Answers
O-Level Geography Quiz - Fieldwork: Answer Key and Marking Scheme
Total Marks: 50
Section A: Geographical Inquiry Fundamentals (10 marks)
1. State the difference between a hypothesis and a research question in geographical inquiry. [2 marks]
Answer:
- A hypothesis is a specific, testable statement that predicts a relationship between two or more variables (e.g., "Air quality decreases as distance from an industrial estate decreases"). [1 mark]
- A research question is a broader question that guides the investigation and identifies what the study aims to find out (e.g., "How does proximity to an industrial estate affect air quality?"). [1 mark]
Marking notes:
- Award 1 mark for correctly defining/describing a hypothesis as a testable prediction.
- Award 1 mark for correctly defining/describing a research question as a guiding question.
- Accept any reasonable distinction that captures the predictive vs. exploratory nature.
2. Identify two primary data collection methods commonly used in geographical fieldwork. [2 marks]
Answer (any two of the following or other valid methods):
- Questionnaire/Survey
- Observation/Land use survey
- Interview
- Measurement (e.g., using instruments like anemometer, thermometer, decibel meter)
- Pedestrian/Vehicle count
- Environmental quality assessment
- Photograph/Sketch mapping
Marking notes:
- Award 1 mark for each correctly identified primary data collection method (max 2 marks).
- Do not accept secondary data collection methods (e.g., census data, online research).
3. A group of students is investigating the relationship between distance from a park and residents' sense of community. Suggest a suitable hypothesis for this investigation. [2 marks]
Answer (example): "The closer residents live to a park, the stronger their sense of community." OR "Residents living within 500 metres of a park have a higher sense of community than those living more than 500 metres away."
Marking notes:
- Award 1 mark for a clear, testable statement.
- Award 1 mark for specifying the relationship between the two variables (distance from park and sense of community).
- Accept any reasonable hypothesis that predicts a relationship between the two variables.
4. Explain why it is important to conduct a pilot study before carrying out the main data collection in geographical fieldwork. [2 marks]
Answer: A pilot study is important because:
- It allows researchers to test and refine data collection instruments (e.g., questionnaires, survey sheets) to ensure questions are clear and unambiguous. [1 mark]
- It helps identify potential problems with the methodology (e.g., timing, location access, sampling strategy) so adjustments can be made before the main data collection, improving the reliability and validity of the final results. [1 mark]
Marking notes:
- Award 1 mark for identifying the purpose of testing/refining instruments.
- Award 1 mark for explaining how it improves reliability/validity or helps identify problems.
- Accept any two valid reasons with explanation.
5. State one advantage and one disadvantage of using a questionnaire as a data collection method in fieldwork. [2 marks]
Answer: Advantage (any one):
- Can collect data from a large number of respondents quickly and efficiently.
- Standardised questions allow for easy comparison and statistical analysis.
- Can gather information on opinions, perceptions, and behaviours that cannot be directly observed.
- Relatively low cost compared to other methods like interviews.
Disadvantage (any one):
- Responses may be inaccurate if respondents do not understand questions or provide socially desirable answers (response bias).
- Low response rates can affect the representativeness of the sample.
- Closed-ended questions may limit the depth of responses.
- Cannot clarify ambiguous responses after the questionnaire is completed.
Marking notes:
- Award 1 mark for a valid advantage with brief explanation.
- Award 1 mark for a valid disadvantage with brief explanation.
Section B: Data Collection and Methodology (14 marks)
6. (a) Using the data in Table 1, calculate the total environmental quality score for each neighbourhood. [3 marks]
Answer:
- Neighbourhood A: +1 + 0 + 2 + 1 + 2 = +6 [1 mark]
- Neighbourhood B: -1 + (-2) + 1 + 0 + (-1) = -3 [1 mark]
- Neighbourhood C: +2 + 1 + (-1) + 1 + 0 = +3 [1 mark]
Marking notes:
- Award 1 mark for each correct total.
- Accept minor arithmetic errors if method is clearly shown (award partial marks at discretion).
(b) Based on your calculations, identify which neighbourhood has the highest environmental quality. Support your answer with reference to specific indicators. [2 marks]
Answer: Neighbourhood A has the highest environmental quality with a total score of +6. [1 mark] It scored positively on all indicators, with particularly high scores for green spaces (+2) and building maintenance (+2), and no negative scores on any indicator. [1 mark]
Marking notes:
- Award 1 mark for correctly identifying Neighbourhood A.
- Award 1 mark for supporting the answer with reference to specific indicators or explaining why it scored highest.
7. The students collected data on pedestrian traffic at three locations within a neighbourhood at different times of the day. Suggest how the pedestrian traffic data at the three locations could be shown on one graph to allow for comparison. [3 marks]
Answer: A multiple line graph or compound line graph could be used. [1 mark] The x-axis would represent time of day, and the y-axis would represent pedestrian count. [1 mark] Each location would be represented by a different coloured or patterned line, with a legend to identify each location. This allows for easy visual comparison of pedestrian traffic patterns across the three locations over time. [1 mark]
Marking notes:
- Award 1 mark for suggesting an appropriate graph type (line graph, multiple/compound line graph).
- Award 1 mark for describing axes (time on x-axis, pedestrian count on y-axis).
- Award 1 mark for explaining how the three locations would be differentiated (different lines, legend) and why this allows comparison.
- Accept bar chart if justified (e.g., grouped bar chart for discrete time periods).
8. A fieldwork group used systematic sampling to select every 5th household along a street for a questionnaire survey about recycling habits. Explain one strength and one limitation of using systematic sampling in this context. [4 marks]
Answer: Strength (any one, 2 marks):
- Systematic sampling is simple and quick to implement, as the researcher only needs to select households at a fixed interval, reducing the time needed for sample selection. [1 mark] This is practical for a street with many households and ensures even coverage along the entire street. [1 mark]
- It provides a more evenly spread sample across the study area compared to simple random sampling, reducing the risk of clustering. [1 mark] This ensures that households from different parts of the street are represented. [1 mark]
Limitation (any one, 2 marks):
- If there is an underlying pattern or periodicity in the street (e.g., every 5th house is a corner unit with different characteristics), the sample may be biased. [1 mark] This could lead to over- or under-representation of certain household types, affecting the representativeness of the findings. [1 mark]
- The starting point may introduce bias if not randomly selected. [1 mark] If the first household chosen is not representative, the entire sample may be skewed. [1 mark]
Marking notes:
- Award up to 2 marks for a well-explained strength (1 mark for identification, 1 mark for explanation/elaboration).
- Award up to 2 marks for a well-explained limitation (1 mark for identification, 1 mark for explanation/elaboration).
9. Identify an instrument, other than a thermometer, that could be used to measure an aspect of microclimate during fieldwork. State what the instrument measures. [2 marks]
Answer (any valid instrument and measurement):
- Instrument: Anemometer [1 mark]
- What it measures: Wind speed [1 mark]
- Other acceptable answers: Hygrometer (humidity), barometer (atmospheric pressure), lux meter (light intensity), decibel meter (noise level).
Marking notes:
- Award 1 mark for correctly naming an appropriate instrument.
- Award 1 mark for correctly stating what it measures.
10. Explain why it is important to consider the timing of data collection when conducting a pedestrian count survey. [2 marks]
Answer: Timing is important because pedestrian traffic varies significantly throughout the day (e.g., peak hours vs. off-peak hours) and on different days (e.g., weekdays vs. weekends). [1 mark] If data is collected only at one time, it may not be representative of typical pedestrian patterns, leading to inaccurate conclusions. Collecting data at multiple times or standardising the time ensures more reliable and comparable results. [1 mark]
Marking notes:
- Award 1 mark for identifying that pedestrian traffic varies with time.
- Award 1 mark for explaining how this affects reliability/representativeness or comparability.
Section C: Data Presentation and Analysis (12 marks)
11. (a) Describe the pattern of pedestrian traffic shown in Figure 1. [2 marks]
Answer: The MRT Station Exit has the highest pedestrian count (342), followed by the Bus Interchange (287), then the Shopping Mall Entrance (215). [1 mark] The Community Centre has the lowest pedestrian count (98). There is a clear hierarchy, with transport hubs having higher pedestrian traffic than the community centre. [1 mark]
Marking notes:
- Award 1 mark for identifying the highest and lowest locations with data.
- Award 1 mark for describing the overall pattern or trend (e.g., transport hubs have higher counts).
(b) Suggest one reason for the high pedestrian count at the MRT Station Exit compared to the Community Centre. [2 marks]
Answer: The MRT Station is a major transport node, serving a large number of commuters travelling to and from work, school, or other destinations, resulting in high footfall. [1 mark] In contrast, the Community Centre serves a more localised population and may only attract visitors for specific activities or events, leading to lower pedestrian traffic. [1 mark]
Marking notes:
- Award 1 mark for a valid reason related to the function of an MRT station (e.g., transport hub, high commuter volume).
- Award 1 mark for contrasting with the Community Centre's more limited/localised function.
12. (a) Suggest a suitable method to present the data in Table 2 graphically. Justify your choice. [3 marks]
Answer: A pie chart or divided bar graph would be suitable. [1 mark] The data shows the frequency of different land use types as parts of a whole (total of 20 points). [1 mark] A pie chart or divided bar graph effectively shows the proportion or percentage of each land use type, making it easy to compare their relative importance along the transect. [1 mark]
Marking notes:
- Award 1 mark for suggesting an appropriate graph type (pie chart, divided bar graph, percentage bar graph).
- Award 1 mark for justifying that the data represents parts of a whole/categories.
- Award 1 mark for explaining how the graph allows comparison of proportions/frequencies.
(b) With reference to the data, describe the distribution of land use along the transect. [2 marks]
Answer: Commercial land use is the most frequent (8 out of 20 points), followed closely by residential (7 out of 20 points). [1 mark] Mixed and industrial land uses are less common (3 and 2 points respectively). This suggests that commercial and residential uses dominate the transect from the city centre to the suburbs. [1 mark]
Marking notes:
- Award 1 mark for identifying the most and least frequent land use types with data.
- Award 1 mark for summarising the overall distribution or dominance.
13. Explain how a scatter graph could be used to show the relationship between two variables collected during fieldwork. Provide an example of two variables that could be investigated. [3 marks]
Answer: A scatter graph plots one variable on the x-axis and the other on the y-axis, with each point representing a paired observation. [1 mark] The pattern of points reveals the relationship: a positive correlation (points trend upwards), negative correlation (points trend downwards), or no correlation (random scatter). [1 mark] For example, it could be used to investigate the relationship between distance from a park (x-axis) and air quality index (y-axis). [1 mark]
Marking notes:
- Award 1 mark for explaining how axes represent the two variables.
- Award 1 mark for explaining how the pattern shows correlation/relationship.
- Award 1 mark for a relevant example of two variables that could be investigated.
Section D: Evaluation and Conclusion (14 marks)
14. (a) Evaluate the reliability of the data collection method used in this study. [4 marks]
Answer: The method has low reliability because measurements were taken only once at a single time on one day. [1 mark] Air quality can vary due to factors like weather conditions, traffic volume, and industrial activity at different times. [1 mark] A single measurement may not be representative of typical air quality. [1 mark] Additionally, using a handheld monitor may introduce human error if not calibrated or used consistently. [1 mark]
Marking notes:
- Award 1 mark for identifying the limited number of measurements/timing as a reliability issue.
- Award 1 mark for explaining why air quality varies (temporal variation).
- Award 1 mark for explaining lack of representativeness.
- Award 1 mark for mentioning potential instrument/human error.
(b) Suggest two improvements that could be made to the data collection to increase the reliability of the findings. [4 marks]
Answer (any two, 2 marks each):
- Take multiple measurements at each location at different times of the day and on different days (e.g., weekdays and weekends) and calculate an average. [1 mark] This would account for temporal variations in air quality and provide a more representative dataset. [1 mark]
- Use a calibrated, high-quality air quality monitor and ensure all measurements are taken at the same height and distance from potential obstructions. [1 mark] This standardises the measurement procedure and reduces instrument and human error. [1 mark]
- Increase the number of sampling locations to get a more detailed picture of how air quality changes with distance. [1 mark] This would improve the spatial resolution and reliability of the observed pattern. [1 mark]
Marking notes:
- Award up to 2 marks for each improvement: 1 mark for a specific, actionable suggestion, 1 mark for explaining how it increases reliability.
15. (a) Explain why using multiple data collection methods (triangulation) strengthens the validity of the findings. [3 marks]
Answer: Triangulation strengthens validity by cross-checking data from different sources or methods. [1 mark] If findings from land use surveys, environmental quality assessments, and resident questionnaires all point to the same conclusion about public amenities, the conclusion is more likely to be accurate and not an artefact of a single method's bias. [1 mark] It provides a more complete and nuanced understanding by capturing different dimensions of the research question. [1 mark]
Marking notes:
- Award 1 mark for defining triangulation as using multiple methods/sources.
- Award 1 mark for explaining cross-verification/reducing bias.
- Award 1 mark for explaining how it provides a more complete picture.
(b) The students concluded that "Neighbourhood X has better public amenities than Neighbourhood Y." Suggest one way the students could verify whether this conclusion is valid. [3 marks]
Answer: The students could compare their findings with official data or planning documents from government agencies (e.g., URA, HDB) that list the provision of public amenities in each neighbourhood. [1 mark] If the official data corroborates their field observations and resident perceptions, the conclusion is more valid. [1 mark] Alternatively, they could conduct a follow-up study with a larger, more representative sample of residents to see if the findings are consistent. [1 mark]
Marking notes:
- Award 1 mark for a specific, practical verification method.
- Award 1 mark for explaining how it would confirm or challenge the conclusion.
- Award 1 mark for linking to validity (e.g., corroboration, consistency).
16. During fieldwork, a student recorded observations in a notebook. Explain two reasons why it is important to record observations accurately and in detail during data collection. [4 marks]
Answer:
- Accurate and detailed records ensure that data is reliable and can be trusted for analysis. [1 mark] If observations are vague or incomplete, it may be difficult to draw valid conclusions or compare data across different locations or times. [1 mark]
- Detailed records provide context that may be important for interpreting results later. [1 mark] For example, noting weather conditions, unusual events, or specific characteristics of a location helps explain anomalies or patterns in the data. [1 mark]
Marking notes:
- Award up to 2 marks for each reason: 1 mark for identifying the reason, 1 mark for elaboration/example.
17. A group of students investigated the impact of tourism on a local community. They interviewed 10 residents and concluded that tourism has a positive impact. Evaluate the strength of this conclusion. [4 marks]
Answer: The conclusion is weak due to the very small sample size of only 10 residents. [1 mark] This sample is unlikely to be representative of the entire community's views, as opinions may vary widely depending on factors like occupation, location, or personal experience with tourism. [1 mark] The conclusion may be biased if the 10 residents were not randomly selected (e.g., they might all be business owners who benefit from tourism). [1 mark] A larger, more diverse sample and possibly quantitative data (e.g., surveys) would be needed to make a stronger, more generalisable conclusion. [1 mark]
Marking notes:
- Award 1 mark for identifying the small sample size as a weakness.
- Award 1 mark for explaining lack of representativeness.
- Award 1 mark for identifying potential bias in selection.
- Award 1 mark for suggesting how the conclusion could be strengthened (e.g., larger sample, random sampling).
18. Suggest one way that technology, such as GPS or mobile apps, could improve the accuracy of data collection during geographical fieldwork. [2 marks]
Answer: GPS can be used to accurately record the precise location of data collection points (e.g., where a survey was taken or a measurement was made). [1 mark] This eliminates human error in map reading or location description, ensuring that spatial data is reliable and can be mapped accurately for analysis. [1 mark]
Marking notes:
- Award 1 mark for a specific use of technology (e.g., GPS for location, mobile app for standardised data entry).
- Award 1 mark for explaining how it improves accuracy (e.g., reduces human error, ensures precision).
19. A student used a decibel meter to measure noise levels at three locations. The readings were 65 dB, 70 dB, and 68 dB. Calculate the mean noise level. Show your working. [2 marks]
Answer: Mean = (65 + 70 + 68) / 3 [1 mark] Mean = 203 / 3 = 67.67 dB (or 67.7 dB) [1 mark]
Marking notes:
- Award 1 mark for correct working/formula.
- Award 1 mark for correct answer (accept 67.67 or 67.7). Deduct 0.5 mark if units are missing or incorrect, but only if the mark scheme allows half marks; otherwise, award full marks if the value is correct.
20. Reflect on the importance of ethical considerations when conducting geographical fieldwork involving human participants. Provide one specific example of an ethical practice. [2 marks]
Answer: Ethical considerations are important to protect the rights, privacy, and well-being of participants and to ensure the integrity of the research. [1 mark] One example is obtaining informed consent from participants before conducting a questionnaire or interview, explaining the purpose of the research and how their data will be used, and giving them the right to withdraw at any time. [1 mark]
Marking notes:
- Award 1 mark for explaining the importance of ethics (e.g., protecting participants, research integrity).
- Award 1 mark for a specific, valid example of an ethical practice (e.g., informed consent, anonymity, confidentiality, avoiding harm).
