Answers

Primary 5 Mathematics Quiz - Data Analysis (Answer Key)

Total Marks: 40
Topic: Data Analysis (syllabus-first, Stage 4/5 generated; no Stage 3 past-paper evidence available)

Section A (1 mark each)

Q1. Total = 4 + 6 + 3 + 6 + 5 = 24 books.
Teaching note: Add all bar heights from the chart. Mode is not asked; just sum.

Q2. Apple 8 + Pear 7 = 15 students.
Teaching note: Read the table and add the two rows.

Q3. Mode = 2 (appears three times: positions 1,5,6).
Teaching note: Mode is the value occurring most often. 2 appears 3 times, 0 twice, 1 twice, 3 once.

Q4. Sum of 4 numbers = 4 × 10 = 40. Fourth = 40 − (8+12+9) = 40 − 29 = 11.
Teaching note: Average × count = total. Subtract known to find missing.

Q5. 100% ÷ 4 = 25% each.
Teaching note: Full circle is 100%; equal parts split equally.

Q6. Cats 5 − Birds 2 = 3 more.
Teaching note: Tally: 5 cat marks, 2 bird marks.

Q7. Range = 33 − 29 = 4°C.
Teaching note: Range = highest − lowest.

Q8. 5 cm × 2 units/cm = 10 units.
Teaching note: Scale means each cm represents 2, so multiply.

Q9. Total of 5 = 5 × 80 = 400. Total of 4 = 4 × 78 = 312. Removed = 400 − 312 = 88.
Teaching note: Use total before and after.

Q10. 4 symbols × 5 = 20 children.
Teaching note: Pictograph key: 1 symbol = 5.

Section B (2 marks each)

Q11. Total = 12+18+10+20 = 60. Average = 60 ÷ 4 = 15 stickers.
Marking: 1 mark for total, 1 mark for division.
Teaching note: Average = sum ÷ count.

Q12. (a) Soda (25). (b) Total = 15+10+25+5 = 55.
Marking: 1m each.
Teaching note: Read tallest bar; sum all bars.

Q13. (a) Week3 13cm − Week1 4cm = 9cm. (b) Total growth = 17−4 = 13cm over 3 weeks → 13 ÷ 3 ≈ 4.33 cm/week.
Marking: 1m each. Accept 4⅓ or 4.3.
Teaching note: From graph values in placeholder. Average per week = (final−start) ÷ intervals.

Q14. (a) 9/30 = 3/10. (b) 12/30 = 40%.
Marking: 1m fraction simplified, 1m percent.
Teaching note: Fraction = part/whole; percent = fraction × 100.

Q15. Ordered: 15,20,25,30,30,40. (a) Median = (25+30)/2 = 27.5 min. (b) Mean = (20+25+30+15+30+40)=160 ÷ 6 ≈ 26.67 min.
Marking: 1m median, 1m mean.
Teaching note: Median for even count is middle pair average.

Q16. (a) 90°/360° = 1/4. (b) Science 120°/360° = 1/3 of 40 = 13⅓ → 13 or 14? Exact = 13.33, but students: 40 × 120/360 = 13.33, round to nearest whole = 13.
Marking: 1m fraction, 1m count.
Teaching note: Angle/360 = fraction of pie.

Section C (3 marks each)

Q17. (a) Thu (40). (b) 20+35+25+40+30 = 150. (c) 150 ÷ 5 = 30 apples/day.
Marking: 1m each.
Teaching note: From bar values in placeholder.

Q18. (a) Table: Bus 15, MRT 10, Walk 12, Car 13. (b) Range = 15−10 = 5. (c) New Walk = 12+10=22; 22/60 = 11/30.
Marking: 1m table, 1m range, 1m fraction.
Teaching note: Range from max−min of original counts.

Q19. (a) Mode = 5 (4 times). (b) Sum = 3+5+5+2+5+4+3+5+2+1 = 35; mean = 35 ÷ 10 = 3.5. (c) Mean lies between min (1) and max (5) because it is the balance point of all values.
Marking: 1m each.
Teaching note: Mean is affected by all values, so between extremes.

Q20. Sum = 26+28+27+29+30+31+25 = 196. (a) Mean = 196 ÷ 7 = 28°C. (b) Range = 31−25 = 6°C. (c) Above 28: Thu(29), Fri(30), Sat(31) → 3 days.
Marking: 1m each.
Teaching note: Compare each day to computed mean.
