Primary 5 Mathematics Quiz - Data Analysis (Answer Key)

Total Marks: 50

---

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

1. Answer: (2) 10

Working:
Total books = 8 + 12 + 5 + 15 + 10 = 50
Number of students = 5
Average = Total ÷ Number = 50 ÷ 5 = 10

Concept: Average = Sum of all values ÷ Number of values

2. Answer: (3) 2 pm

Working:
From the line graph, the highest point is at 2 pm with a temperature of 34°C.
8 am: 26°C, 10 am: 28°C, 12 pm: 32°C, 2 pm: 34°C, 4 pm: 30°C, 6 pm: 26°C

Concept: Reading line graphs – the highest point on the graph corresponds to the maximum value.

3. Answer: (2) 35

Working:
Ivan's stamps = 80
Farah's stamps = 45
Difference = 80 – 45 = 35

Concept: Reading bar graphs – compare heights of bars to find values, then subtract.

4. Answer: (2) 24

Working:
Banana sector angle = 120°
Total angle of pie chart = 360°
Total pupils = 80
Number who chose Banana = (120° ÷ 360°) × 80 = ⅓ × 80 = 26.67...
Wait, let me recalculate: 120/360 = 1/3. 1/3 × 80 = 26.67? That's not a whole number.
Let me check: 120° out of 360° is exactly 1/3. 80 ÷ 3 = 26⅔. This is not possible for number of pupils.
Correction: The question data has an issue. 80 pupils cannot be divided into 120° sector evenly.
However, based on the options, 24 is the closest to a reasonable calculation if total was 72 (120/360 × 72 = 24).
But given the options and typical P5 questions, the intended answer is likely (2) 24 assuming a total of 72 pupils, or there's a typo in the question.
Marking note: Accept (2) 24 as the intended answer based on standard pie chart calculation method.

Concept: Pie chart – fraction of circle × total = number in category.
Angle of sector ÷ 360° × Total = Quantity

5. Answer: (2) 2

Working:
Goals: 2, 3, 1, 4, 2, 3
Frequency: 1 appears once, 2 appears twice, 3 appears twice, 4 appears once
Mode = value that appears most often. Both 2 and 3 appear twice.
This is bimodal. But in P5, if there are two modes, either could be accepted or the question expects the smallest.
Given options, both 2 and 3 are options. Typically the first mode encountered or smallest is chosen.
Marking note: Accept (2) 2 or (3) 3. But standard convention: mode = 2 and 3 (bimodal). If forced to choose one, 2 is the first mode.

Concept: Mode = most frequently occurring value. Data can have more than one mode.

6. Answer: (2) 2nd hour (1–2 hours)

Working:
Distance each hour:
1st hour (0–1): 10 – 0 = 10 km
2nd hour (1–2): 22 – 10 = 12 km
3rd hour (2–3): 32 – 22 = 10 km
4th hour (3–4): 40 – 32 = 8 km
5th hour (4–5): 46 – 40 = 6 km
Greatest distance = 12 km in 2nd hour.

Concept: Reading line graphs – find difference in y-values between consecutive x-values to get rate/distance per interval.

7. Answer: (2) 330

Working:
Week 1: 80, Week 2: 100, Week 3: 60, Week 4: 90
Total = 80 + 100 + 60 + 90 = 330

Concept: Reading bar graphs – sum the values represented by each bar.

8. Answer: (2) 19 cm

Working:
Heights in order: 15, 17, 18, 20, 22, 25
Number of plants = 6 (even)
Median = average of 3rd and 4th values = (18 + 20) ÷ 2 = 38 ÷ 2 = 19 cm

Concept: Median = middle value when data is ordered. For even number of data points, median = average of two middle values.

9. Answer: (2) $15

Working:
Transport sector angle = 90°
Total money = $60 Amount on Transport = (90° ÷ 360°) ×$60 = ¼ × $60 =$15

Concept: Pie chart – fraction of circle × total = amount for category.

10. Answer: (3) 150

Working:
April visitors = 350
June visitors = 500
Increase = 500 – 350 = 150

Concept: Reading line graphs – find values at two points, subtract to find increase/decrease.

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

11. Answer: 10 pencils (2 marks)

Working:
Total pencils = 12 + 8 + 15 + 10 + 5 = 50
Number of pupils = 5
Average = 50 ÷ 5 = 10

Marking:

• 1 mark for correct total (50)
• 1 mark for correct average (10) with unit

12. Answer: 27 cups (2 marks)

Working:
Ping = 6, Qi = 9, Ravi = 4, Siti = 8
Total = 6 + 9 + 4 + 8 = 27

Marking:

• 1 mark for reading all 4 values correctly from graph
• 1 mark for correct total (27) with unit

13. Answer: 230 g (2 marks)

Working:
Week 2 mass = 320 g
Week 5 mass = 550 g
Increase = 550 – 320 = 230 g

Marking:

• 1 mark for reading both values correctly from graph
• 1 mark for correct subtraction and unit

14. Answer: 23 pupils (2 marks) — Note: 140/360 × 60 = 23.33, not whole number

Working:
Blue sector angle = 140°
Total pupils = 60
Number = (140° ÷ 360°) × 60 = (7/18) × 60 = 420/18 = 23⅓

Marking note: This question has a data issue – 60 pupils cannot give a whole number for 140°.
Accept 23 or 23⅓ with working shown. In actual P5 exams, numbers are chosen to give whole numbers.
Better total would be 54 pupils (140/360 × 54 = 21) or 72 pupils (140/360 × 72 = 28).

Marking:

• 1 mark for correct method (angle/360 × total)
• 1 mark for correct calculation based on given numbers

15. Answer: 30 sit-ups (2 marks)

Working:
Sit-ups: 25, 30, 28, 35, 22, 30, 27
Frequency: 22(1), 25(1), 27(1), 28(1), 30(2), 35(1)
Mode = 30 (appears twice, most frequent)

Marking:

• 1 mark for identifying frequency or ordering data
• 1 mark for correct mode with unit

16. Answer: 25 toy cars (2 marks)

Working:
Mon=15, Tue=25, Wed=20, Thu=30, Fri=35
Total = 15 + 25 + 20 + 30 + 35 = 125
Number of days = 5
Average = 125 ÷ 5 = 25

Marking:

• 1 mark for correct total (125)
• 1 mark for correct average (25) with unit

17. Answer: April (2 marks)

Working:
From graph: Jan=100, Feb=80, Mar=150, Apr=200, May=180, Jun=120
Highest rainfall = 200 mm in April

Marking:

• 1 mark for reading all values or identifying highest point
• 1 mark for correct month

18. Answer: 6.5 books (2 marks)

Working:
Books in order: 4, 5, 5, 6, 7, 8, 9, 10
Number of pupils = 8 (even)
Median = average of 4th and 5th values = (6 + 7) ÷ 2 = 13 ÷ 2 = 6.5

Marking:

• 1 mark for correct ordering of data
• 1 mark for correct median calculation with unit

19. Answer: 13 pupils (2 marks) — Note: 120/360 × 40 = 13.33, not whole number

Working:
Bus sector angle = 120°
Total pupils = 40
Number = (120° ÷ 360°) × 40 = ⅓ × 40 = 13⅓

Marking note: Data issue – 40 not divisible by 3.
Accept 13 or 13⅓ with working.
Better total would be 39 pupils (120/360 × 39 = 13) or 42 pupils (120/360 × 42 = 14).

Marking:

• 1 mark for correct method (angle/360 × total)
• 1 mark for correct calculation based on given numbers

20. Answer: 25 marks (2 marks)

Working:
Marks: Tom=65, Uma=80, Vic=70, Wei=90, Xin=75
Highest = 90 (Wei)
Lowest = 65 (Tom)
Range = Highest – Lowest = 90 – 65 = 25

Marking:

• 1 mark for identifying highest and lowest correctly
• 1 mark for correct range calculation with unit

Marking Summary

Section	Questions	Marks per Question	Total Marks
A (MCQ)	1–10	1	10
B (Short Answer)	11–20	2	20
Total	20		30

Note: The quiz is marked out of 30 marks (10 + 20), not 50 as stated on the cover. The cover should say Total Marks: 30 or Section B should have 20 questions × 2 marks = 40 marks for a 50-mark total. This answer key follows the actual questions provided (30 marks total).

Common Mistakes to Avoid

1. Average vs Total: Always divide total by number of items for average.
2. Median for even data: Remember to average the two middle numbers.
3. Mode: Can have more than one mode (bimodal). If asked for "the mode" and there are two, state both.
4. Pie charts: Use fraction = angle/360. Check that total × fraction gives whole number.
5. Line graphs: Read values at exact points. For increase over period, subtract start from end.
6. Bar graphs: Read scale carefully. Check intervals (e.g., each interval = 2, 5, 10, 20).
7. Range: Highest minus lowest. Not the same as "total" or "average".
8. Units: Always include units in final answer (pupils, books, cm, g, $, etc.).

---

Teaching Notes for Students

• Average (Mean): "Share equally" – add all, divide by how many.
• Median: "Middle" – order first, then find middle. Even number → average of two middle.
• Mode: "Most popular" – which appears most often. Can have none, one, or many modes.
• Range: "Spread" – biggest minus smallest.
• Pie Charts: Whole circle = 360° = 100% = Total quantity. Sector angle ÷ 360° = fraction of total.
• Line Graphs: Show change over time. Steep upward = fast increase. Flat = no change. Downward = decrease.
• Bar Graphs: Compare quantities. Height/length of bar = value. Read scale carefully!
• Tables: Organise data. Check row/column headings. Use for calculating average, median, mode, range.
