Lesson details
Key learning points
- Data presented as a list can be represented as a pie chart.
- Data presented in a table can be represented as a pie chart.
- A larger data set requires considering the proportion of the total.
Keywords
Sector - A sector is the region formed between two radii and their connecting arc.
Common misconception
The frequencies on the frequency table are the angles you plot onto the pie chart.
Challenge the misconception by using an example with frequencies that clearly add to more or less than 360 e.g. {90, 90, 180, 90, 60)
