Answers

Primary 3 Mathematics Quiz - Data Analysis (Answer Key)

Total Marks: 40
Topic: Data Analysis (bar graphs and picture graphs)

Section A Answers (1 mark each)

6
Teaching note: A bar graph uses the height of the bar to show the number. Ali’s bar reaches 6, so he read 6 books. Common mistake: misreading the scale.
6 pupils
Method: 1 star = 2 pupils, Mei has 3 stars → 3 × 2 = 6. Picture graphs use symbols to stand for a number.
Apple
Mango = 5, Apple = 8. 8 > 5, so Apple is more popular.
3
Buses = 7, Cars = 4. Difference = 7 − 4 = 3.
10 stickers
1 circle = 5 stickers, Sam has 2 → 2 × 5 = 10.
Dog
Cat = 9, Dog = 6. 6 < 9, so Dog has fewer.
Green
Red = 3, Blue = 5, Green = 2. Smallest is 2 (Green).
40 trees
1 tree symbol = 10, 4 symbols → 4 × 10 = 40.
Class A
Class A = 12, Class B = 15. 12 < 15, so Class A scored less.
4
Bar drawn to 4 means the value is 4.
