## Lesson details

### Key learning points

- When presented with a large volume of data, valid interpretation can be hard.
- It is important that any conclusions are supported by the data.
- In the real world, multiple representations are often used so critiquing them is a vital skill.

### Common misconception

Claims can be made based on the data displayed in a chart.

A claim is only valid for the particular selection of data shown. This can mean that any conclusions are very limited.

### Keywords
