In this lesson, students examine two box plots showing marks obtained by two classes.

First, they have to interpret the box plots, working out what the plots are showing and how this enables them to draw conclusions about the two classes.

Then, students are asked to create possible data that could have led to these plots and explore which changes to their data points affect features of the box plots and which don’t.

In this way, students become increasingly fluent with connecting the data points to the representation.

Why teach this?

The ability to make sense of visual representations of data is vital to statistical literacy
