What are stem and leaf diagrams?
A stem and leaf diagram is named due to the way it is drawn. A stem refers to the 'tens' and leaves refer to the 'ones' or 'units' and is a great way to organise a long list of numbers. Stem and leaf diagrams are part of the statistics family but they may not be mentioned explicitly, they may be hidden in 'displaying data', 'data handling' or 'types of data'.
