Answers
O-Level Geography Quiz – Fieldwork: Answer Key and Marking Scheme
Total Marks: 40
Section A: Short Answer (10 marks)
1. State one reason why a pilot study is useful before conducting fieldwork. [1]
- Answer: To test the data collection instruments (e.g., questionnaire, observation checklist) and identify any problems before the actual data collection. / To check whether the sampling method is practical and whether the sites are accessible. / To estimate the time needed for data collection.
- Marking: Award 1 mark for any valid reason linked to testing, refining, or checking feasibility.
2. Identify one type of secondary data that could be used in a geographical investigation on tourism impacts. [1]
- Answer: Tourist arrival statistics from government agencies / Hotel occupancy rates / Maps of tourist facilities / Newspaper articles on tourism development / Previous research reports or academic studies.
- Marking: Award 1 mark for any valid example of secondary data relevant to tourism.
3. State the difference between random sampling and stratified sampling. [2]
- Answer: Random sampling gives every member of the population an equal chance of being selected, without any grouping. Stratified sampling divides the population into subgroups (strata) based on a characteristic, and then samples are taken from each subgroup.
- Marking: Award 1 mark for correctly describing random sampling, and 1 mark for correctly describing stratified sampling. Accept answers that clearly contrast the two methods.
4. A student measures wind speed at three locations using a handheld anemometer. Suggest one way the student could ensure the reliability of the measurements. [1]
- Answer: Take multiple readings at each location and calculate the average. / Ensure the anemometer is held at the same height and orientation at each location. / Use a calibrated instrument. / Take readings at the same time of day to control for diurnal variation.
- Marking: Award 1 mark for any valid method that improves consistency or repeatability.
5. Identify the type of data presentation method most suitable for showing the proportion of land use types in a neighbourhood. [1]
- Answer: Pie chart / Divided bar graph / Percentage bar graph.
- Marking: Award 1 mark for any graph type suitable for showing proportions or percentages of a whole.
Section B: Structured Questions (10 marks)
6. State one ethical consideration that students should observe when conducting questionnaire surveys with members of the public. [1]
- Answer: Obtain informed consent before asking questions. / Explain the purpose of the survey. / Allow respondents to remain anonymous. / Allow respondents to decline to answer or withdraw at any time. / Do not pressure respondents.
- Marking: Award 1 mark for any valid ethical consideration.
7. What is the difference between a research question and a hypothesis? [2]
- Answer: A research question is an open-ended question that guides the investigation (e.g., "How does water quality vary along the river?"). A hypothesis is a specific, testable statement that predicts the outcome of the investigation (e.g., "Water quality decreases downstream").
- Marking: Award 1 mark for correctly defining a research question, and 1 mark for correctly defining a hypothesis. Accept answers that clearly contrast the two.
8. Identify one limitation of using photographs as a data collection method in fieldwork. [1]
- Answer: Photographs capture only a single moment in time and may not represent typical conditions. / The photographer's choice of angle and framing may introduce bias. / Photographs provide qualitative data that is difficult to quantify or compare. / Weather or lighting conditions may affect image quality and comparability.
- Marking: Award 1 mark for any valid limitation.
9. Research question: "How does pedestrian traffic vary at different times of the day in a neighbourhood centre?"
(a) State a suitable hypothesis for this investigation. [1]
- Answer: "Pedestrian traffic is highest in the evening when residents return from work and school." / "Pedestrian traffic is lowest in the afternoon due to hotter temperatures." / "Pedestrian traffic peaks during morning and evening rush hours."
- Marking: Award 1 mark for a clear, testable statement that predicts a relationship between time of day and pedestrian traffic. The hypothesis must not be phrased as a question.
(b) Describe how the students could collect data to test this hypothesis. [3]
- Answer: Select specific locations within the neighbourhood centre (e.g., MRT exit, market entrance, playground). Conduct pedestrian counts at each location for a fixed duration (e.g., 10 minutes) at three different times of the day (morning, afternoon, evening). Use a tally counter or observation checklist to record the number of people passing a designated point. Repeat the counts on multiple days (e.g., one weekday and one weekend day) to improve reliability.
- Marking:
- 1 mark: Identifies data collection method (pedestrian count / observation).
- 1 mark: Describes sampling strategy (times of day, locations, duration).
- 1 mark: Mentions a measure to improve reliability (e.g., multiple days, fixed duration, clear counting criteria).
(c) Suggest one way the students could present the data they collected. Explain your choice. [2]
- Answer: A compound or grouped bar graph, with time of day on the x-axis and pedestrian count on the y-axis, using different coloured bars for each location. This allows easy visual comparison of pedestrian traffic across different times and locations. / A line graph with multiple lines (one per location) showing pedestrian count against time of day, which clearly shows trends and peaks.
- Marking:
- 1 mark: Identifies a suitable graph type (bar graph, line graph, compound bar graph).
- 1 mark: Explains why the graph type is suitable (e.g., allows comparison, shows trends, displays multiple variables).
10. Fieldwork investigation on water quality.
(a) Identify one strength of the sampling method used by the students. [1]
- Answer: Systematic sampling at equal intervals ensures coverage of the entire 2 km stretch of the river. / The method is objective and easy to replicate. / It avoids bias in site selection.
- Marking: Award 1 mark for any valid strength of systematic sampling.
(b) Identify and explain two limitations of the data collection method described. [4]
- Answer:
- Limitation 1: Only one reading was taken at each site. This means anomalies or errors in measurement cannot be detected, and the data may not be representative of typical conditions. Taking three readings and calculating an average would improve reliability.
- Limitation 2: Data was collected on a single afternoon. Water quality can vary due to weather conditions, time of day, or seasonal changes. Collecting data on multiple days or at different times would provide a more complete picture.
- (Accept other valid limitations, e.g., no recording of weather conditions, no measurement of other parameters like temperature or pollutants.)
- Marking:
- For each limitation: 1 mark for identifying a valid limitation, 1 mark for explaining why it is a limitation and/or how it could be improved.
- Maximum 4 marks (2 limitations × 2 marks each).
Section C: Data Response and Evaluation (10 marks)
11. Questionnaire survey on sense of place.
(a) Explain one weakness of this question. [2]
- Answer: The question is a closed question with only "Yes" or "No" options. This does not capture the strength or nuance of residents' feelings. A resident may feel a moderate sense of belonging but be forced to choose an extreme answer. / The question is leading or assumes a binary response, which limits the depth of data collected.
- Marking: 1 mark for identifying the weakness (closed question, binary response, lacks nuance). 1 mark for explaining how this limits the data collected.
(b) Rewrite the question to improve its usefulness for the investigation. [1]
- Answer: "On a scale of 1 to 5, how strongly do you feel a sense of belonging to this neighbourhood?" / "How would you describe your sense of belonging to this neighbourhood? (Very strong / Strong / Moderate / Weak / Very weak)" / "What aspects of this neighbourhood contribute to your sense of belonging?"
- Marking: Award 1 mark for any question that allows for a range of responses or more detailed qualitative data.
(c) Suggest one other method, besides a questionnaire, that could be used to investigate sense of place. Justify your choice. [2]
- Answer: Conduct semi-structured interviews with residents. This allows for in-depth exploration of personal feelings, experiences, and attachments to the neighbourhood, providing rich qualitative data. / Use mental mapping, where residents draw maps of their neighbourhood from memory. This reveals which places are most meaningful and how residents perceive their environment.
- Marking: 1 mark for identifying a suitable method. 1 mark for justifying why it is appropriate for investigating sense of place.
(d) Explain why using more than one data collection method can improve the validity of a fieldwork investigation. [2]
- Answer: Using more than one method (triangulation) allows cross-checking of data from different sources. If findings from different methods agree, confidence in the conclusions is increased. For example, questionnaire results showing strong sense of belonging can be supported by interview data expressing similar sentiments. This reduces the chance that findings are an artefact of a single method.
- Marking: 1 mark for explaining the concept of cross-checking or triangulation. 1 mark for explaining how this improves validity (e.g., reduces bias, increases confidence in findings).
12. Pedestrian count data.
(a) Using the data in Figure 1, describe the pattern of pedestrian traffic at Location A throughout the day. [2]
- Answer: Pedestrian traffic at Location A (MRT exit) is highest in the evening (187), followed by the morning (142), and lowest in the afternoon (98). There is a significant drop in the afternoon before rising sharply in the evening.
- Marking: 1 mark for identifying the trend (highest in evening, lowest in afternoon). 1 mark for supporting with data.
(b) Compare the pedestrian traffic patterns at Location B and Location C. Support your answer with data. [3]
- Answer: Both locations show an increase in pedestrian traffic from morning to afternoon. However, Location B (Hawker centre) has much higher overall counts than Location C (Playground). Location B peaks in the afternoon (156) and then decreases slightly in the evening (134), while Location C shows a steady increase throughout the day, from 12 in the morning to 67 in the evening. The difference in scale is significant; Location B's lowest count (89) is higher than Location C's highest count (67).
- Marking:
- 1 mark: Identifies a similarity (e.g., both increase from morning to afternoon).
- 1 mark: Identifies a difference in magnitude or trend.
- 1 mark: Supports comparison with specific data from Figure 1.
13. Refer to Figure 1. The students concluded that "the hawker centre is the busiest location overall." Using evidence from Figure 1, evaluate whether this conclusion is fully supported by the data. [3]
- Answer: The conclusion is not fully supported. While Location B (Hawker centre) has the highest afternoon count (156) and a high evening count (134), Location A (MRT exit) has a higher total count across the three time periods (142+98+187 = 427) compared to Location B (89+156+134 = 379). Location A is busiest in the morning and evening, and its overall total is higher. The conclusion is only valid if "overall" refers specifically to the afternoon period, but the data shows Location A has greater total pedestrian traffic.
- Marking:
- 1 mark: States that the conclusion is not fully supported.
- 1 mark: Provides evidence from Figure 1 (e.g., Location A's total is higher, or Location A is busiest in morning and evening).
- 1 mark: Explains why the conclusion is flawed or limited (e.g., ignores total counts, focuses only on one time period).
14. Refer to the pedestrian count investigation. Suggest one improvement to the data collection method that would allow the students to draw more reliable conclusions about pedestrian traffic patterns. Explain your answer. [2]
- Answer: Conduct counts on multiple days (e.g., both a weekday and a weekend day). Pedestrian traffic patterns can vary significantly between weekdays and weekends, so a single day's data may not be representative. Collecting data on different days would provide a more reliable picture of typical patterns. / Increase the duration of the count at each time slot (e.g., 30 minutes instead of 10 minutes) to capture a more representative sample of pedestrian flow.
- Marking: 1 mark for a valid improvement. 1 mark for explaining how it improves reliability.
15. The students wish to present the data in Figure 1 graphically. Suggest a suitable graph type and explain why it is appropriate. [2]
- Answer: A grouped bar graph is suitable. It allows easy visual comparison of pedestrian counts across the four locations for each time period (morning, afternoon, evening) by grouping bars by location or time. / A compound line graph with four lines (one for each location) would show trends over time clearly and allow comparison of patterns between locations.
- Marking: 1 mark for a suitable graph type. 1 mark for explaining why it is appropriate for this dataset.
Section D: Extended Application (10 marks)
16. Explain why it is important for a fieldwork investigation to have a clearly defined research question. [2]
- Answer: A clearly defined research question provides focus and direction for the entire investigation. It guides the choice of data collection methods, sampling strategies, and data analysis techniques. Without a clear question, the investigation may lack purpose, collect irrelevant data, and fail to reach meaningful conclusions.
- Marking: 1 mark for explaining focus/direction. 1 mark for linking to methods, analysis, or conclusions.
17. A student wants to investigate the impact of tourism on the environment at a coastal park. Suggest one primary data collection method and one secondary data source that could be used. Justify each choice. [4]
- Answer:
- Primary method: Environmental quality survey / bi-polar survey. The student could assess indicators such as litter, vegetation damage, and path erosion at different sites within the park. This provides first-hand, site-specific data on the visible environmental impacts of tourism.
- Secondary source: Park visitor statistics from the National Parks Board or relevant authority. This provides data on visitor numbers over time, which can be correlated with environmental impact data to assess the relationship between tourism pressure and environmental degradation.
- Marking:
- 1 mark for a valid primary method, 1 mark for justification.
- 1 mark for a valid secondary source, 1 mark for justification.
18. Describe one advantage and one disadvantage of using a land use survey to collect data in an urban fieldwork investigation. [2]
- Answer:
- Advantage: A land use survey provides a comprehensive, systematic record of how land is used across a study area. It allows for the creation of land use maps and quantitative analysis of land use patterns.
- Disadvantage: It can be time-consuming to conduct, especially over a large area. Also, categorising land use can be subjective (e.g., mixed-use buildings), which may affect consistency and accuracy.
- Marking: 1 mark for a valid advantage with description. 1 mark for a valid disadvantage with description.
19. A group of students collected data on noise levels at five different locations in a housing estate. They used a sound level meter app on a smartphone. Identify one potential limitation of this method and suggest how it could be overcome. [2]
- Answer:
- Limitation: Smartphone apps may not be accurately calibrated compared to professional sound level meters, leading to unreliable data.
- Solution: Calibrate the app using a known sound source or a professional meter before data collection. Alternatively, use the same smartphone and app for all measurements to ensure consistency, even if absolute accuracy is not perfect.
- Marking: 1 mark for identifying a valid limitation. 1 mark for a practical suggestion to overcome it.
20. Evaluate the importance of sampling in geographical fieldwork. Use examples to support your answer. [4]
- Answer: Sampling is crucial in geographical fieldwork because it is usually impractical or impossible to collect data from an entire population or study area. Sampling allows researchers to gather representative data efficiently. For example, when investigating water quality along a 10 km river, it is not feasible to test every metre; systematic sampling at 1 km intervals provides a manageable overview. However, the importance of sampling depends on the choice of method. Poor sampling (e.g., biased site selection or too small a sample size) can lead to inaccurate conclusions. For instance, convenience sampling for a questionnaire might only capture the views of easily accessible people, not the whole community. Therefore, while sampling is essential for practical fieldwork, its value is only realised when an appropriate, justified sampling strategy is used to ensure data is representative and reliable.
- Marking:
- 1 mark: Explains why sampling is necessary (practicality, representation).
- 1 mark: Provides a relevant example of sampling in fieldwork.
- 1 mark: Discusses a limitation or risk of poor sampling.
- 1 mark: Provides a balanced evaluation linking sampling strategy to data quality.
