycles (work/lunch/leisure). [6]
- Reliability: Using a standardized set of questions (structured) to ensure consistency across all respondents, or using a large enough sample size to reduce the impact of outliers. [6]
- Pilot Study: To test the feasibility of the methodology, identify flaws in the questionnaire, check the timing of the route, and ensure equipment works correctly before the actual data collection. [6]
- Stratified Sampling: The researcher divides the area into "strata" (e.g., concrete, grass, shrubbery) and samples proportionally from each. This ensures that rare but important land-use types are not missed, providing a more accurate overall average of infiltration. [8]
Section C: Evaluation and Synthesis
- Evaluation:
- Strengths: Provides visual evidence of overcrowding, building materials, and lack of infrastructure; permanent record for temporal comparison.
- Weaknesses: Only captures surface appearance; cannot show social dynamics or internal living conditions; subject to photographer's bias (framing). [8]
- Extent:
- Agree: Parallax error when reading gauges, inaccuracies in measuring river width, human error in timing floats.
- Counter: Use of digital flow meters reduces human error; repeated measurements (averaging) mitigate individual mistakes. [8]
- Minimising Impact: Avoiding trampling of vegetation by staying on designated paths; using non-invasive sampling tools; ensuring all equipment is removed; limiting the number of students at a single site. [8]
- Comparison:
- Structured Interviews: Better for probing deeper into "why" the elderly feel a certain way; allows for clarification.
- Open-ended Questionnaires: Better for gathering a wider range of unfiltered opinions from a larger sample, but may suffer from incomplete responses. [8]
- Validity:
- Low Validity: Sample size (3 sites) is too small to be statistically significant.
- Oversimplification: Ignores other variables like soil type, slope gradient, or soil compaction.
- Conclusion: The conclusion is a generalization and lacks sufficient evidence to be a geographical law. [10]
- Challenges:
- Urban: High human interference, noise pollution, ethical issues with privacy/consent, traffic hazards.
- Rural: Physical accessibility, weather extremes, lack of infrastructure, potential for wildlife/terrain hazards.
- Synthesis: Urban challenges are primarily social/ethical; rural challenges are primarily physical/logistical. [10]
