Answers
Primary 4 Mathematics Quiz - Data Analysis (Answer Key)
Total Marks: 40
Section A: Multiple-Choice Questions (10 × 1 mark = 10 marks)
1. Answer: C [1]
Working:
Total = 8 + 12 + 5 + 10 = 35
Concept: Reading data from a table and finding the sum.
2. Answer: B [1]
Working:
From the line graph, at the 3rd hour (x = 3), the temperature is 25°C.
Concept: Reading values from a line graph by locating the x-coordinate (time) and finding the corresponding y-coordinate (temperature).
3. Answer: C [1]
Working:
Angle for Bananas = 108°
Total angle in a circle = 360°
Fraction = 108° / 360° = 3/10
Number of students = (3/10) × 40 = 12
Concept: Interpreting pie charts – angle proportion represents fraction of total.
4. Answer: B [1]
Working:
Total cars = 6 + 8 + 5 + 9 + 7 = 35
Number of days = 5
Average = 35 ÷ 5 = 7
Concept: Average = Total ÷ Number of items.
5. Answer: B [1]
Working:
Growth Week 1→2: 9 − 5 = 4 cm
Growth Week 2→3: 14 − 9 = 5 cm
Growth Week 3→4: 18 − 14 = 4 cm
Greatest growth = 5 cm (Week 2 to Week 3)
Concept: Comparing differences between consecutive data points on a line graph.
6. Answer: C [1]
Working:
Highest = 58 (Cat), Lowest = 27 (Dan)
Difference = 58 − 27 = 31
Concept: Finding range (difference between maximum and minimum values).
7. Answer: C [1]
Working:
Angle for Food = 135°
Fraction = 135° / 360° = 3/8
Amount = (3/8) × 30
Concept: Using pie chart angles to find actual values from a given total.
8. Answer: A [1]
Working:
From the graph, Day 1 has 40 visitors (lowest value).
Concept: Identifying the minimum value on a line graph.
9. Answer: B [1]
Working:
Scores in order: 68, 72, 77, 83, 85, 91
6 scores (even number), so median = average of 3rd and 4th values
Median = (77 + 83) ÷ 2 = 160 ÷ 2 = 79.5
Concept: Median for even number of data points = average of two middle values.
10. Answer: B [1]
Working:
Class A = 45, Class D = 50 → Total = 95
Check others: A+B=105, B+C=95, C+D=85
Concept: Reading bar graph values and testing combinations.
Section B: Short-Answer Questions (5 × 2 marks = 10 marks)
11. (a) Answer: 120 [1]
Working:
24 + 18 + 30 + 22 + 26 = 120
Marking note: 1 mark for correct total.
11. (b) Answer: 24 [1]
Working:
Average = Total ÷ Number of days = 120 ÷ 5 = 24
Marking note: 1 mark for correct average. Follow-through from (a) allowed.
12. (a) Answer: 80 [1]
Working:
At 0 hours (start), the graph shows 80 litres.
Marking note: 1 mark for reading the y-intercept correctly.
12. (b) Answer: 15 [1]
Working:
Water decreases from 80 L to 5 L over 5 hours.
Total decrease = 80 − 5 = 75 L
Rate = 75 L ÷ 5 h = 15 L/h
(Alternatively: constant decrease of 15 L each hour as seen from points)
Marking note: 1 mark for correct rate with unit.
13. (a) Answer: 1/3 [1]
Working:
Angle for Swimming = 120°
Fraction = 120° / 360° = 1/3
Marking note: 1 mark for simplest form fraction.
13. (b) Answer: 8 [1]
Working:
Soccer angle = 100°, Cycling angle = 50°
Difference in angle = 50°
Each degree = 60 ÷ 360 = 1/6 pupil
Difference in pupils = 50 × (1/6) = 8.33... → Wait, must be whole number.
Better: Soccer = (100/360) × 60 = 16.67? No, angles must give whole numbers.
Let's recalculate: 120+90+100+50 = 360° ✓
Soccer: (100/360)×60 = 50/3 = 16.67 — not whole!
Correction: The angles given (120, 90, 100, 50) sum to 360 but don't divide 60 evenly. This is a flaw in the question design. For a proper P4 question, angles should be multiples of 6° (since 360/60 = 6° per pupil).
Adjusted marking: Accept 8 or 9 with valid working.
Proper working for intended answer 8:
If we assume the question expects: Soccer = 100° → 100/360 × 60 = 16.67 ≈ 17? No.
Let's use: Difference in angle = 50°. 50° ÷ 6° per pupil = 8.33.
Better approach for answer key: State the issue and give intended answer.
Intended answer: 8 (using 50° × 60/360 = 8.33, but P4 expects whole numbers so angles should be multiples of 6).
Marking note: 1 mark for correct method (angle difference × total/360). Accept 8 or 8.33 with working.
14. (a) Answer: 2.5 [1]
Working:
Masses: 2.5, 3.2, 1.8, 4.0, 2.5
2.5 appears twice (most frequent).
Mode = 2.5 kg
Marking note: 1 mark for correct mode with unit.
14. (b) Answer: 14.0 [1]
Working:
Total = 2.5 + 3.2 + 1.8 + 4.0 + 2.5 = 14.0 kg
Marking note: 1 mark for correct total with unit.
15. (a) Answer: 40 [1]
Working:
At 1 hour, distance = 40 km. At 0 hours, distance = 0 km.
Distance in 1st hour = 40 − 0 = 40 km
Marking note: 1 mark for correct reading and subtraction.
15. (b) Answer: 30 [1]
Working:
Total distance = 120 km (at 4 hours)
Total time = 4 hours
Average speed = 120 ÷ 4 = 30 km/h
Marking note: 1 mark for correct average speed with unit.
Section C: Structured / Long-Answer Questions (5 × 4 marks = 20 marks)
16. (a) Answer: 39 [1]
Working:
4 + 7 + 5 + 9 + 6 + 8 = 39
Marking: 1 mark for correct total.
16. (b) Answer: 6.5 [1]
Working:
Average = 39 ÷ 6 = 6.5
Marking: 1 mark for correct average. Accept 6.5 or 6 1/2.
16. (c) Answer: 7 [2]
Working:
New total = 39 + 10 = 49
New number of pupils = 7
New average = 49 ÷ 7 = 7
Marking: 1 mark for new total (49), 1 mark for new average (7).
Common mistake: Forgetting to add the new pupil to the count (dividing by 6 instead of 7).
17. (a) Answer: 34 °C at 2 p.m. [1]
Working:
Highest point on graph is 34°C at 2 p.m.
Marking: 1 mark for both correct temperature and time.
17. (b) Answer: 5 [1]
Working:
8 a.m. = 28°C, 12 p.m. = 33°C
Increase = 33 − 28 = 5°C
Marking: 1 mark for correct increase with unit.
17. (c) Answer: From 2 p.m. to 4 p.m. [1]
Working:
Drops: 6am→8am: +2, 8am→10am: +2, 10am→12pm: +3, 12pm→2pm: +1, 2pm→4pm: −2, 4pm→6pm: −3
Largest drop = 3°C (from 4 p.m. to 6 p.m.)
Wait: 2pm (34) to 4pm (32) = drop of 2°C. 4pm (32) to 6pm (29) = drop of 3°C.
So largest drop is from 4 p.m. to 6 p.m.
Correction: Answer should be "From 4 p.m. to 6 p.m."
Marking: 1 mark for correct interval.
17. (d) Answer: 31.5 °C (accept 31–32 °C) [1]
Explanation: 11 a.m. is halfway between 10 a.m. (30°C) and 12 p.m. (33°C). The temperature increases linearly, so estimate = (30 + 33) ÷ 2 = 31.5°C.
Marking: 1 mark for reasonable estimate (31–32°C) with valid explanation (interpolation between two known points).
18. (a) Answer: 1/5 [1]
Working:
Walk angle = 72°
Fraction = 72° / 360° = 1/5
Marking: 1 mark for simplest form fraction.
18. (b) Answer: 24 [1]
Working:
Bus angle = 108°
Number = (108/360) × 80 = (3/10) × 80 = 24
Marking: 1 mark for correct number.
18. (c) Answer: 0 [1]
Working:
Car angle = 90°, MRT angle = 90°
Both = (90/360) × 80 = 20 students each
Difference = 20 − 20 = 0
Marking: 1 mark for correct answer (0 students).
18. (d) Answer: 130.5 ° [1]
Working:
Originally: Walk = 72° → 16 students (since 72/360 × 80 = 16)
Bus = 108° → 24 students
After change: Walk = 11 students, Bus = 29 students
New Bus angle = (29/80) × 360° = 130.5°
Marking: 1 mark for correct angle.
Alternative method: Each student = 360°/80 = 4.5°. 5 more students → 5 × 4.5° = 22.5° increase. 108° + 22.5° = 130.5°.
19. (a) [2]
Marking:
- 1 mark: Axes labelled correctly (Year on x-axis, Number of Participants on y-axis), appropriate scale used (e.g., 1 cm = 1 year on x-axis, 1 cm = 50 participants on y-axis), points plotted accurately at (2020,120), (2021,150), (2022,180), (2023,210), (2024,240).
- 1 mark: Points connected with straight line segments, graph neat.
Expected graph: Straight line with constant positive gradient (increase of 30 per year).
19. (b) Answer: 270 participants [1]
Reasoning: The number of participants increases by 30 each year (constant trend). 2024: 240, so 2025: 240 + 30 = 270.
Marking: 1 mark for correct prediction with valid reasoning (constant increase of 30 per year).
19. (c) Answer: 30 [1]
Working:
Target for 2026 = 300
Current (2024) = 240
Total increase needed over 2 years (2024→2025, 2025→2026) = 300 − 240 = 60
Yearly increase = 60 ÷ 2 = 30 participants per year
Marking: 1 mark for correct yearly increase.
20. (a) [3]
Angles to be drawn:
- Chocolate: (30/100) × 360° = 108°
- Vanilla: (25/100) × 360° = 90°
- Strawberry: (20/100) × 360° = 72°
- Mint: (15/100) × 360° = 54°
- Others: (10/100) × 360° = 36°
Check: 108 + 90 + 72 + 54 + 36 = 360° ✓
Marking:
- 1 mark: All 5 angles calculated correctly (shown in working or on chart).
- 1 mark: Sectors drawn accurately with protractor (within ±2° tolerance).
- 1 mark: Sectors labelled with flavour names (or legend provided).
20. (b) Answer: 55 [1]
Working:
Chocolate + Vanilla = 30 + 25 = 55 children
Percentage = (55/100) × 100% = 55%
Marking: 1 mark for correct percentage with % sign.
