i. The type of measurement for the data is interval and the scale of measurement is discrete.
ii. A histogram chart would be used to represent the above data.
iii. [Please note that I am unable to create an actual chart in this text-based format, but here is a description of how you could create a histogram for this data:
- On the x-axis, label each bar with the ranges of marks (0-9, 10-19, 20-29, 30-39, 40-49).
- On the y-axis, label the number of students.
- Create bars for each range with the height corresponding to the number of students in that range: 10 students for 0-9, 8 students for 10-19, 12 students for 20-29, 15 students for 30-39.
- Your histogram should have 5 bars representing each range of marks.]
Marks 0 - 9 10 -19 20 - 29 30 - 39 40 - 49
No of students 10 8 12 15
The table below shows student marks.
i. Name the type and the scale of measurement for the above set of data. (2 marks)
ii. What chart would be used to represent the above? (1 mark)
iii. Create a chart you have selected above (7 marks)
