Lesson details
Key learning points
- Data presented as a list can be represented as a bar chart
- Data presented in a table can be represented as a bar chart
- The type of data determines how the bars should be drawn
Keywords
Frequency - The frequency is the number of times an event occurs; or the number of individuals (people, animals etc.) with some specific property.
Bar chart - A bar chart (bar graph) is a graph consisting of bars visually representing the frequency of objects or groups.
Data - Data are a collection of information.
Common misconception
Pupils may label the vertical axis with the frequency values rather than a scale.
Remind the pupils that the scale should go up in the same jumps. i.e. 0, 5, 10, 15 etc and have them check theirs.
