Sample questions
A taste of this unit. In the app, questions change every time and get easier or harder to match your child.
Question 1
How many students were counted in all?
Minutes spent reading (histogram) Minutes Students 0–9 12 10–19 11 20–29 7 30–39 12 - 38
- 42
- 40
Show answer
42
Hint: Add the counts for every interval.
Question 2
Between which two times did the temperature rise the most?
Temperature (°C) through the day Time °C 8 a.m. 5 10 a.m. 5 12 p.m. 7 2 p.m. 10 - 8 a.m. to 10 a.m.
- 12 p.m. to 2 p.m.
- 10 a.m. to 12 p.m.
Show answer
12 p.m. to 2 p.m.
Hint: On a broken-line graph, the steepest climb shows the biggest rise.
Question 3
How many students read for 30–39 minutes?
Minutes spent reading (histogram) Minutes Students 0–9 12 10–19 4 20–29 4 30–39 2 - 6
- 2
- 7
Show answer
2
Hint: Find the row for that interval.
Question 4
Is this data discrete or continuous? the goals scored in a game
- continuous
- discrete
Show answer
discrete
Hint: Discrete data is counted and has gaps. Continuous data is measured and can be any value in a range.
Question 5
Which data set has the greater range?
Set A Set B 14 18 5 12 10 16 18 26 29 22 - Set A
- Set B
Show answer
Set A
Hint: Find the range of each set. The greater range is more spread out.
Question 6
Is this data discrete or continuous? the number of pets in a home
- discrete
- continuous
Show answer
discrete
Hint: Discrete data is counted and has gaps. Continuous data is measured and can be any value in a range.
