Understanding Statistical Diagrams

My lower sixth have been learning about box and whisker plots and obtaining the necessary statistics from a cumulative frequency curve.

which shows a distribution, its cumulative frequency curve, the median and quartiles and the corresponding box and whisker plot.

Play around with the different aspects of the applet to understand the relationships.
