Topic: Map, Graph & Data Skills
Total Marks: 60

Section A

1. [3 marks]
Answer: Use a line graph or grouped bar chart with months on x-axis and rainfall on y-axis; plot 4 lines/bars for stations A–D with legend.
Teaching: Continuous monthly data compared across 4 sites → line graph shows trends; bar chart compares discrete values. Must label axes (months, rainfall mm), include units, legend.
Marking: 1 mark graph type, 1 mark single graph with all stations, 1 mark labelling/legend.

2. [2 marks]
Answer: Line graph; reason: shows trend over time (months).
Teaching: Time-series data → line graph best. 1 mark type, 1 mark reason.

3. [3 marks]
Answer: Single line graph, x-axis height (2,10,20 m), y-axis temp °C, 3 lines for each height with legend.
Teaching: Comparing same variable at different heights → overlay lines. Marks: 1 graph type, 1 all on one, 1 labels.

4. [2 marks]
Answer: 2020s, 11 cyclones.
Teaching: Read tallest bar from placeholder. 1 mark decade, 1 mark value.

5. [2 marks]
Answer: Pie chart shows proportion at one time, not change over time; wind speed over day is time-series.
Teaching: 1 mark pie unsuitable for trend, 1 mark reason time-series.

6. [1 mark]
Answer: (Based on placeholder: if T is north of R) T (bus stop).
Teaching: Read map relative position.

7. [2 marks]
Working: Agree 10×1=10; Disagree 5×−1=−5; Net=10−5=+5.
Answer: +5.
Teaching: Apply weights, sum. 1 mark calc, 1 mark final.

Section B

8. [2 marks]
Answer: Line X increases steadily from 26°C (0800) to 32°C (1300).
Teaching: Read values, state rise. 1 mark trend, 1 mark values.

9. [4 marks]
Answer: Partially reliable. Evidence: 10-min surveys short, 5 locations small sample. But standardised time reduces bias. Counter: more sites needed.
Teaching: Position (1), evidence method (2), qualification (1).

10. [2 marks]
Working: (300−120)/120×100 = 150%.
Answer: 150%.
Teaching: % increase formula. 1 mark calc, 1 mark answer.

11. [3 marks]
Answer: Earthquakes clustered along plate boundary line; linear pattern; most within close distance.
Teaching: Describe spatial. 1 mark cluster, 1 mark along boundary, 1 mark pattern.

12. [3 marks]
Answer: Grouped bar chart: x-axis sites, 3 bars per site for times, legend for times.
Teaching: Compare categories. 1 type, 1 all shown, 1 labels.

13. [2 marks]
Working: (12+15+18+22+25)/5 = 92/5 = 18.4.
Answer: 18.4 (000s).
Teaching: Mean = sum/n.

14. [4 marks]
Answer: Photo shows real detail (buildings use) but limited extent; map shows distribution clearly but not detail. Both useful, photo less reliable for area.
Teaching: Position (1), photo strength (1), map strength (1), trade-off (1).

Section C

15. [2 marks]
Working: Pos = 8×2 + 10×1 = 26; Neg = 4×1 + 2×2 = 8.
Answer: Positive 26, Negative 8.

16. [3 marks]
Answer: Apr (200mm), Nov (220mm); temp steady ~27–28°C.
Teaching: Read dual axis. 1 mark months, 2 marks temp desc.

17. [4 marks]
Answer: Low reliability: 20 questionnaires small, one mall not representative. But focused. Need larger sample.
Teaching: As template 2.

18. [3 marks]
Answer: Scatter graph, x distance, y rent, plot points, look for correlation.
Teaching: 1 type, 1 axes, 1 use.

19. [2 marks]
Working: 12/15×100 = 80%.
Answer: 80%.

20. [4 marks]
Answer: Use small multiples or grouped bar with river on x, 3 bars (width, depth, velocity) but diff units need normalisation; or 3 separate panels. Best: 3 line graphs with normalised index.
Teaching: 1 mark identify issue units, 2 marks method, 1 mark labelling.
