Students learn how to compare sets of data using box and whisker diagrams to measure the interquartile range and median average.  As learning progresses cumulative frequency diagrams are used to create box plots.  This lesson comes with a worksheet to practise drawing box plots and another to practise drawing them from grouped data.

Differentiated Learning Objectives

• All students should be able to calculate the median from a Box and Whisker Diagram to comment on a distribution.
• Most students should be able to calculate the median and IQR from a Box and Whisker Diagram to comment on a distribution.
• Some students should be able to compare multiple distributions using the Median and IQG from a Box and Whisker diagram.
