Data & Graphs
Histograms, range and line graphs
What your child practises
Telling discrete data (counted) from continuous data (measured), reading histograms and line graphs, finding the range, and spotting misleading graphs.
Ontario Curriculum expectation: D1.1–D1.6 · discrete and continuous data, histograms, broken-line graphs, range, and misleading graphs
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.
