8. [2 marks] Describe how the students could calculate the positive and negative scores for each of the amenities in Table 1 below.

Table 1: Resident survey on amenities (Likert scale: Strongly Agree = +2, Agree = +1, Disagree = −1, Strongly Disagree = −2)

Amenity	Strongly Agree	Agree	Disagree	Strongly Disagree

Working: ___________________________________________________
Answer: _____________________________________________________

11. [3 marks] Study the bar chart described below.

Chart for Q11 (OLEVEL Geography)

City: ______________
Range: ______________ °C

12. [2 marks] A map extract shows a river with contour lines at 10 m intervals. Point L is at 20 m and Point M is at 50 m. Calculate the difference in height between L and M.

Difference: ______________ m

13. [3 marks] The students collected the following data on transport mode to school: Walk = 40%, Bus = 35%, Car = 25%. Show how this could be displayed and state one limitation of the display method.

14. [2 marks] A scatter graph shows a positive correlation between distance from city centre and rent price. State what this relationship means in geographical terms.

Section C: Data Reliability and Evaluation (Questions 15–20)

15. [2 marks] A student counted vehicles at a road junction for 10 minutes during lunch hour on one school day. State one reason why this data may not be reliable.

16. [4 marks] For the study described in Q15, evaluate whether the data collection is reliable. Use the method below.

Study: Vehicles counted at one junction, 10 min, lunch hour, one weekday.

17. [3 marks] The students used a questionnaire with closed questions to survey 30 residents about park cleanliness. Suggest two improvements to increase reliability.

18. [2 marks] State the meaning of "primary data" in geographical fieldwork.

19. [3 marks] A map shows earthquake epicentres along a plate boundary. Describe how you would use the map to identify the pattern of distribution.

20. [4 marks] Evaluate whether the use of a bar chart in Q2 (visitor numbers at four parks) is the most appropriate representation. Refer to alternatives.

Answers

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

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

Section A: Graph and Data Representation

Q1 [2 marks]

Answer: Use a grouped bar chart or two line graphs overlaid on the same axes (one line for Station A, one for Station B) with months on x-axis and rainfall (mm) on y-axis. (2 marks: 1 for graph type, 1 for correct axes/labeling)
Teaching note: Rainfall over months is continuous data across same period; overlay line graph or grouped bars allows direct comparison. Avoid two separate graphs.
Common mistake: Suggesting two pie charts.

Q2 [3 marks]

Answer: Use a bar chart with four bars (P, Q, R, S) on x-axis and visitor numbers on y-axis; OR a pie chart if proportion is intended. Best: bar chart for comparison. (3 marks: 1 graph type, 1 labeling of parks, 1 axis/units)
Teaching note: Categorical comparison of counts → bar chart. Include title, labelled axes, units.
Common mistake: Line graph (implies continuity between parks).

Q3 [2 marks]

Answer: Pie chart (or divided bar chart). (2 marks)
Teaching note: Proportion of parts of a whole → pie chart.

Q4 [2 marks]

Answer: Line graph shows trend/continuity over time; bar chart treats each month as separate. (2 marks: 1 point each)
Teaching note: Time-series needs line to show change.

Q5 [3 marks]

Answer: Use a line graph with time (9am, 12pm, 3pm) on x-axis, wind speed (km/h) on y-axis, and three lines (X, Y, Z) with legend. (3 marks: 1 type, 1 axes, 1 legend/multiple lines)
Teaching note: Same as template 1; overlay method for comparison.

Q6 [2 marks]

Answer: Paired bar chart (two bars per town: 2010, 2020) or line graph with towns as series. (2 marks)
Teaching note: Comparison over time for categories.

Q7 [2 marks]

Answer: Pie chart shows proportion of whole, not change over time; temperature across days is a sequence, not parts of one total. (2 marks)
Teaching note: Misuse of chart type.

Section B: Data Calculation and Interpretation

Q8 [2 marks]

Answer: Assign weights: SA=+2, A=+1, D=−1, SD=−2. Positive score = (SA×2)+(A×1). Negative score = (D×1)+(SD×2). Net = Positive + Negative. (2 marks: 1 for weighting, 1 for method)
Teaching note: From template 3; weighted Likert.

Q9 [2 marks]

Working: Positive = (10×2)+(15×1)=20+15=35. Negative = (5×1)+(2×2)=5+4=9. Net = 35−9 = 26.
Answer: 26 (2 marks: 1 working, 1 answer)

Q10 [2 marks]

Working: Positive = (8×2)+(12×1)=16+12=28. Negative = (6×1)+(4×2)=6+8=14. Net = 28−14 = 14.
Answer: 14 (2 marks)

Q11 [3 marks]

City: City B (Jan 12, Apr 18, Jul 30, Oct 16 → range 30−12=18). City A range = 30−28=2; City C = 26−20=6. Smallest = City A actually (2°C). Correction: City A range = 30−28 = 2°C.
Answer: City A, Range 2°C (3 marks: 1 city, 2 working/calc)
Teaching note: Range = max − min.

Q12 [2 marks]

Working: 50 m − 20 m = 30 m.
Answer: 30 m (2 marks)

Q13 [3 marks]

Answer: Display as pie chart (percentages). Limitation: hides actual student numbers; hard to compare small differences. (3 marks: 1 display, 2 limitation)
Teaching note: % data → pie; limitation on absolute counts.

Q14 [2 marks]

Answer: Rent increases as distance from centre increases (unusual; normally decreases) showing positive spatial association. (2 marks)
Teaching note: Positive correlation = both rise.

Section C: Data Reliability and Evaluation

Q15 [2 marks]

Answer: Only 10 min, one day → not representative of daily/weekly traffic. (2 marks)
Teaching note: Small sample/time.

Q16 [4 marks]

Mark breakdown: Position (1): Partially unreliable. Evidence (2): single location, short duration, weekday only. Qualification (1): if only snapshot needed, acceptable.
Teaching note: Template 2 structure.

Q17 [3 marks]

Answer: (1) Increase sample to 100+; (2) Use stratified sampling by age; (3) Repeat survey. Any two = 3 marks (1.5 each)
Teaching note: Reliability via sample size.

Q18 [2 marks]

Answer: Data collected first-hand by students (e.g., survey, measurement). (2 marks)

Q19 [3 marks]

Answer: Observe concentration along boundary; note clustering; measure spacing with ruler/scale. (3 marks: 1 observation, 1 pattern, 1 method)
Teaching note: Map pattern identification.

Q20 [4 marks]

Mark: Bar chart appropriate for comparison (2); alternatives: pie for proportion (1); evaluate fitness (1).
Teaching note: Template 1 variation.
