Graph for Q5 (OLEVEL Geography)

Generated graph for Q5.

Describe one difference in rainfall pattern between Town A and Town B. [1]

7. Table 1 shows wind speed (km/h) recorded at 6 stations.

Station	Wind speed (km/h)
1	12
2	18
3	15
4	21
5	14
6	16

Calculate the mean wind speed. [2]

8. Using the table in Q7, find the range of wind speed. [1]

9. A survey used a Likert scale: Strongly Agree = +2, Agree = +1, Disagree = −1, Strongly Disagree = −2. For amenity X: 10 Strongly Agree, 5 Agree, 3 Disagree, 2 Strongly Disagree. Calculate the net score. [2]

10. Study the pie chart of land use in a town.

Chart for Q10 (OLEVEL Geography)

Generated chart for Q10.

Calculate the area used for green space. [1]

11. Using the pie chart in Q10, calculate the area used for commercial purposes. [1]

12. Study the scatter plot of temperature vs ice cream sales.

Graph for Q12 (OLEVEL Geography)

Generated graph for Q12.

Describe the relationship shown. [1]

13. A map shows 4 earthquake epicentres along a line. Explain what this suggests about plate boundary location. [2]

Section C: Evaluation and Higher-Order Skills (Questions 14–20) [14 marks]

14. For a study, students measured river depth at 3 sites using a ruler once per site. Evaluate whether the data collection is reliable. [4]

15. Explain how GIS could be used to investigate urban heat islands in Singapore. Discuss one advantage and one limitation. [3]

16. A class tested: "Beach sediment size decreases with distance from cliff." They used systematic sampling every 5 m for 50 m, measuring 10 pebbles per site. Evaluate the methodology. [3]

17. Study the topographic map extract.

Map for Q17 (OLEVEL Geography)

Generated map for Q17.

Describe the slope steepness on the west side and explain how you know. [2]

18. Students collected rainfall data using one rain gauge for 1 week. Suggest two improvements to increase reliability. [2]

19. A bar chart compares recycling rates in 3 housing estates. Explain how you would check if the graph is misleading. [2]

20. To what extent can graphs alone prove cause-and-effect in geography? Evaluate using an example. [3]

TuitionGoWhere Practice Paper Answer Key — Geography O-Level (Version 3)

Topic: Map, Graph & Data Skills
Total Marks: 40

Section A Answers

Q1 [2 marks]
Answer: Use a bar chart with stations on x-axis and temperature on y-axis, OR a line graph if comparing across a variable.
Teaching note: For categorical comparison (stations), bar chart is suitable. Mark breakdown: 1 mark for graph type, 1 mark for labelling axes/legend.
Common mistake: Suggesting 4 separate graphs instead of one combined.

Q2 [1 mark]
Answer: June (180 thousand).
Teaching note: Read highest bar from provided chart values.

Q3 [2 marks]
Answer: 120 + 135 + 150 = 405 thousand.
Working: Jan 120 + Feb 135 + Mar 150 = 405.
Mark: 1 for correct addition, 1 for unit (thousands).

Q4 [2 marks]
Answer: Line graph; because distance is continuous and shows change/trend.
Mark: 1 type, 1 reason.

Q5 [1 mark]
Answer: Town A has highest rainfall in Jan (80mm) and lowest in Apr (30mm); Town B peaks later (Apr 60mm). Any valid difference.
Teaching: Read both lines.

Q6 [2 marks]
Answer: Line graph with time on x-axis and cars on y-axis (shows change over time).
Mark: 1 graph, 1 justification.

Section B Answers

Q7 [2 marks]
Mean = (12+18+15+21+14+16) ÷ 6 = 96 ÷ 6 = 16 km/h.
Working shown; 1 mark formula, 1 mark answer+unit.

Q8 [1 mark]
Range = 21 − 12 = 9 km/h.

Q9 [2 marks]
Net = (10×2)+(5×1)+(3×−1)+(2×−2) = 20+5−3−4 = 18.
Step-by-step: SA 20, A 5, D −3, SD −4; total 18.
Mark: 1 calculation, 1 answer.

Q10 [1 mark]
Green space = 15% of 200 = 30 km².

Q11 [1 mark]
Commercial = 25% of 200 = 50 km².

Q12 [1 mark]
Positive correlation: as temperature rises, sales increase.

Q13 [2 marks]
Answer: Epicentres along a line suggest a linear plate boundary (e.g., transform or convergent).
Mark: 1 line suggests boundary, 1 explanation.

Section C Answers

Q14 [4 marks]
Position: Partially reliable (1). Evidence: only one measurement per site, no repeat → low reliability (1). Small sample 3 sites (1). Counter: quick method but bias possible (1).
Descriptors: clear position, specific method reference, balanced.

Q15 [3 marks]
GIS overlays temperature, land cover, buildings (1). Advantage: visualises hotspots (1). Limitation: needs accurate input data (1).

Q16 [3 marks]
Strengths: systematic sampling reduces bias (1). Limitations: 50m short, 10 pebbles small sample (1). Overall partial (1).

Q17 [2 marks]
West side steep (1) because contours close together (1).

Q18 [2 marks]
Two improvements: more gauges, longer period. (1 each)

Q19 [2 marks]
Check y-axis starts at 0, scale consistent, labels clear. (1+1)

Q20 [3 marks]
Graphs show correlation not causation (1). Example: ice cream sales and drowning (1). Need other evidence (1).
