TuitionGoWhere Practice Paper — Answer Key (Version 5)
Subject: Geography (O-Level)
Topic: Map, Graph & Data Skills
Total Marks: 40
Section A Answers (10 marks)
Q1. [1] Mean = (26 + 31 + 29) ÷ 3 = 86 ÷ 3 = 28.7°C (accept 28.7 or 29°C rounded).
Teaching note: Mean is sum ÷ count. Common mistake: omitting one reading.
Q2. [1] x-axis: months (or time); y-axis: rainfall amount (mm).
Teaching note: Bar graphs use categorical x and continuous y.
Q3. [1] 4 cm × 25 000 = 100 000 cm = 1 km.
Method: Scale 1:25 000 means 1 cm = 250 m; 4 × 250 = 1000 m.
Q4. [1] Line graph shows trend over time; pie chart shows proportion only.
Accept any valid advantage.
Q5. [1] 10 × (+1) = +10.
Teaching note: Likert weight × frequency.
Q6. [1] positive.
Teaching note: Both variables rise together = positive correlation.
Q7. [1] frequency.
Modal class = class with highest frequency (10–20).
Q8. [1] overlay (or spatial).
GIS overlay combines layers.
Q9. [1] similar / consistent.
Reliability = repeatability.
Q10. [1] bars: rainfall; line: temperature.
Standard climate graph.
Section B Answers (16 marks)
Q11. [3] Use a bar chart with parks A–D on x-axis and visitor numbers on y-axis. [1] One combined graph (not separate). [1] Label axis "Average visitors" and give legend/title. [1]
Marking: 3 marks for correct graph type, combined, labelled.
Q12. [2] Net score = (Agree × +1) + (Disagree × −1). [1] Bench: 12−8=+4; Shelter: 5−15=−10. [1]
Teaching note: Show substitution per amenity.*
Q13. [4] Mean X = (26+27+28+29+29+30)÷6 = 169÷6 = 28.2°C. [2] Difference: X consistently higher than Y by about 2°C each month. [2]
From image_placeholder: lines show X above Y. Mark: 2 for calc, 2 for valid contrast.
Q14. [3] Enter coordinates and sediment size into GIS. [1] Create point layer along transect. [1] Use colour ramp to show size change with distance. [1]
Teaching note: GIS visualises spatial gradient.
Q15. [3] Range R = 310 − 290 = 20 mm. [2] Indicates low variation month to month. [1]
Method: max − min.
Q16. [5] Position: Partially reliable. [1] Strengths: systematic 5 m interval reduces bias; 3 repeats improve consistency. [2] Weakness: only 25 m may miss further change; road type not stated. [1] Conclusion: usable for near-road but not full area. [1]
Marking descriptors: clear eval with evidence.
Section C Answers (14 marks)
Q17. [3] Count bus stops within 300 m of each school. [1] Score = number of stops / total distance to river. [1] School A closer to river and may have more stops → higher score. [1]
From map: distances given; use scale.
Q18. [4] Net = (5×2)+(10×1)+(8×−1)+(2×−2) = 10+10−8−4 = +8. [2] Positive net shows more agreement than disagreement → perceived positively. [2]
Teaching note: weight × freq, sum.
Q19. [3] Remote sensing via satellite thermal bands shows temperature zones. [2] Limitation: cloud cover may block images. [1]
Accept other valid limitation.
Q20. [4] Not reliable for annual: one day not representative. [2] Calm day underestimates typical wind. [1] Need multiple days/seasons. [1]
Marking: clear eval of representativeness.
Total: 40 marks verified.
