In the Department of Basic Education’s teaching plan, Grade 7 data handling is taught in Term 4. It comes up in the Grade 7 maths Term 4 test, and again in the final Term 4 exam, which covers all four terms.
Sample Grade 7 data handling questions
Five questions of the kind the test asks. In the test itself every answer is marked straight away, with the working shown.
1. Determine the median:
Show the answer
Answer: 57
Put them in order first: 25 ; 32 ; 57 ; 60 ; 86. The middle value is 57.
2. A graph shows temperature against time through the day. Should the points be joined?
- No, because each reading stands alone
- Yes, because temperature changes continuously
- No, because time jumps from hour to hour
- Yes, because the graph should look tidy
Show the answer
Answer: Yes, because temperature changes continuously
Continuous data changes without gaps. Between two readings there was a temperature, so you join the points.
3. Which measure shows how far the data is spread?
- mode
- mean
- range
- median
Show the answer
Answer: range
The range is the largest value minus the smallest.
4. Determine the range:
Show the answer
Answer: 59
Range = largest − smallest = 75 − 16 = 59.
5. Which point lies on the line y = 3x + 3?
- (1 ; 12)
- (2 ; 10)
- (2 ; 9)
- (3 ; 9)
Show the answer
Answer: (2 ; 9)
Replace x with 2: 3 × 2 + 3 = 9. So the point (2 ; 9) lies on the line.
Common mistakes in Grade 7 data handling
Reading the wrong axis, ignoring the key on a pictograph where one picture stands for two, and mixing up the mode and the median.
