Answers

Primary 4 Mathematics Quiz - Data Analysis

Answer Key

Section A: Tables and Data Interpretation

Question 1 (1 mark)

Answer: 21
Working: Aisha's fiction books = 12, Ben's fiction books = 9. Total = 12 + 9 = 21
Marking note: Award 1 mark for the correct answer. No working required for 1-mark questions.

Question 2 (1 mark)

Answer: Ben
Working: Comics column: Aisha = 15, Ben = 18, Chloe = 10, David = 12, Elena = 14. The highest value is 18 (Ben).
Marking note: Award 1 mark for "Ben" only.

Question 3 (1 mark)

Answer: 7
Working: David's non-fiction = 13, Chloe's non-fiction = 6. Difference = 13 − 6 = 7
Marking note: Award 1 mark for the correct answer.

Question 4 (2 marks)

Answer: 31
Working: Poetry column: Aisha = 5, Ben = 2, Chloe = 10, David = 8, Elena = 6. Total = 5 + 2 + 10 + 8 + 6 = 31
Marking note: Award 2 marks for correct answer with or without working. Award 1 mark if the student adds correctly but makes one arithmetic error (e.g., writes 30 or 32).

Question 5 (2 marks)

Answer: Yes, the statement is correct. Elena read 10 fiction books and 6 poetry books. 10 − 6 = 4.
Working: From the table: Elena's fiction = 10, Elena's poetry = 6. Difference = 10 − 6 = 4. Since the difference is 4, the statement is verified.
Marking note: Award 2 marks for correct verification with working. Award 1 mark for correct numbers extracted from the table but incomplete or missing subtraction.

Question 6 (2 marks)

Answer: 10.4 (or 10 if rounding to nearest whole number, but accept 10.4)
Working: Fiction books: Aisha = 12, Ben = 9, Chloe = 14, David = 7, Elena = 10. Sum = 12 + 9 + 14 + 7 + 10 = 52. Average = 52 ÷ 5 = 10.4
Marking note: Award 2 marks for correct answer. Award 1 mark for correct sum (52) but incorrect or missing division. Accept 10.4 or 10½.

Question 7 (3 marks)

(a) (1 mark)

Answer: 40
Working: 16 + 9 + 11 + 4 = 40
Marking note: Award 1 mark for correct total.

(b) (2 marks)

Answer: 40
Working: Original total for 5 students = 40 × 5 = 200. Farhan's total = 40. New total = 200 + 40 = 240. Number of students = 6. New average = 240 ÷ 6 = 40
Marking note: Award 2 marks for correct answer with working. Award 1 mark for correct method with arithmetic error, or for finding the new total (240) but not completing the division.

Question 8 (2 marks)

Answer: 9 units
Working: Ben read 18 comics. Scale: 1 unit = 2 books. Height = 18 ÷ 2 = 9 units
Marking note: Award 2 marks for correct answer. Award 1 mark for correct division setup (18 ÷ 2) with wrong final answer.

Section B: Line Graphs

Question 9 (1 mark)

Answer: 28°C
Working: From the graph, at 6 a.m. the temperature is at the lowest point, which is 28°C.
Marking note: Award 1 mark for 28°C. Accept 28 without unit for 1 mark.

Question 10 (1 mark)

Answer: 34°C
Working: From the graph, at 12 p.m. the temperature reaches the highest point, which is 34°C.
Marking note: Award 1 mark for 34°C. Accept 34 without unit for 1 mark.

Question 11 (1 mark)

Answer: 8 a.m. to 9 a.m. (or 9 a.m. to 10 a.m.)
Working: The steepest part of the graph (greatest increase) appears between 8 a.m. and 9 a.m. where the temperature rises from approximately 30°C to 32°C (a 2°C increase in one hour). Accept any one-hour interval where the increase is greatest based on the graph.
Marking note: Award 1 mark for identifying the correct time interval. Accept "8 a.m. to 9 a.m." or "9 a.m. to 10 a.m." based on graph reading.

Question 12 (2 marks)

Answer: 6°C
Working: Highest temperature = 34°C (at 12 p.m.). Lowest temperature = 28°C (at 6 a.m.). Difference = 34 − 28 = 6°C
Marking note: Award 2 marks for correct answer. Award 1 mark for identifying both highest and lowest values correctly but making a subtraction error.

Question 13 (1 mark)

Answer: 9 a.m. (or 11 a.m.)
Working: From the graph, the temperature line passes through 31°C at approximately 9 a.m. (on the way up) and again at approximately 11 a.m. (on the way down). Accept either answer.
Marking note: Award 1 mark for either 9 a.m. or 11 a.m.

Question 14 (2 marks)

Answer: Yes, the statement is accurate. The temperature at 6 a.m. was 28°C and it increased to 34°C at 12 p.m. The graph shows a steady upward trend from 6 a.m. to 12 p.m. with no decreases during this period.
Working: From the graph: 6 a.m. = 28°C, 7 a.m. = 29°C, 8 a.m. = 30°C, 9 a.m. = 31°C, 10 a.m. = 32°C, 11 a.m. = 33°C, 12 p.m. = 34°C. The temperature increases by approximately 1°C each hour, showing a steady rise.
Marking note: Award 2 marks for "Yes" with correct explanation referencing data from the graph. Award 1 mark for "Yes" with incomplete or vague explanation. Award 0 marks for "No" regardless of explanation.

Section C: Pie Charts and Data Reasoning

Question 15 (2 marks)

Answer: 15 students
Working: Oranges = 25% of 60 students. 25% × 60 = 25/100 × 60 = 15 students
Marking note: Award 2 marks for correct answer. Award 1 mark for correct method (25% × 60 or equivalent) with arithmetic error.

Question 16 (2 marks)

Answer: 9 students
Working: Apples = 30% of 60 = 18 students. Grapes = 15% of 60 = 9 students. Difference = 18 − 9 = 9 students
Marking note: Award 2 marks for correct answer. Award 1 mark for finding both values (18 and 9) but not subtracting, or for correct method with one arithmetic error.

Question 17 (2 marks)

Answer: 1/5
Working: Bananas = 20%. 20% = 20/100 = 1/5 (simplified by dividing numerator and denominator by 20)
Marking note: Award 2 marks for 1/5. Award 1 mark for 20/100 (not simplified) or 2/10 (partially simplified). Do not accept 20% as a final answer since the question asks for a fraction.

Question 18 (3 marks)

Answer: 15%
Working: Original durian = 10% of 60 = 6 students. New durian count = 6 + 5 = 11. New total students = 60 + 5 = 65. Percentage = 11/65 × 100 = 16.92...% ≈ 17% (rounded to nearest whole number)
Marking note: Award 3 marks for correct answer (17%) with complete working. Award 2 marks for correct method with minor arithmetic error. Award 1 mark for finding the original number of durian students (6) or the new total (65) but not completing the calculation. Note: 16.92% rounds to 17%, not 15%.

Correction: The answer is 17%, not 15%. The working above is correct: 11 ÷ 65 × 100 = 16.92% ≈ 17%.

Question 19 (4 marks total)

(a) (1 mark)

Answer: March
Working: Comparing all values: 52,100 is the highest. This is in March.
Marking note: Award 1 mark for "March".

(b) (1 mark)

Answer: 52,000
Working: 52,100 rounded to the nearest thousand: look at the hundreds digit (1). Since 1 < 5, round down. 52,100 ≈ 52,000
Marking note: Award 1 mark for 52,000.

(c) (2 marks)

Answer: 13,350
Working: Highest = 52,100 (March). Lowest = 38,750 (February). Difference = 52,100 − 38,750 = 13,350
Marking note: Award 2 marks for correct answer. Award 1 mark for identifying both highest and lowest values correctly but making a subtraction error.

Question 20 (5 marks total)

(a) (3 marks)

Answer: Bar graph with correct heights:
- Reading: 10 students → 10 ÷ 2 = 5 units high
- Sports: 15 students → 15 ÷ 2 = 7.5 units high
- Music: 8 students → 8 ÷ 2 = 4 units high
- Art: 7 students → 7 ÷ 2 = 3.5 units high
Marking note: Award 3 marks for all four bars correctly drawn with correct heights. Award 2 marks for three correct bars. Award 1 mark for two correct bars. Deduct 1 mark if the student uses an incorrect scale (e.g., 1 unit = 1 student instead of 1 unit = 2 students).

(b) (2 marks)

Answer: 37.5%
Working: Total students = 10 + 15 + 8 + 7 = 40. Sports = 15. Percentage = 15/40 × 100 = 37.5%
Marking note: Award 2 marks for correct answer. Award 1 mark for correct fraction (15/40) but not converting to percentage, or for correct method with arithmetic error. Accept 37.5% or 38% if student rounds.
