Question 6

Students used a Likert scale (Strongly Agree, Agree, Disagree, Strongly Disagree) to rate the quality of park facilities. Describe how the students could calculate the positive and negative scores for each facility. [3]




\

Question 10
In a survey of 50 residents, 30 responded "Agree" (+1) and 20 responded "Disagree" (-1) regarding a new development. Calculate the net satisfaction score. [2]




\

Question 11
Explain the process of "weighting" responses in a geographical survey. Why is this necessary? [3]





\

Question 12
A student collects data on pedestrian flow at 5-minute intervals for one hour. Suggest how this data could be processed to find the "peak flow" period. [2]




\

Question 13
Describe how a student could use a bipolar survey to assess the "sense of place" of a neighborhood. [3]





\

Question 14
If a student uses a sample size of only 5 people for a neighborhood survey, how does this affect the reliability of the data? [2]




\

Question 15
State one way a student could improve the accuracy of wind speed measurements taken with a handheld anemometer. [2]




\

Section C: Data Reliability and Evaluation (Questions 16–20)

Question 16
A study measured the amount of litter at three locations in a park. Data was collected once on a Monday morning. Evaluate whether this data collection is reliable. [4]




\

Question 17
A student uses a secondary source (a government website) to obtain data on Singapore's land reclamation. Discuss one advantage and one limitation of using this data compared to primary data. [4]





\

Question 18
Evaluate the reliability of a study that uses "stratified sampling" to collect opinions on sustainable tourism from 100 tourists of different nationalities. [4]





\

Question 19
A student concludes that "temperature always decreases as altitude increases" based on data collected from one mountain in one season. To what extent is this conclusion valid? [4]





\

Question 20
Compare the reliability of using a questionnaire versus using direct observation to study the impact of tourism on a local community. [4]

Answer Key - O-Level Geography Quiz (Map Graph Data Skills)

Section A: Data Representation and Interpretation

1. Answer: Use a grouped bar chart or a multi-line graph. (1m for graph type, 2m for explanation: e.g., "X-axis represents the four locations, Y-axis represents temperature, with different colored bars/lines for each location to allow direct comparison").
2. Answer: Line graph. (1m for type, 2m for justification: "Line graphs are best for showing changes over time/time-series data, allowing the trend of water consumption to be visualized").
3. Answer: (3m) Must include: Overall trend (e.g., increasing), specific data reference (e.g., from X to Y), and mention of any fluctuations or stability.
4. Answer: (2m) X-axis: Time/Month/Year; Y-axis: Rainfall amount/mm.
5. Answer: (2m) A pie chart shows parts of a whole (proportions/percentages), whereas a line graph shows changes over time. Land-use types are categories, not time-series.
6. Answer: (2m) Trend: The general direction in which something is developing or changing. Anomaly: A data point that deviates significantly from the established trend.
7. Answer: (3m) Scatter graph or line graph. X-axis: Height (m), Y-axis: Wind speed (m/s). Plot the three points and connect them to show the positive correlation.
8. Answer: (2m) It allows the researcher to see if there is a correlation (positive, negative, or none) between two continuous variables.

Section B: Calculation and Methodological Application

9. Answer: (3m) Assign numerical values to categories (e.g., Strongly Agree = +2, Agree = +1, Disagree = -1, Strongly Disagree = -2). Multiply frequency by weight. Sum the totals for positive and negative scores separately.
10. Answer: (2m) $(30 \times 1) + (20 \times -1) = 30 - 20 = +10$.
11. Answer: (3m) Weighting is assigning a numerical value to a qualitative response. Necessary because it allows qualitative opinions to be quantified and statistically analyzed.
12. Answer: (2m) Plot the 5-minute intervals on a line graph; the peak of the graph indicates the period with the highest volume of pedestrians.
13. Answer: (3m) Use a scale with opposite adjectives at each end (e.g., "Ugly" vs "Beautiful"). Respondents mark their perception on the line. This quantifies subjective feelings about a place.
14. Answer: (2m) Low reliability. The sample is too small to be representative of the whole neighborhood; results may be skewed by a few outliers.
15. Answer: (2m) Take multiple readings at the same spot and calculate an average to reduce the impact of wind gusts.

Section C: Data Reliability and Evaluation

16. Answer: (4m) Position: Unreliable. Evidence: Data collected only once (no temporal replication) and only on a Monday (weekdays differ from weekends). Explanation: Litter levels vary by day of the week and time of day. Qualification: While it provides a snapshot, it cannot represent the general pattern of the park.
17. Answer: (4m) Advantage: High accuracy/reliability as government data is usually professionally collected and comprehensive. Limitation: May be outdated or biased toward presenting a positive image of the state; lacks the "lived experience" of primary data.
18. Answer: (4m) Position: Highly reliable. Evidence: Stratified sampling ensures all nationalities are represented proportionally. Explanation: This reduces sampling bias and ensures the data isn't dominated by one specific group. Qualification: Reliability still depends on the honesty of the respondents.
19. Answer: (4m) Position: Partially valid/Limited. Evidence: Data from only one mountain and one season. Explanation: This is a case study, not a global rule. Other mountains or different seasons (e.g., temperature inversions) might show different patterns. Conclusion: The conclusion is an overgeneralization.
20. Answer: (4m) Questionnaire: Captures perceptions/feelings (subjective) but can be biased by respondent honesty. Observation: Captures actual behavior (objective) but cannot explain "why" people act that way. Conclusion: Reliability depends on the research goal (perceptions vs. behavior).
