Primary 6 PSLE Mathematics Quiz - Data Analysis (Answer Key)

Total Marks: 50


Section A: Multiple-Choice Questions (10 × 1 mark = 10 marks)

1. Answer: (3) 60
Working:
Total students = 200
Angle for Bananas = 108°
Number of students = 108°360°×200=310×200=60\frac{108°}{360°} \times 200 = \frac{3}{10} \times 200 = 60
Concept: In a pie chart, the angle of a sector represents the proportion of the whole. sector angle360°×total=quantity\frac{\text{sector angle}}{360°} \times \text{total} = \text{quantity}.

2. Answer: (1) 50
Working:
Books in March = 300
Books in May = 350
Increase = 350 − 300 = 50
Concept: Read values from line graph at specific points, then find difference.

3. Answer: (2) 165
Working:
Total stamps = 120 + 150 + 180 + 210 = 660
Average = 6604=165\frac{660}{4} = 165
Concept: Average = Sum of all valuesNumber of values\frac{\text{Sum of all values}}{\text{Number of values}}.

4. Answer: (4) Friday
Working:
Cars on Monday = 10
Twice = 20
Day with 20 cars = Wednesday? Wait, check: Wed=20, but 20 is twice 10. Actually Wednesday has 20 cars. But option (2) is Wednesday, (4) is Friday. Let me re-read: "twice the number sold on Monday". Monday=10, twice=20. Wednesday=20. So answer should be Wednesday. But wait, the options: (1) Tuesday (15), (2) Wednesday (20), (3) Thursday (25), (4) Friday (30). So answer is (2) Wednesday.
Correction: Answer: (2) Wednesday
Concept: Read bar heights, compute target value, match to correct day.

5. Answer: (3) 13\frac{1}{3}
Working:
Angle for Food = 120°
Fraction = 120°360°=13\frac{120°}{360°} = \frac{1}{3}
Concept: Fraction of whole = sector angle360°\frac{\text{sector angle}}{360°}.

6. Answer: (3) 40
Working:
Sum of 5 numbers = 5 × 28 = 140
Sum of 6 numbers = 6 × 30 = 180
Sixth number = 180 − 140 = 40
Concept: When average changes with added number, use: new sum − old sum = added number.

7. Answer: (3) 5°C
Working:
Highest temperature = 33°C (Day 6)
Lowest temperature = 28°C (Day 1)
Difference = 33 − 28 = 5°C
Concept: Range = maximum value − minimum value.

8. Answer: (3) 32%
Working:
Total pupils = 40 + 35 + 38 + 42 = 155
Total wearing spectacles = 12 + 10 + 14 + 16 = 52
Percentage = 52155×100%33.55%\frac{52}{155} \times 100\% \approx 33.55\%? Wait, let me recalculate.
40+35+38+42 = 155. 12+10+14+16 = 52. 52/155 = 0.33548... × 100% = 33.55%. That's not matching any option. Let me check the numbers again.
Maybe I made an error. 40+35=75, +38=113, +42=155. Yes. 12+10=22, +14=36, +16=52. Yes. 52/155 = 33.55%. Options are 28%, 30%, 32%, 34%. Closest is 34%? But 33.55% rounds to 34%? Or maybe the numbers are different. Let me adjust the question numbers to make it exact.
Actually, for the answer key, I'll use the numbers as given and compute correctly. 52/155 × 100% = 33.55% ≈ 34% if rounding to nearest whole number. But typically PSLE expects exact. Let me change the table values to make it exact 32%.
If total pupils = 160, total spectacles = 51.2? No. Let's make total pupils = 150, spectacles = 48 → 32%.
But the question is already written. For the answer key, I'll state the correct calculation based on given numbers and note the closest option.
Better: I'll adjust the answer to (4) 34% as the intended answer with rounding, or note the discrepancy.
Actually, let me recalculate: 52/155 = 0.3355. The options are 28, 30, 32, 34. 33.55 is closest to 34. But in PSLE, they usually make it exact. I'll assume the question had a typo and the intended answer is 32% with different numbers. For this answer key, I'll show the working with given numbers and state the exact percentage.
Working with given numbers:
Total pupils = 155, Total with spectacles = 52
Percentage = 52155×100%=3365155%33.55%\frac{52}{155} \times 100\% = 33\frac{65}{155}\% \approx 33.55\%
Since this doesn't match exactly, but option (4) 34% is closest, the intended answer is likely (4) with rounding.
Marking note: Accept (4) 34% as correct if rounding to nearest whole number is expected.

9. Answer: (3) 40 kg
Working:
Total mass = 4 + 6 + 8 + 10 + 12 = 40 kg
Concept: Sum of bar values.

10. Answer: (1) 10
Working:
Angle for Dogs = 108° → 60 families
1° = 60108=59\frac{60}{108} = \frac{5}{9} families
Angle for Hamsters = 36°
Families with Hamsters = 36 × 59\frac{5}{9} = 20? Wait: 36 × 5/9 = 20. But option (1) is 10, (3) is 20. So answer is (3) 20.
Let me recalculate: 108° → 60 families. So 1° → 60/108 = 5/9 families. 36° → 36 × 5/9 = 20 families. Yes, answer is 20. Option (3).
Correction: Answer: (3) 20
Concept: Use proportion: angle1quantity1=angle2quantity2\frac{\text{angle}_1}{\text{quantity}_1} = \frac{\text{angle}_2}{\text{quantity}_2}.


Section B: Short-Answer Questions (10 × 2 marks = 20 marks)

11. (a) Answer: 5
Working:

Greatest growth = 7 cm (Week 5 to Week 6)
Concept: Find difference between consecutive points on line graph; largest difference = most growth.

(b) Answer: 5 cm
Working:
Total growth = 30 − 5 = 25 cm over 5 intervals (or 6 weeks from start)
Average growth per week = 255=5\frac{25}{5} = 5 cm/week
Alternative: Average growth = Final heightInitial heightNumber of weeks1=30561=5\frac{\text{Final height} - \text{Initial height}}{\text{Number of weeks} - 1} = \frac{30-5}{6-1} = 5 cm/week
Concept: Average rate of change = Total changeNumber of intervals\frac{\text{Total change}}{\text{Number of intervals}}.

13. (a) Answer: 60
Working:
Angle for Blue = 120°
Number of pupils = 120°360°×180=13×180=60\frac{120°}{360°} \times 180 = \frac{1}{3} \times 180 = 60
Concept: Same as pie chart proportion.

(b) Answer: 16.7% (or 16⅔%)
Working:
Angle for Green = 60°
Percentage = 60°360°×100%=16×100%=1623%16.7%\frac{60°}{360°} \times 100\% = \frac{1}{6} \times 100\% = 16\frac{2}{3}\% \approx 16.7\%
Concept: Percentage = fraction × 100%.

14. (a) Answer: 1300
Working:
Total visitors = 150 + 200 + 300 + 250 + 400 = 1300
Concept: Sum of bar values.

(b) Answer: 6500Working:Totalmoney=1300×6500 **Working:** Total money = 1300 × 5 = $6500
Concept: Total = quantity × unit price.

15. Answer: 34 kg
Working:
Total mass of 3 boys = 3 × 42 = 126 kg
Total mass of 4 boys = 4 × 40 = 160 kg
Mass of 4th boy = 160 − 126 = 34 kg
Concept: Use average formula backwards: new total − old total = added value.

16. (a) Answer: 17
Working:
Total goals = (0×2) + (1×3) + (2×2) + (3×2) + (4×1)
= 0 + 3 + 4 + 6 + 4 = 17
Concept: For frequency table, total = Σ (value × frequency).

(b) Answer: 1.7
Working:
Mean = Total goalsTotal matches=1710=1.7\frac{\text{Total goals}}{\text{Total matches}} = \frac{17}{10} = 1.7
Concept: Mean = (x×f)f\frac{\sum (x \times f)}{\sum f}.

17. Answer: 1066.67(or1066.67 (or 1066⅔)
Working:
Angle for Transport = 80°
Fraction = 80°360°=29\frac{80°}{360°} = \frac{2}{9}
Amount = 29×4800=96009=106623=1066.67\frac{2}{9} \times 4800 = \frac{9600}{9} = 1066\frac{2}{3} = 1066.67
Concept: Find fraction from angle, multiply by total.

18. (a) Answer: 15 L/h
Working:
Volume decreases from 100 L to 10 L over 6 hours.
Total decrease = 90 L
Rate = 90 L6 h=15 L/h\frac{90 \text{ L}}{6 \text{ h}} = 15 \text{ L/h}
Alternative: From graph, each hour decreases by 15 L (100→85→70→55→40→25→10).
Concept: Rate = Change in volumeChange in time\frac{\text{Change in volume}}{\text{Change in time}} (constant rate = straight line).

(b) Answer: 6⅔ hours (or 6 hours 40 min)
Working:
Initial volume = 100 L
Rate = 15 L/h
Time to empty = 10015=203=623\frac{100}{15} = \frac{20}{3} = 6\frac{2}{3} hours = 6 hours 40 minutes

Working:
Distances: 35, 38, 40, 42, 45
Range = Maximum − Minimum = 45 − 35 = 10 km
Concept: Range = largest value − smallest value.

(b) Answer: 46 km
Working:
Total distance of 5 cyclists = 42+38+45+40+35 = 200 km
New average for 6 cyclists = 41 km
Total distance for 6 cyclists = 6 × 41 = 246 km
Cyclist F distance = 246 − 200 = 46 km
Concept: Same as Q15: new total − old total = added value.


Marking Notes for Teachers

  • Section A: 1 mark each. No partial credit. Accept only the option number.

  • Section B: 1-2 marks per part. Award method marks for correct working even if final answer has calculation error.

  • Common Errors:

    • Q4: Confusing "twice Monday" with other days. Must compute 2×10=20 first.
    • Q8: Percentage calculation with non-exact division. Accept rounding to nearest whole number if intended.
    • Q12(b): Using 6 weeks instead of 5 intervals for average growth.
    • Q18(b): Forgetting that tank starts at 100L, not 0L.
    • Q19: Arithmetic errors in multiplication/addition. Encourage systematic table.
    • Q20(b): Using 5 cyclists instead of 6 for new total.
  • Key Concepts Tested:

    • Reading and interpreting pie charts, bar graphs, line graphs, tables
    • Calculating average, median, mode, range
    • Using proportions in pie charts (angle ↔ quantity)
    • Rate of change from line graphs
    • Reverse average problems (finding added value)
    • Multi-step problems combining data reading with arithmetic
